7.3. Work of a control system as the engineThe control system of the engine operates system of ignition and system of injection of fuel.
The fuel pump shipped in a fuel tank, submits fuel to a fuel highway through the fuel filter. Pressure of fuel in system copes a pressure regulator. He allows surplus of fuel to come back in a fuel tank at pressure excess in system. The fuel highway is the tank for atomizers which inject fuel into inlet channels of cylinders of the engine. In the engine the distributed system of injection of fuel is used, at which atomizers inject fuel independently from each other. The block operates work of atomizers, changing duration of an impulse – an interval of time, during which the atomizer is opened to provide giving of richer or poorer gas mixture.
Air passes through the air filter, a measuring instrument of the expense of air and throttle заслонку to inlet channels of cylinders. On the basis of the information from a measuring instrument of the expense of air and gauges the management block regulates time and quantity of injected fuel according to the measured quantity of air and frequency of rotation. The the atomizer is longer open, the more fuel is injected.
Additional gauges hand over the information to the management block about temperature of a cooling liquid and air arriving in the engine, and on models with catalytic neutralizer – about the oxygen maintenance in the fulfilled gases.
The filter with the activated coal interferes with penetration of harmful steams of fuel from a fuel tank in atmosphere. Fuel steams collect in the canister with the activated coal – an adsorber and at engine work дожигаются in engine cylinders.
The memory in the management block distinguishes the appeared malfunction and writes down it. At failure of the important gauge the management block is switched to the emergency program that the engine continued to work, though and with smaller efficiency.
The ignition system creates in each cylinder of the engine at a given time the spark category which ignites the compressed gas mixture.
