Chevrolet Aveo engine control system

Chevrolet Aveo engine diagram - Chevrolet Aveo engine control system consists of the gauges giving the developed information on a condition of systems of the engine, an electronic control package and executive gears.

The gauge of absolute pressure of a collector defines changes of pressure in an intake manifold, growing out changes of loading on the engine and changes of speed of the car.

The cooling fluid temperature detector is the resistor with the negative temperature factor of resistance established on a water jacket of the engine. At low temperature the gauge has high resistance while at a heat resistance decreases.

The gauge of position of a throttle is a potentiometer connected to shaft of a throttle valve on the case of a throttle valve.

The detonation gauge finds out an inadmissible detonation of the engine. The gauge is established on the block of the engine about cylinders. The gauge makes an output voltage of alternate current which increases in process of detonation increase. This signal goes on a control package the engine which regulates distribution of ignition for detonation drop.

The system of direct ignition works by means of a magnetic sensor of position of a bent shaft.

The gauge of position of a cam shaft sends signal on a control package the engine. ЕСS uses this signal as a synchronising impulse for start of injectors in corresponding sequence.
