General information

The models of cars described in this manual are equipped with system of consecutive multipoint injection of fuel (MPFI). The system uses clock pulses for ensuring consecutive injection of fuel directly to the inlet port of each of cylinders. Work of injectors is controlled by the power module of management (RSM). RSM traces various parameters of the engine and on the basis of the analysis of the obtained information defines exact amount of fuel which has to be injected in a certain sequence into inlet ports of the engine at present.

All models are equipped with the electric fuel pump installed in the fuel tank. For ensuring access to the above-mentioned pump the fuel tank needs to be removed. The fuel level sensor is built in directly the fuel pump and is taken from a tank similarly.

Sistema of production of the fulfilled gases consists of a final collector(s), the catalytic converter, exhaust pipes and the muffler. Each of the listed components can be replaced in an individual order. More detailed information on the catalytic converter is provided in the Head Sistemy of decrease in toxicity of the fulfilled gases and engine management.
