Abstract
When starting an engine, the engine is driven by a starting motor and, at the same time, a fuel heating heater can be operated. If the engine is stopped and then immediately restarted, the operation of fuel heating heater is controlled according to the operation time of the fuel heating heater in the last operation. That is, if a period of time is brief between a stopping and a restarting of the engine, heat generated when the fuel heating heater was operated last remains and, in consideration of the amount of that residual heat, generation of heat by the fuel heating heater is restricted.
