GENERAL INFORMATION

On the cold engine the spontaneous ignition temperature by compression is not reached, therefore the engine is necessary for warming up.

For this purpose in each chamber of combustion are screwed in on one glow plug. The glow plug consists of the case with a vpressovanny heating core. As soon as tension moves, within several seconds the winding of a heating core heats up to +850 ° With thanks to what warming up time before start-up will be reduced till 5 seconds. After the control lamp of system of preheat on a guard of devices will go out, it is possible to start the engine.

Duration of preheat as well as automatic support after start (approximately within 20 seconds), is regulated by the preheat relay DDE monitor.
