7.3. Systems of preheat and heating of fuel of the diesel engine
System of preheat - the general information
The glow plug is screwed in the combustion chamber of each cylinder. Candles heat up electric current before start, during start and some time after start of the engine.
On the dashboard the corresponding control lamp is highlighted (see the Head Governing bodies and methods of operation at the beginning of the Management), - after the signal goes out, the engine it is possible to start start of the engine. Supply voltage continues to be given for candles within several more seconds after shutdown of a control lamp. If attempts of start of the engine were not undertaken, the special timer turns off giving of food on candles in order to avoid replanting of the rechargeable battery and an overheat of candles.
In system also the post-heating function providing giving of food on candles during even some time after implementation of start of the engine is put, - duration of a delay of shutdown of candles is regulated by the module of management, depends on temperature of the engine and can make up to 6 minutes.
The fuel filter is also equipped with the system of heating providing optimization of process of combustion due to prevention of "parafinirovaniye" of diesel fuel. The heating element is established between the fuel filter and its case. Food on heating of fuel moves according to commands of the module of management via the thermosensitive sensor switch which is built in in the filter case. Tension moves on filter TEN at temperatures below 5 °C and is disconnected at temperatures above 16 °C.
