An Engine Heater is an electric heater that heats the engine of a car to give quicker starts in cold weather. They are connected to normal AC power overnight or before driving, via regular power outlets that are fed through a vehicle’s grille. This allows easier starting in cold temperatures, by keeping the coolant warm. Heaters are also available for motor oil so as to warm the oil and give the engine lubrication from the beginning of start-up. The rapid heat circulation caused by block heaters also aids the initial vaporization of fuel in the engine; because of this effect, block heaters reduce pollution, as poor fuel vaporization causes much higher emissions.
