CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE

摘要

Prevention heating control is performed with an objective of evaporating light oil and the like adhering to an inner circumferential wall of a glow hole. In the prevention heating control, a temperature of a heater is controlled so that a temperature in the glow hole becomes 180 °C to 380 °C. Decomposition heating control is performed with an objective of decomposing a binder component of the deposit accumulating on the surface and the inner circumferential wall. In the decomposition heating control, the temperature of the heater is controlled so that the temperature in the glow hole becomes 400 °C to 500 °C. The prevention heating control and the decomposition heating control are selectively performed after an end of start time control. In the start time control, a temperature around the heater is controlled to 700 °C to 900 °C.
