The air intake of a diesel engine used as a main power device is connected to a supercharger air outlet, wherein the supercharger is driven by an spark ignition engine. Discharged air from the supercharger is directed to an inlet system of said diesel engine for said main device by a pipe. Exhaust gas from the spark ignition engine is supplied between an inlet system of the supercharger and an inlet system of the diesel engine via an exhaust regulating valve. The regulating valve is regulated according to the operating condition of said diesel engine. Without deterioration in diesel engine startability and output, the engine system provides overall exhaust treatment which decreases especially NOx. |
