1.44.1. 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 we will tell that at once 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 chetyrekhkotaktny 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 VMT on a compression step. As extent of compression at diesels twice above 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 high-precision produced knot
On old models of diesels line multiplunger fuel pumps of high pressure on the majority of modern diesels were usually used Now 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 that as in them there is a fuel combustion. In one the direct injection of fuel the name is used indicates the direct direction of fuel in a combustion chamber cavity Though this method of injection is very effective its negative sides strong noise and unevenness For this reason are the direct injection remained only on the diesels used by trucks However on diesels advanced designs these defects considerably are 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 turns of the engine but to pay for it it is necessary some loss of power
