On the cold engine the spontaneous ignition temperature only at the expense of compression therefore preheat of a fuel mix is necessary is not reached.
For this purpose the glow plug is screwed in each chamber of combustion. The glow plug generally consists of the case with the heating core pressed in it. When giving tension the heater winding in a core within several seconds is warmed up to temperature over +850 ° With thanks to what duration of a warming up before start seldom lasts more, than 10 seconds. At attenuation of a control lamp of a warming up on the dashboard it is possible to make engine start.
For acceleration of a warming up of the engine heat proceeds and after its start. Duration of preliminary heat is defined by the control unit depending on temperature of cooling liquid. The control unit is behind the central console under an air line.
Information on temperature of the engine arrives in the control unit from the sensor of temperature of cooling liquid. On the basis of the received data the control unit defines duration and current size.
