esilämmittin

An esilämmittin, commonly translated as an engine preheater or block heater, is a device used to warm an internal combustion engine before it is started. This is particularly useful in cold climates where low temperatures can make starting a vehicle difficult and increase engine wear. The preheater typically works by circulating a warming fluid, usually coolant, through the engine block. This fluid is heated by an electrical heating element.

There are several types of esilämmittin systems. The most common are immersion heaters, which are placed directly into the engine's coolant system, and circulation heaters, which use a small pump to move heated coolant. Some systems also use a heating element that directly heats the engine oil. The heating element is usually powered by an external electrical source, such as a standard household outlet, through a cord that runs from the vehicle.

The benefits of using an esilämmittin include easier engine starting in cold weather, reduced wear on engine components during cold starts, improved fuel efficiency as the engine reaches optimal operating temperature faster, and a quicker supply of heat to the vehicle's cabin. The installation of an esilämmittin usually involves tapping into the engine's cooling system or oil system and requires a connection to an electrical power source.
