摘要： A control device for diesel engine controls a diesel engine with a turbo charger that coaxially joins an intake compressor and an exhaust turbine, and drives the intake compressor with energy of exhaust gas which flows into the exhaust turbine to pressurize intake air, and a fresh air/secondary air supply device that supplies fresh air or secondary air to an exhaust passage upstream of the exhaust turbine. The control device for diesel engine includes a gas flow stagnation region determination means that determines whether engine operation conditions or a state of the turbo charger are/is in a gas flow stagnation region, and a fresh air/secondary air supply means that supplies fresh air or secondary air to the exhaust passage upstream of the exhaust turbine by the fresh air/secondary air supply device when the engine operation conditions or the state of the turbo charger are/is in a gas flow stagnation region.
