Air pre-heating device

In a cold engine, the self-ignition temperature is not reached only due to air compression by the piston, therefore, additional air heating is required.

For this purpose, a glow plug is installed in each combustion chamber. The glow plug has a casing with a heating coil. When voltage is applied to the candle, the coil heats up to a temperature of +850°C for no more than 10 seconds. If the preheat warning light on the control panel goes out, the engine is ready to start.

The duration of preheating is regulated by an electronic control unit located in the engine compartment on the right at the holder above the wheel casing, looking in the direction of travel.

The control unit receives data on the temperature of the coolant from the corresponding sensor. The control unit decides, based on the data received from the sensor, how much time and what strength of current is required to heat the air with glow plugs.
