ER
External power supply engine preheater is an auxiliary engine starting aid which is used when the engine start-
ing is difficult due to cold weather in which the ambient temperature drops under -20 °C or even when it is higher
than -20 °C .
It utilizes the external power supply (single-phase AC current 200 to 240 V) to make the engine starting up eas-
ier by heating the engine coolant and oil in the engine oil pan.
