Diesel engine

Diesel engine

is an internal combustion engine in which:
– air is compressed, the temperature of which rises to 600-700 ° C.
– the fuel ignites when it comes in contact with hot air.

Diesel engine

Diesels are placed only on trucks.

Many modern cars have diesel engines, and, for example, in Europe people even prefer diesel engines to gasoline engines.

Diesel engine is less powerful than gasoline.

With the current level of technology, it often turns out to be the other way around. The modern diesel engine can outperform the gasoline engine in power, not to mention the torque, which provides the flexibility and convenience of controlling acceleration.

Diesel engines are effective only for large volumes.

For a diesel engine, just like for a petrol engine, there are no volume restrictions. Now cars with volume of the diesel engine 1,1 are issued; 1.3 liters, and even motorcycles with a diesel engine capacity of 0.6 liters.

Even if the diesel is more powerful, due to its weight, it loses in response to the petrol characteristics.

Now the same materials are used for diesel engines as for petrol ones, so they are not much heavier.

The diesel engine gets worse in winter.

If you do not save money on glow plugs and winter diesel fuel, then it will start in any frost with the same ease.

The diesel engine with the turbine spends more fuel.

Paradoxically, a turbine in a diesel engine, unlike a gasoline engine, reduces fuel consumption. This is due to the sharply increasing torque, which allows you to drive the car more quietly.

Diesel engine

The diesel engine must be heated for a long time.

If the diesel engine is warmed up regularly, the remainders of carbon deposits and resins remain on the valves, which, if accumulated, can lead to a loose fit of the valve to the seat and even its stopping. But, nevertheless, turbodiesels need a short warm-up at idle to avoid breakage of the turbine.

Diesel engine is much more difficult to maintain and repair.

The diesel engine is much simpler in its design than the petrol engine, since ignition does not occur from the spark produced by the spark plug, but from the compression of the mixture in the cylinder. And since simple designs are always more reliable, then breakdowns of this type of engine occur much less often. In maintenance and repair, diesel engines are also much easier for obvious reasons.

The diesel engine is extremely noisy.

A diesel engine equipped with a good muffler and a modern intake system works a little louder than gasoline, but in most cases, the sound of modern gasoline and diesel engines is almost impossible to distinguish.

Any diesel requires good fuel.

First, many diesel engines, especially atmospheric ones, are absolutely not demanding on fuel. And secondly, even for the most fanciful diesel, you can put a filter-water separator and a filter of solid particles, which will fill the car with fuel of any quality.

Gasoline engines are still more reliable – they are better tested.

This is not true. Diesel engines on average have a resource of 40-50% more than a gasoline engine.

Diesel engine

In diesel it is useless to use sophisticated electronics.

The diesel engine allows the use of any complex systems in it. So, in a modern diesel engine, such systems as electronically controlled jets, a common common rail and common railroad fuel rail, and others are used.

It is not possible to boost the diesel engine.

Yes, diesel engines are less amenable to tuning than gasoline engines, but raising the power by 1.5 times without a special increase in fuel consumption is still possible.

Automatic transmission and diesel are not compatible.

The diesel engine is docked with an automatic transmission even better than a gasoline engine due to the higher torque that better drives the torque converter.

The exhaust of a diesel engine is more polluting.

With the use of catalytic converters, exhaust gas recirculation and particulate filter, the exhaust of a diesel engine can meet the most stringent environmental standards.

Diesel car is cheaper than gasoline.

With an equal level of equipment, a car with a diesel engine will cost more than a petrol engine due to the use of more expensive electronic and cleaning systems, but its operation will be cheaper.

The vibration of the diesel is too high.

With an even number of cylinders in one row, the vibration load of the diesel engine is quite acceptable, but if on the contrary – this statement becomes true.

Diesel engine

The diesel engine is filled with the same oil as in the gasoline.

For diesel engines, it is better to use special oil, and it is worthwhile to carefully study for which types of diesel engines it is intended.
