System of injection of fuel of the petrol engine The general data and security measures The system of electronic control by engine work regulates process of distribution of fuel and process of ignition of a fuel mix. The electronic control system allows:
The engine management block represents the small, high-speed computer. He establishes optimum time of ignition, the moment of injection of fuel and quantity of injected fuel. Thus there is a coordination of action of the block of management with other systems of the car, for example, management of a transmission or blocking from stealing. Elements of system of ignition and injection keep for a long time the working capacity and practically do not demand service. Within the limits of maintenance service carrying out it is necessary to make only replacement of an element of the air filter, and also to replace spark plugs. More serious works on adjustment and repair can be made only by means of special devices. Security measures at work with system of injection of the petrol engine
