Description of construction

The system is multi-point sequential fuel injection (SFI) is based on a series of pulses and measuring the mass flow rate of air. The system supplies the engine cylinders toplivnovozdushnoy mixture of optimal composition. Intake air and fuel injection system works in conjunction with the electronic engine control. The latter includes various sensors, switches and the engine control unit (PCM). All sensors and switches are connected to the PCM, which processes the incoming data and calculates the timing and duration of opening of the electrically operated fuel injectors.

The basic requirement for optimal fuel delivery is determined by the data coming to the PCM from the air flow sensor. Other sensors and switches are used for the following measurements:

- Coolant temperature;
- Speed of the crankshaft of the engine;
- The oxygen concentration in the exhaust gases;
- Determining the position of the top dead point of the piston of the first cylinder in the compression stroke.

Various sensors and switches are informed of any changes to the operating conditions and sends appropriate signals to the PCM. This allows you to adjust the length of the opening of PCM (pulse duration) injectors and maintain the optimal mode for reducing the toxicity of harmful substances in exhaust gases and the operation of the engine under different operating conditions of the vehicle.
