0a910c3c What attracts the diesel with?


Modern diesel cars are attractive by the ability to develop the big force of draft on small turns, than are especially good for the drivers who are not liking to switch too often transfers. Most of manufacturers offer diesels with a turbo-supercharging to give to the owner the chance to feel most all charm of the high-class car.

If you think of transition to the diesel, but do not know how to look after him the hands, then at once we will tell that is not more difficult to support the diesel in good shape the petrol engine, despite their distinctions at all. We offer you the short guide to purchase, operation and service of the diesel.

Mechanisms of the petrol and diesel engine a little in what differ. The four-cycle cycle of combustion of fuel is the basis for operation of both engines, but there is it at them in absolutely different ways.

While at petrol engines fuel-air 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 sucks in only air which compresses to such an extent that its temperature rises to 800 °C. The heated air sets fire to diesel fuel which is injected into the cylinder combustion chamber shortly before the piston reaches BMT on a compression step. As extent of compression at diesels is twice higher, than at petrol engines, the injection of fuel has to happen under very high pressure that it flew in the combustion chamber, and the stream of fuel kept the form given it. Owing to the increased requirement to injection, the fuel pump of high pressure of the diesel is especially vysokotochno the produced knot.

On old models of diesels line multiplunger fuel pumps of high pressure were usually used. Now on the majority of modern diesels use more difficult rotor pumps with constant supply of fuel as they work at high turns of the engine better. In modern diesels electronic control systems of dispensing of supply of fuel for achievement of course of process of combustion close to ideal are used. Many diesels are even equipped with converters for purification of exhaust gases.

There are two types of diesels, and distinction between them consists in how in them there is a fuel combustion. In one the direct injection of fuel is used. The name indicates the direct direction of fuel in a combustion chamber cavity. Though this method of injection is very effective, its negative sides are strong noise and unevenness. For this reason the direct injection remained only on the diesels used by trucks. However on diesels of advanced designs these defects are considerably eliminated, and most of producers of cars offer highly effective diesels with direct injection.

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