INTERNAL COMBUSTION ENGINE |
摘要 |
An internal combustion engine includes a control unit determining the occurrence or non-occurrence of dew condensation in a tip portion of a nozzle based on a nozzle heat receiving amount of an injector and a nozzle tip temperature of the injector at a point in time when ignition is turned OFF and performing nozzle corrosion prevention control when the dew condensation is determined to occur in the nozzle tip portion. The control unit calculates a nozzle tip temperature reduction rate based on the nozzle heat receiving amount, calculates a dew point arrival time based on the reduction rate, and determines the occurrence or non-occurrence of the dew condensation in the nozzle tip portion based on the dew point arrival time. |
