What attracts diesel
Modern diesel cars are attractive for their ability to develop greater thrust at low revs than especially good for drivers who do not like to shift gears too often. Most manufacturers offer diesel engines with turbocharging to give the owner the opportunity to experience the charm of the most high-end machines.
If you're thinking about switching to diesel, but do not know how to take care of him with his hands, then immediately say that keep diesel in good condition just as easy petrol engine, despite their differences. We offer you a brief guide to buying, operating and maintenance of diesel.
Mechanisms of petrol and diesel engines are not much different. The basis of both engines put a four-cycle combustion, but it happens they have completely different ways.
While gasoline engines have fuel mixture is ignited by spark ignition, diesel fuel ignites resulting in a very high compression.
When the gasoline engine sucks air and gasoline to the first stroke, diesel sucks only air which is compressed to such an extent that its temperature rises to 800 ?� C hot air ignites the diesel fuel, which is injected into the combustion chamber of the cylinder shortly before the piston reaches BMT on the compression stroke. Since the degree of compression of diesel engines at twice higher than that of gasoline engines, the fuel injection must take place under very high pressure, so that it flew into the combustion chamber and the jet fuel retained give it form. Due to increased demands on injection, high pressure fuel pump of a diesel engine is extremely high-precision assembly manufactures.
On older models of diesel engines commonly used in-line multiplunger high pressure fuel pumps. Now most modern diesel engines are used more complex rotary pumps with a constant feed of fuel as they work better at higher engine speeds. Modern diesel engines use electronic controls fuel metering to achieve combustion of the process close to ideal. Many are equipped with diesel engines even converters to clean exhaust fumes.
There are two types of diesel engines, and the difference between them is that in them the fuel is combusted. Some use direct fuel injection. The very name indicates the forward direction of the fuel in the combustion chamber cavity. Although this method is very effective injection, its drawback is a lot of noise and jitter. For this reason, direct injection diesel engines remained only used on trucks. However, diesel engines improved designs these drawbacks to a large extent eliminated, and the majority of car manufacturers offer high performance diesel engines with direct injection.
In other diesel engines that do not use direct fuel injection, combustion chamber to create a small additional chamber into which fuel injection occurs. Have the camera on the opposite side of where the nozzle and direction of movement of the injected fuel it. This constructive method allows you to raise the engine speed, but it has to pay for some loss of power.
