Systems of ignition, preheat and engine management Main data and security measures The system of ignition provides ignition submitted to chambers of combustion of cylinders of petrol engines of an air and fuel mix. For formation of a spark of demanded intensity 12-volt tension of an onboard network will be transformed in ignition coils to high-voltage tension (30 000 In). The electronic system of direct ignition is an integral part of a control system of the engine. Its main working components are candles and ignition modules with the built-in coils. Giving distribution In/in tension on spark plugs the block of electronic control (ECM) operates. Manual adjustment of the moment of ignition is not made, - at violation of demanded installations it is necessary to make replacement of the failed components. Elements of management of system of ignition are not subject to wear and regular service do not need. According to the maintenance schedule (see. Head of Control and routine maintenance of the car) it is necessary to make only replacement of spark plugs. The system of preheat of the diesel engine is intended for warming up of chambers of combustion for the purpose of sure ignition of diesel fuel. As heating elements the glow plugs which work the corresponding electronic block operates are used. The main data on work and sensors of systems an upravleniyadvigatel and injection of fuel are stated in Head of the Power supply system and production of the fulfilled gases. Work schemes to control systems of engines are provided on illustrations. Control system of petrol engines (Trionic T7)
