The basis of the power supply system for each diesel engine is the fuel pump. Therefore, it is no wonder that the price of a new fuel pump sometimes even exceed the value of used cars. Therefore, the majority of motorists when replacing Fuel pump prefers toplevnomu restored high-pressure pump. The main functions of high pressure fuel pump – this is metered supply of fuel to the injectors, fuel pump on the responsibility to providing the start of injection, which is given by the angle of injection, like the corner of the ignition, if we draw an analogy with gasoline engines. Fuel pump for diesel engines use one of alternative distribution systems, fuel – it pumps the distribution or series type. High pressure fuel pumps in-line plunger is very cumbersome, and are mainly used for Car-heavy trucks.
On diesel engines of passenger cars (except for Mercedes-Benz) is generally used, fuel pump fuel injection pump camshaft tipa.Ustroystvo order to fuel a plunger received a pair of low pressure, Pumps are used pre-paging. In the distribution of such fuel pump mounted inside the pump housing. In-line, on the contrary, – passed out and driven from the camshaft diesel engine. High pressure fuel pumps can also be divided into two groups, depending on the mechanism controlling the amount of fuel supplied. It is electronic and mechanical fuel pump. It is clear that electronic monitoring takes into account a greater number of parameters to be more accurate and cost-effective. There are several types of fuel pumps, high pressure, which are used in cars are diesels.
