One of the images presented of Diana, Princess of Wales, is that she was always alone. It’s easy to see how she was cast in that role in her final years, even if the details weren’t completely accurate. She was certainly removed from her former husband since he showed he had other social, familial, and romantic priorities. As a divorced royal, she had fewer social privileges and obligations since she was the mother of future royalty. Since she was a public figure of interest, she also stayed in the public eye, whether she liked it or not.

She still had her sons, she had her charities, and she had several friends who she confided in. Of course, she still had to be careful about what she did and who she interacted with in public. But not everyone knew she was quite good at correspondence with friends, some who were also in the public eye and even some longtime colleagues who preferred their privacy assisted her in taking her mind off the day-to-day spotlight and all of the challenges that came with going against the grain of the monarchy.

Her famous letters are able to give a better insight into her life and her views of the world. Like her public persona, Diana in her letters came across as bright, even funny, but also felt stressed about the pressures put upon her, even after she was officially divorced from the royal family.

Over the years, more of her famous letters have turned up. Some of her friends may have passed away, and their family/heirs decided to put their letters up for auction. Other friends have decided to put their letters into the public domain so people can learn more about what she was really like.

The letters also offer interesting insight into different points of her life, from significant moments to more routine moments where she relished some of the calm around her.

Some interesting famous letters were shared between her and longtime friend Roger Bramble. These included things like Christmas cards or routine items like how her day was or her reaction to an unflattering biography of her life that was recently published.

Letters to and from another friend, Cyril Dickman, not only share what’s on her mind, but what’s happening to those around her, specifically what her sons were getting up to at school.

Cyril Dickman was a longtime steward at Buckingham Palace, and also a longtime confidante of Princess Diana, even after she fell out of royal favor.   

For instance, in the late 1980s and early 1990s, she would write to him about how her two boys were doing at boarding school. William, for instance, was always a good student, but Harry did have more of a habit of getting into trouble, even at a young age.

At the same time, she said William always did what he could to look out for his little brother, especially when they were at school together in their younger days. This included hugs when needed.

As a rule, the most survivable engines are usually not the most advanced in design, without superchargers and other technical frills. Although there are some exceptions. We have based our rating on our experience and the recommendations of servicemen. One more thing. Do not be surprised if some of our listed engines cannot be met on modern cars; in fact, it takes time to compile complete statistics, but there are plenty of them available on the secondary market.

VW 1.6 MPI EA 211

Let’s change the ten from the VW 1.6 MPI EA 211 motor. This unit was designed as a simple and unpretentious engine for inexpensive models of concern. Our compatriots are familiar with it from the Polo model, which has been produced in Kaluga since 2010. We cannot say that the engine has turned out perfect in terms of reliability, although it has generally proven quite durable and reliable. True, at first had to put up with oil consumption – the consumption of liquid lubricant sometimes reached up to 500 grams per 1000 km of run. After the change of the piston group design, the consumption decreased noticeably. At the same time, instead of the chain, there was a belt in the timing belt drive. It is believed that since 2015, the engine has eliminated most of its issues. However, oil consumption in some copies still remains, as well as oil and coolant leakage through the gaskets. The motor is available in two power variants: 90 and 110 horsepower. Its service life is 250,000 to 300,000 km.

Opel 1.8 Z18XER

The Opel 1.8-liter Z18XER series four was installed not only in the Vectra, Astra, and Insignia, but also in related GM models. By design, the engine is quite simple – distributed injection, no hydro-compensator valves. Only the variable valve timing system can be called from technical novelties. Maybe that is why it is able to run 300,000 km, and often even more before overhaul. Telling the truth, before it it is necessary to change the timing belt, valve cover gaskets, heat exchanger, and crankshaft oil seals. However, it is not very expensive. In addition, the engine is good and maintainable, and the parts are inexpensive. More info by link https://yurovskiy.info/

Hyundai/Kia 1.6 G4FC

This engine has been installed in Solaris and Rio since 2010. In the second generation of these models, the unit received a second Phase Shifter on the exhaust shafts. The engine is based on an aluminum block and cylinder head, with the timing drive being a metal chain that has a lifespan of at least 150,000 km. The valve slack is mechanically adjusted every 40,000 km. The weak points include the catalyst, which can fail even after 50-70,000 km. The main thing is to recognize the malfunction in a timely manner and take appropriate measures. Otherwise, the ceramic particles from the destroyed catalytic converter enter the pistons and damage the engine. If high-quality fuel and oil are used, the engine can last up to 350,000 km; however, before reaching this milestone, it will be necessary to replace almost all gaskets and seals.

Nissan HR16DE

The 16-valve engine from Nissan has its pedigree dating back to the 1990s, when it was installed on many models of the company. During this time, the engine has managed to get rid of its childhood diseases and, to date, has shown itself at its best. It is endowed with sharp traction on topsides and perfectly pulls from idle rpm. For a small-capacity C-class, it is sufficient even for drivers with racing ambitions, within reason, certainly. The engine likes high revolutions, but it sinks in daily traffic jams. If driving for a long time at low revolutions, jostling in car queues, piston rings can wear down. Therefore, from time to time, it is necessary to burn out the engine, having rushed along the highway at revolutions above average. As for the rest, the engine is exemplary reliable. Even a timing chain will have to be updated only after 250,000 km. The engine’s lifetime reaches 350 thousand km.

Mitsubishi 2.0 4B11.

This motor has been in production since 2005. It has been put in many models, particularly in Outlander and tenth Lancer. The engine is all aluminum, with cast-iron liners pressed into the block, a 16-valve head, and hydro-compensators in the valve train. The variable valve timing system is available in two versions: only on the intake valves or on both shafts, and the timing mechanism is a chain.

The reliability of this “four” is largely due to the simplicity of design, without new-fangled, but capricious frills. The quality of the assemblage and metal is quite decent. The engine arrives at the repair area primarily due to the natural wear of the cylinder-piston group. And it can happen to 300-400 thousand km. Additionally, it has a repair size, and original parts can be purchased separately.

Mazda 2.0 Skyactive-G

Gasoline “four” from Mazda in our rating is rather an exception than a rule. The engine is simply stuffed with innovative technologies – except that there is no turbocharger. Of the technical delicacies we should mention direct injection, the system of phase change in the timing chain mechanism on both shafts, came from the motorsport exhaust manifold, working under the scheme 4-2-1, as well as a record for modern gasoline engines compression ratio 14:1. In addition, the engine simultaneously works on the Atkinson cycle and Otto, which allows for high power (150-168 hp and 208 Nm) and environmental friendliness with a record low fuel consumption (4.9 l/100 km according to the manufacturer).

But the most important thing is that the Skyak four turned out to be extremely reliable. However, the flip side of the medal is its insistence on the quality of fuel and oil. At the same time, it is necessary to constantly monitor the level of liquid lubrication. Since the “Skyactive” motors are generous in oil consumption, their deficiency can lead to a breakdown.

The engine of this series has been in production since 2011, and to date, there have been no significant issues; those that have arisen have been promptly addressed. Some machines with this engine have run more than 250,000 km, and are still in operation. However, the maintainability of the engine is not the highest, and with spare parts can be difficult.

Renault 1.6 K4M

The Renault K4M engine has been part of its family tree since the 1990s and has undergone minimal changes since then. And the modern trimmings – twin-shaft timing and hydrocompressors in the valve train. The cylinder block is made of cast iron, and the piston group is time-tested and not prone to oil consumption. The engine has excellent low-end traction and a fairly modest fuel appetite and is indifferent to slight overheating. With the use of quality consumables and the timely replacement of key components, such as the timing belt with rollers and the coolant pump, the engine demonstrates remarkable reliability.

True, the masters call the engine snotty – after 150,000 km, the valve cover gaskets, oil seals, and seals of crankshaft and camshafts start leaking. The engine electronics occasionally malfunction – specifically, the sensors, blocks, and ignition coils malfunction. And that’s, perhaps, all. After an overhaul, the K4M can easily run up to 400,000 km. And the cost for parts and work will be very modest.

Subaru 2.0 FB20.

The FB20 engine replaced the legendary EJ20 for its reliability back in 2010. All shortcomings of the predecessor were taken into account during the development of the new engine, including lightweight pistons, asymmetric connecting rods, and a redesigned cooling system. The engine is even more durable due to the use of timing chain instead of timing belt, and cast iron bushings are pressed into the aluminum engine cylinder block. But it was not without problems. The first copies had a defective cylinder block, which led to a sharp increase in oil consumption. But since 2013, this defect has been eliminated. Although it is recommended to carry a can of oil with you.

In general, the engine has proven to be as conditional as the EJ20. Although it is inferior to it in maintainability. Also FB20 like quality fuel and oil, as well as regular maintenance with an interval of 10,000 km, and better often. Spare parts are expensive, and there are few quality “non-original” parts on the market. But the engine life is approaching 400,000 km.

Toyota 2.0 3ZR-FAE.

This power unit from Toyota has inherited durability and reliability from its predecessor AZ series. At the same time, it got rid of the problems of thread weakness of the block. At the same time it became technically more advanced, slightly more powerful and more economical. The engine is for the first time equipped with the Valvematic system, which smoothly varies the height of the valve lift, appeared hydro-compensators and a system of dual variable valve timing on the intake and exhaust shafts (Dual VVT-i). It was the weak link. After 100-130 000 km mileage the phase change clutches were failing. Replacement, however, does not strike much on money – repair will cost about 25,000 rubles.

In general, the cost of original spare parts for Toyota is cheaper than most competitors, and the repair price is the lowest among the Japanese classmates. Engine life is about 350,000 – 400,000 km.

Honda 2.0 R20A

Another Japanese engine Honda R20A has settled in the troika of leaders. It is reliable and quite simple in design, and it is still installed in some models of the company. It can be found in the past generations of Accord and CR-V of the last three generations. It has been available since 2005. The engine has good traction throughout the range and especially a powerful kick after 3,000 rpm. It is noteworthy that the engine “4” quickly accelerates up to 7000 rpm – the motorcycle experience in construction of automobile power units affects. The engine is fully “aluminum”, with a single camshaft that drives a 155 horsepower chain, which is quite decent for that time. The i-VTEC system is responsible for phase adjustment. There are no hydro-compensators – it is necessary to adjust them every 45,000 km, although in fact the operation is required much more seldom – after 80-120 thousand km.

The engine resource is 350,000-450,000 km. The quality of parts manufacturing is higher than that of competitors. Here is just the repair dimensions for the engine are not initially provided. Parts for Honda engines are not cheap, so the overhaul is one of the most expensive among the “Japanese”.

1. “Light a cigarette” from a donor

The most reliable way to revive a car with a dead battery is to use the energy of a functioning car. For this purpose, it is necessary to place the second car side by side (directly “bumper-to-bumper”), open the hoods, and connect the batteries of both cars with wires. Make no mistake! 

The correct procedure is: 

• Turn off the donor’s engine and turn off the ignition.
• Connect the red wire first to the positive terminal of the donor, then to the discharged battery.
• Connect one end of the black wire to the “mass” of your car (for example, to the engine cylinder block or body) and the other end to the negative terminal of the donor.
• You can start the car. After starting, you must disconnect the wires strictly in the reverse order – this order will reduce the chance of a short circuit if the wires are handled carelessly.
• If the battery is dead on the road, “light from a donor” is the most reliable way. 
• Push or tow.

Both options are only suitable for cars with manual transmission and are based on the principle of turning the engine from the wheels. All you need is a second serviceable car and a strong rope, but two adults are enough to accelerate. Source https://rentalyagupo.com/

The procedure is as follows: 

• Connect the two cars with a tow rope, turn on the ignition, squeeze the clutch and engage the third gear without releasing the clutch.
• The towing driver should pull the rope, smoothly move off and accelerate the cars to a speed of about 20 km/h.
• The driver of the towed vehicle must release the clutch smoothly and, if successful, signal the master to stop.
• Approximately the same rules apply for helpers, but the speed will be lower, so several attempts may be necessary.

3. Use a rope or rope

A front- or rear-wheel drive car with a manual transmission can be started in another exotic way, relying on the strength of one person. You need a long flat rope and a jack.

Airing and blowing: how to drive in severe frosts

You need to fix the car with the parking brake, lift it with a jack on the side of one of the two drive wheels and turn the wheels out to the side.

Wrap a rope around the wheel so that by pulling the rope towards yourself you make the wheel rotate counterclockwise.

Put the car in third gear, switch on the ignition and try to spin the wheel with the rope.

If the engine can be started, the wheel will rotate on its own, and you will need to immediately engage the neutral gear. The axle differential will transmit all torque to the wheel hanging in the air, which prevents spontaneous movement. 4.

Use a battery charger or booster

Start-chargers come in a variety of types, from large industrial to compact pocket-sized boosters. The most powerful variants are connected to the mains, but can also work completely autonomously. It is enough to connect the device terminals to the battery, turn on the ignition and start the engine.

The pocket booster works the same way as a spare battery for a cell phone, and you need to charge it in advance. Such a device produces a high current, but for a long time its charge is not enough, so it can help only in cases where the car is serviceable, and to start the engine is not enough at all. In addition, boosters can not always help with starting large-volume engines and diesels. Using it is just as simple: you need to connect the “crocodiles” booster to the battery terminals, turn on the ignition and start the engine.

In case the battery runs out, it’s a good idea to have a pocket booster with you 

5. Use a powerful battery charger

Remember the huge garage battery chargers? Such a unit can help, but there is one nuance: it will not be able to charge the battery quickly, but in a relatively short time it can transfer enough energy for a successful start.

The main thing to do is to set the charger to a high current of up to 10% of the battery capacity. For example, a 55 amp-hour battery should be charged with a current of 5.5 amps. Under these conditions, the vehicle battery will be charged in just 15 minutes.

Important: Charge the battery by disconnecting it from the vehicle’s onboard power system. In addition, this method of charging negatively affects the life of the battery.

6. Using the battery from a screwdriver

There are also more non-standard ways to start the motor. For example, if the battery of a screwdriver or other tool has a voltage greater than 12 volts, it can also be used to help.

The way to proceed is as follows: 

Connect wires to the battery terminals or make an adapter for standard wires from improvised materials.

Large starting current such battery is not able to provide, but for a few minutes, it can slightly replenish the charge of the car battery.

After 15-20 minutes try to start the engine. 

In a critical situation to recharge the battery will help the battery screwdriver or other power tools 

7. Warming the battery with water

Have you heard the advice, that the battery should be warmed up with a short light of headlights before start-up? Well, this is nothing more than a baize. But it is possible to warm the battery at home – it gives a noticeable effect in the cold season.

It is necessary to take off battery, take it home, and put it in the bathtub or deep basin which should be filled with hot water up to the level of the top cover of the battery. In 15 minutes the battery will be warm, and after half an hour of warming, even a nearly discharged battery will be able to give enough current to start the engine.

8. Use alcohol

The most exotic way to revive a dead battery involves the use of alcohol-containing liquids. These are poured into the battery banks and cause a chemical reaction. This method does not work with maintenance-free batteries.

It is best to use dry wine with a low alcohol concentration and no sugar. Stronger alcohol will have to be diluted. Thirty ml of wine is poured into each battery pack. The chemical reaction will lower the internal resistance of the battery, the battery voltage will become higher, and the motorist will have a chance to start the engine. Alas, after this procedure, the battery will have to be thrown away.

The green light, highlighting a small row of amber lights around the track, signifies the moment when a pair of dragsters starts. And so the two incredibly powerful, unusually elongated cars launch, leaving the flames behind them, with frantic acceleration. And there’s a good chance that one of them could take off with the slightest mistake in the aerodynamics calculation. And the 10,000 horsepower contributes to that perfectly. Acceleration to a hundred in less than half a second loads a dragster pilot up to 4G.

The distance at which dragsters start varies depending on the particular series of races. Most often it is 1,000 feet (304.8 m), but in different types of races it can be up to 800 meters.

The main factor that sets Top Fuel dragsters apart from other race cars is that they are considered the fastest and most powerful cars on the planet. In fact, just one of the eight cylinders in the engine produces about 1,000 horsepower – as much as a Formula One car produces in the entire engine. Use our source

All dragsters achieve tremendous power from engines of about 6.5 to 8.2 liters of displacement. Moreover, the maximum displacement set by the drag race organizers is 8.2 liters. No surprise there, is there?! But the superchargers and a special type of fuel make them capable of developing about 8,000 horsepower. However, according to some estimates, the power still reaches all 10,000 horsepower – and there are good reasons for such discrepancies and inaccuracies. The fact is that dragster engines cannot be measured with a dynamometer, a device that evaluates the power and torque of a car. Thus, the amount of power Top Fuel dragsters have is calculated using mathematical equations that can leave room for debate.

The engine before the dragster race

Dragster engines use, of course, not gasoline, not methane, and certainly not diesel. They need nitromethane, a special kind of fuel that gives off a lot of energy when burning – much more than gasoline. What’s more, the concentration and composition of the fuel is made specifically for drag racing. It’s a complex balance that requires fine-tuning and the car itself. And all this effort just to get racers going at previously unheard of speeds and acceleration as fast as possible through the damn quarter mile!

The people who build dragster engines – engineers, mechanics, and amateur drag racers all over the world – eventually came to the conclusion that a nitromethane mixture was the best fuel for these particular types of engines. Nitromethane is a dangerous volatile substance that is often used for pesticides, pharmaceuticals, heavy cleaning solvents, and even rocket fuel. Anyway, the Germans in the 1930s and the Americans in the 1940s independently discovered that nitromethane could also be used in racing cars. The results of such findings were often lamentable – racers were often killed by exploding race cars. But engineers didn’t stop and continued to do experiments on the use of nitromethane in internal combustion engines.

Exploding dragster engine

Nitromethane is very dangerous. If the dragster engine is not running properly, and the unburned fuel is not completely burned in the engine during the first combustion cycle, it can explode with force strong enough to rupture the cylinder head or engine block. Nitromethane can also explode from a little heat or shaking. This is one explanation for why dragsters have a lot of flame coming out the back of their exhaust pipes – unburned fuel heats up as it comes out through the exhaust system and ignites when it comes into contact with the atmosphere.

An engine that runs on nitromethane tends to have much less compression than a gasoline engine (which at first glance is counterintuitive). But the explanation for this is that, unlike gasoline, nitromethane itself contains oxygen, so the engine doesn’t need as much air for the combustion cycle, allowing it to run at lower compression. However, the engine and its components are under such tremendous pressure that all connections must be carefully checked on a regular basis.

Currently, Top Fuel dragsters run on a mixture that is 90 percent nitromethane and 10 percent methanol. Methanol helps suppress detonation, which makes the fuel more stable.

Nitromethane can also be mixed with a third substance other than methanol to help increase its energy potential, but this tactic is banned by most race organizers. In part, such a ban is worthwhile because other fuel mixtures are more dangerous.

But there is no cooling system for dragster engines at all. The engine simply does not have time to heat up to destructive temperatures in a short period of time. The absence of a cooling jacket inside the engine block provides a significant increase in its durability.

The dragster cars start and reach 100 kilometers per hour in less than half a second, and 160 kilometers per hour in less than a second. This makes them the fastest accelerating cars in the world, as well as the fastest in principle. Power from the engine reaches the wheels in a fraction of a second — about 15 fractions of a second, to be exact. At launch, dragster drivers endure a load similar to astronauts during the launch of a spaceship. And almost as quickly they have to stop. After crossing the finish line, the driver presses a button that deploys two parachutes behind the car, and the intense wind resistance slows the car with minimal risk of additional mechanical damage.

Drag racing spectators are advised to wear hearing protection when watching a dragster race. The noise made by the engines can even destroy weak eardrums when they are close to a dragster running at maximum speed.

Dragsters are essentially considered the loudest race cars, in part because of the way the engine is mounted. If that engine were at least under the hood, as in a regular car, at least there would be some insulation to muffle the sound. But alas, cars don’t even have mufflers.

One drag race organizer, the NHRA, once let a team of seismologists stand on the starting line to measure seismic activity levels, just as if they were measuring an earthquake. The measurements produced two machines that produced activity rated at 2.3 on the Richter scale. This is equivalent to a minor earthquake, which many people feel.

As for the sonic power of dragsters, experts estimate that these cars can produce a roar of over 150 decibels, a level that can cause physical damage to the eardrum. By comparison, a typical rock concert generates about 100-120 decibels.

To date, there is no sign of drag racing’s popularity declining anytime soon. In fact, within just the last few years, the cars themselves have become even more powerful.

Even more about the engines of dragsters – they live about 3 minutes, after which a whole reconstruction awaits them – very much – from spark plugs to gaskets are changed.

And finally, the most interesting facts about dragsters, which are hard to believe at once.

At maximum load, the dragster’s engine consumes more than 5 liters of nitromethane per second. By comparison, a huge Boeing consumes about the same amount.

The spark plugs in dragster engines are disposable. Moreover, they do not live to the end of a 3-minute race. First the engine warms up, then it lapping takes place, and at this time the plugs are far from being worn out. At the end of the 3-minute race, in the last 5 seconds from the start to the moment of crossing the finish line, the plugs are already killed in the first half of the race, and the ignition is due to compression.

The tires of the dragster’s driving wheels usually increase in diameter to the end of the race by 15-25% due to heat and wear. The tires, by the way, are disposable, as well as the plugs.

The power of a standard V8 engine from some sports car isn’t enough to even turn the dragster’s engine.

The dragster will reach a speed of 450 km/hour faster than you will read this fact.

On average, one dragster run costs its team about $5,000.

The dragster doesn’t have a gearbox, and a four- to five-speed clutch transfers torque from the engine to the wheels.

-New color developed with Mazda’s proprietary Takuminuri painting technology-

HIROSHIMA, Japan, Nov 15, 2022 – (JCN Newswire) – Mazda Motor Corporation has applied its proprietary painting technology Takuminuri(1) to develop a new special color Artisan Red Premium. This color will be introduced as a premium highlight for vehicles in our current lineups as well as forthcoming releases in our Large Product group.

Mazda believes color to be a crucial element of what gives form to a vehicle; thus, we are focusing our efforts on developing colors that accentuate a dynamic and delicate expression in line with the Kodo – Soul of Motion – design theme. Artisan Red Premium, the fourth Takuminuri color, was developed to extend the range of how the world views red, one of the colors symbolizing Mazda, as a culmination of the Takuminuri evolution to mark the 10th year since the first color Soul Red Premium was released.

Artisan Red Premium conveys the connotation of a red color created by skilled artisans. This extraordinary red produced by Mazda designers, engineers and other artisans manifests a mature outlook that is more refined and sophisticated than previous special colors. The concept underlying design was to create the red found in a mature wine made with unsurpassed craftsmanship. Artisan Red Premium accentuates the strength and beauty of form that takes shape as highlights hit by light portray a fine-grained transparent red shining brightly and dominant shade produces a profound depth and richness, rendering high contrast.

Also, similar to Soul Red Crystal(2), Artisan Red Premium is comprised of three layers: a clear layer, translucent paint layer, and a reflective/absorptive layer. It combines an outstanding aesthetic appearance with a reduced environmental footprint. For the translucent paint layer, a high-chroma pigment is employed that people perceive to be the reddest of reds, a pigment also used for the Soul Red Crystal. For the reflective/absorptive layer, we applied a technology that more smoothly aligns aluminum flakes at regular intervals. This was also leveraged for the third Takuminuri color Rhodium White Premium. In addition, we improved on the jet-black pigment, which renders shade in the second color Machine Gray. This combination of technologies developed over a period of 10 years conveys brightness in highlights produced by strong reflection and the richness of shades created as light is soundly absorbed so as to achieve a balance between transparency and a mature profoundness.

In the belief that “color is an element of form,” Mazda will continue to pursue new color expressions and painting technologies to enhance the attractiveness of our products, aiming to be a company that shares a special bond with its customers.

(1) Takuminuri, which translates as “Artisan coloring,” is Mazda’s painting technology that reproduces a precise, high-quality paint finish as if applied by the hands of a skilled craftsman along the automobile mass production line.
(2) Soul Red Crystal is a further refinement of Soul Red Premium and a special paint color developed with the Takuminuri painting technology.
