Preheating device (Mitsubishi Lancer 3)

In a cold engine, it is impossible to achieve the ignition temperature of the fuel through compression alone, so the engine must be warmed up.

For this purpose, a glow plug is screwed into each combustion chamber. The glow plug consists essentially of a housing and a heating rod pressed into it. As soon as voltage is applied, the heating coil in the heating rod heats up to a temperature of 850°C within a few seconds, due to which the warm-up period before starting rarely lasts more than 10 seconds. After the warm-up indicator lamp on the instrument panel goes out, the engine can be started.

The warm-up duration is regulated by the electronic control unit, located in the passenger compartment next to the glove compartment on the right. The engine warm-up control unit receives information about the engine temperature from the coolant temperature sensor. Based on the information received, the control unit determines the duration and magnitude of the warm-up current.
