Systems of ignition, preheat and engine management The basic data and security measures The ignition system provides ignition submitted to chambers of combustion of cylinders of petrol engines of an air-fuel mix. For formation of a spark of demanded intensity 12-volt pressure of an onboard network will be transformed in ignition coils to high-voltage pressure (30 000). The electronic system of direct ignition is an integral part of a control system of the engine. Its basic working components are candles and modules of ignition with the built in coils. Distribution of giving В/В of pressure to spark plugs the electronic control block (ECM) operates. Manual adjustment of the moment of ignition is not made, - at infringement of demanded installations it is necessary to make replacement of the failed components. Elements of management of system of ignition are not subject to deterioration and regular service do not require. According to the maintenance service schedule (see the Head of Adjustment and car routine maintenance) 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 confident ignition of diesel fuel. As heating elements candles накаливания which work the corresponding electronic block operates are used. The basic data on work and gauges of systems управлениядвигателем and fuel injection are stated in the Head of the Power supply system and release of the fulfilled gases. Schemes of work to control systems of engines are resulted on illustrations. Control system of petrol engines (Trionic T7)
