System Multec – incorporated system of ignition and fuel injection, also includes the catalyst, a control system of allocation of steams of fuel and system of repeated burning of the fulfilled gases.
The fuel pump shipped in a fuel tank, submits fuel from a tank to a fuel atomizer through the filter. Pressure of fuel in system copes a pressure regulator. The regulator allows surplus of fuel to come back in a fuel tank at pressure excess in fuel system.
The electric control system consists of block ECU together with following gauges:
All information from gauges is analyzed by block ECU, and on this basis the block defines a corresponding corner of an advancing of ignition and structure of a fuel mix. The block operates a fuel atomizer, changing width of an impulse, that is an interval of time, when the atomizer is opened to provide richer or poorer fuel mix.
Block ECU also supervises idling turns. For this purpose there is the step-by-step engine operating position throttle заслонки.
Block ECU also operates structure of exhaust gases and a control system of allocation of steams of fuel.
If there is an error in any of the data received from gauges, ECU enters into a way of the doubler. In this case block ECU ignores a wrong signal of the gauge and accepts preliminary programmed value which allows the engine to continue work, though and with smaller efficiency. If ECU enters into a way of the doubler the alarm system lamp on combinations of devices and damage will light up it will be written down in memory ECU. After that it is necessary to conduct full test of a control system by the engine, using the special electronic diagnostic test bed which simply joins in a diagnostic socket of system. The socket is located behind the central console. Thus for access to it it is necessary to remove decorative furnish in front of the lever of a manual brake.
