Abstract
A diesel engine comprises an EGR valve, an intake throttle valve, a control unit for controlling those EGR valve and intake throttle valve, and a detection unit for detecting the intake air quantity upstream of an EGR gas inlet portion, the diesel engine implementing a premix combustion at least in the prescribed operation region. The control unit, at least in the operation region in which the premix combustion is implemented, determines a target intake air quantity necessary for igniting the gas mixture at the target timing based on the engine operation state and controls the intake throttle valve and/or EGR valve so that the actual intake air quantity detected by the detection unit matches the target intake air quantity. As a result, the ignition timing of the fuel in premix combustion can be easily and optimally controlled.
