Abstract
A direct injection diesel engine is provided with a fuel injection nozzle which is capable of performing a multistage injection. In a middle-or-high load region, in order to decrease soot, an after-injection is performed immediately after a main injection. In a case of fuel with a low Cetane number, the after-injection can cause a worsening of soot. Hence, an ignition delay interval (period of time) of the main injection is determined. In a case where the ignition time delay interval (period of time) is equal to or above a threshold value, the after-injection is inhibited.
