Modern diesel cars are attractive ability to develop the big force of draught on small turns, than are especially good for the drivers who are not loving too often to switch transfers. The majority of manufacturers is offered by diesel engines with a turbo-supercharging to give the chance to the owner to feel most all charm of the high-class car.

If you think of transition to a diesel engine, but do not know how to look after it the hands, at once we will tell what to support a diesel engine in a good condition is not more difficult at all than the petrol engine, despite their distinctions. We offer you a short management on purchase, operation and diesel engine service.

Mechanisms of the petrol and diesel engine a little than differ. The four-cycle cycle of burning of fuel is put in a basis of work of both engines, but there is it at them in absolutely different ways.

While at petrol engines топливовоздушная the mix ignites spark plugs, diesel fuel ignites as a result of very strong compression.

When the petrol engine soaks up air and gasoline on the first step, the diesel engine sucks in only air which is compressed to such degree that its temperature rises to 800 With. Heated air sets fire to diesel fuel which is injected into the chamber of combustion of the cylinder shortly before the piston reaches BMT on a compression step. As degree of compression at diesel engines twice above, than at petrol engines, fuel injection should occur under very high pressure that it flew in the combustion chamber, and the fuel stream kept the form given to it. Owing to an increased requirement to injection, the fuel pump of a high pressure of a diesel engine is especially высокоточно the produced knot.

On old models of diesel engines were usually used рядные многоплунжерные fuel pumps of a high pressure. Now on the majority of modern diesel engines apply more difficult роторные pumps with constant giving of fuel as they work at high turns of the engine is better. In modern diesel engines electronic control systems of dispensing of giving of fuel for achievement of course of process of combustion close to the ideal are used. Many diesel engines even are equipped with neutralizers for clearing of exhaust gases.

There are two types of diesel engines, and distinction between them consists in how in them there is a fuel combustion. In one direct injection of fuel is used. The name specifies in a direct direction of fuel in a cavity of the chamber of combustion. Though the given method of injection is very effective, its negative sides are strong noise and non-uniformity. For this reason direct injection has remained only on the diesel engines used by lorries. However on diesel engines of advanced designs these lacks appreciably are eliminated, and the majority of manufacturers of cars is offered by highly effective diesel engines with direct injection.

In other diesel engines which are not using direct injection of fuel, in front of the combustion chamber create the small additional chamber in which there is a fuel injection. Have this chamber on the opposite party from an installation site of an atomizer and a direction of movement of fuel injected by it. The given constructive method allows to lift engine turns, but to pay off for it it is necessary some loss of capacity.
