A glow plug is screwed into the combustion chamber of each cylinder. Spark plugs are heated by electric current before starting, during starting and for some time after starting the engine.
The corresponding control lamp lights up on the instrument panel (see chapter Controls and methods of operation at the beginning of the guide), - after the signal goes out, the engine can be started to start the engine. The supply voltage continues to be supplied to the candles for a few more seconds after the control lamp is turned off. If there were no attempts to start the engine, a special timer cuts off the power supply to the candles to prevent the battery from being drained and the candles to overheat.
The system also has a post-heating function that provides power to the candles for some more time after the engine is started - the duration of the delay in switching off the candles is regulated by the control module, depends on the engine temperature and can be up to 6 minutes.
The fuel filter is also equipped with a heating system that optimizes the combustion process by preventing «waxing» diesel fuel. The heating element is installed between the fuel filter and its housing. Fuel heating is powered by the commands of the control module through a temperature-sensitive sensor-switch built into the filter housing. Voltage is applied to the filter heating element at temperatures below 5°C and switched off at temperatures above 16°C.
