System of preheat of the diesel engine For achievement of necessary temperature of ignition compressed in cylinders of the cold engine of an air and fuel mix the system of a preliminary incandescence is used. The special candle consisting of the case with vpressovanny in it by a heating core is rolled in the chamber of combustion of each of cylinders, created by two spirals: heating and adjusting. After tension giving the heating spiral in a core heats up within several seconds to temperature + 850°С, thus a current, passed through a candle reaches 30А. With increase in extent of warming up increases and resistance filched that promotes decrease in a current to 15-25 A.Po's value shutdown of a control lamp of system of an incandescence on the dashboard dies away it is possible to carry out start the engine. Time spent for a preliminary warming up of cylinders no more than 10 with also is regulated by the special relay and the module of engine management (ECM), via the sensor of temperature of cooling liquid (ECT) receiving information on the current temperature of the engine. On the basis of the analysis of the received data of ECM exercises administration of duration of functioning of system of an incandescence and a working current of heating.
