- oxygen sensor or lambda probe (before and after the
neutralizer);
- absolute pressure sensor (dilution);
- phase sensor;
- sensor of detonation;
- air temperature sensor in the intake manifold;
- the speed sensor of the car;
- sensor of the quantity of gases submitted by the system of
recirculation;
- accelerator pedal position sensor;
- position of brake pedal position sensor;
- sensor of the position of the clutch pedal;
- pressure sensor of motor oil;
- motor oil level sensor;
- pressure sensor of the power steering;
- pressure sensor freon.
Depending on the signals of the sensors (quantity, pressure,
temperature of the suction air, the temperature of the cooling
fluid of the engine, mode of operation, etc.), the electronic
control unit calculates the amount of fuel currently required and
controls the actuators. The most common executive
mechanisms of the gas injection system are:
- nozzles;
- relay fuel electric pump;
- idle speed regulator;
- adsorber valve;
- exhaust gas recirculation valve;
- coils of ignition system;
- relay fan cooling system;
- compressor air conditioner relay;
- throttle valve drive motor;
- thermostat of the cooling system;
- valve of control of catches of an inlet collector.
