The pre-heater serves to preheat the car engine before starting at low ambient temperatures and helps to reduce the wear of cylinders and pistons.

The set of starting heater includes a boiler filled with coolant, a fuel tank, an electromagnetic valve, a fan with an electric motor, a glow plug, and a control panel.

Before starting the engine, the solenoid valve opens and spark plugs ignite. Air is supplied to the boiler from the fan. Hot gases passing through the gas pipelines heat the liquid, and at the same time, the nozzle from the boiler is directed to the oil pan, heating the oil in it. The coolant heats up in the jacket and cools the cylinder block.
