Systems of preheat and heating of fuel of the diesel engine

Preheat system - the general information

The glow plug is screwed in the chamber of combustion of each cylinder. Candles heat up an electric current before start, during start and some time after engine start. Food giving on glow plugs the module of management of heating (supervises engines of 1.7 l and 2.0 l of Y20DTL) or ECM (engines of 2.0 l, кромеY20DTL).

On the dashboard the corresponding control lamp (is highlighted see. Head the Operation manual), - after a signal will go out, the engine it is possible to start engine start. The supply voltage continues to stand out on candles within several more seconds after shutdown of a control lamp. If attempts of start of the engine it was not undertaken, the special timer disconnects food giving on candles in order to avoid a podsadka of the storage battery and an overheat of candles.

In system the function of post-heating providing giving of a food on candles during even some time after implementation of start of the engine is put also, - duration of a delay of shutdown of candles is regulated by the management module, depends on temperature of the engine and can make till 6 minutes.

The fuel filter is also equipped with the system of heating providing optimization of process of combustion at the expense of prevention of "parafinirovaniye" of diesel fuel. The heating element is established between the fuel filter and its case. A food on heating of fuel moves on commands of the module of management through built in in the filter case the thermosensitive sensor switch. Tension moves on TAN of the filter at temperatures below 5°C and is disconnected at temperatures above 16°С.
