Patent ID: 6935307

Claim:
A diesel engine comprising: a supercharger for pressurizing outside air and supplying the pressurized air as charge air into combustion chambers; a first heat exchanger, provided in a charge air channel extending from an outlet of the supercharger on a compressor side of the supercharger, for receiving a first medium and for exchanging heat with the charge air from the outlet of the supercharger; a second heat exchanger, provided in the charge air channel, for receiving a second medium having a higher temperature than the first medium and for exchanging heat with the charge air from an outlet of the first heat exchanger; and fuel injection timing control means for controlling a fuel injection timing of a fuel; wherein the fuel injection timing control means advances the fuel injection timing for a predetermined period of time when an engine load on the diesel engine is shifted to a low load from a high load and decreases to a predetermined level.
