A supercharged diesel engine comprising:
- an intake pipe;
- a diesel engine including an air cleaner and a cylinder which are installed at both ends of said intake pipe, respectively;
- a supercharge provided in said intake pipe and set to be driven by said diesel engine via clutch means;
- a bypass passage which is installed in said intake pipe in parallel with said supercharger;
- a bypass valve and restriction means which are arranged on said bypass passage in series;
- and
- said restriction means restricting said bypass passage sufficiently such that said supercharger receives sufficient air that said supercharger is rotated by the air in the case that said clutch means is disengaged and said bypass valve is opened, thereby reducing friction wear of the clutch means.
