Ignition system

The system of ignition develops in each cylinder of the engine during the necessary moment of time a spark. The spark ignites fuel - an air mix. In the ignition coil for this purpose tension of the battery 12 B will be transformed to tension over 30000 Century. The diesel engine of system of ignition has no, as thanks to high extent of compression air heats up so that injected fuel ignites.

All carburetor engines and the injector engine in volume of 1,4 l are equipped with transistor system of ignition. Engines with system of injection of fuel are equipped with electronic system of ignition. The system of ignition consists from:

  • spark plugs
  • ignition cables
  • ignition coils
  • the ignition distributor with a begunok, the sensor of the Hall and a monitor

Developed in the ignition coil tension moves through a begunok of the distributor and ignition cables to the corresponding spark plugs. On electrodes of candles the spark which ignites fuel - an air mix in cylinders slips. The ignition moment at increase in number of turns should be displaced automatically in the direction of early ignition. This shift in transistor system of ignition is carried out in the distributor at the expense of centrifugal грузиков and at the expense of vacuum (a vacuum hose from an inlet pipe to the ignition distributor). In electronic system of ignition the microprocessor built in the distributor calculates the optimum moment of ignition depending on number of turns and degree of loading of the engine. Besides, the processor provides ignition shutdown. The problem of the distributor consists in distributing an ignition current in the set order between cylinders, and by means of the sensor of the Hall to issue information on number of turns and the ignition moment in a monitor ignition.

Engines with system of injection of fuel are equipped with electronic system of ignition. The monitor ignition is incorporated with a monitor injection. The microprocessor operates the ignition moment on the basis of the field of characteristics written down in his memory.

In parametrical system of ignition the optimum moment of ignition depends on an engine condition. As parameters the number of turns, temperature of the engine and loading degree (the provision of a butterfly valve and amount of soaked-up air) serve. It is understood as instant loading of the engine as there is a difference if the car with number of turns of 4000 rpm rises uphill or climbs down a mountain.

Necessary characteristics for system of ignition are defined in the course of test at the stand and then coordinated with tests in actual practice so optimum value of fuel consumption, composition of the fulfilled gases and rideable qualities is reached. The values defined thus are written down in memory of a monitor.

At works on system of ignition it is necessary to observe security measures.
