PROBLEM TO BE SOLVED: To provide a common rail diesel engine enabling the easy removal of a head cover 2. SOLUTION: In this common rail diesel engine, to connect a fuel feed pipe 9 to the fuel inlet 5 of a fuel injection nozzle 4 and a fuel return pipe 10 to the fuel return outlet 6 of the fuel injection nozzle 4, the fuel inlet 5 and the fuel return outlet 6 of the fuel injection nozzle 4 are disposed in the head cover 2 so that, when the nozzle connection part 9a of the fuel feed pipe 9 is extracted from the connection part through hole 11 of the head cover 2 to the outside of the head cover 2 by disconnecting it from the fuel injection nozzle 4, the head cover 3 can be removed from a cylinder head 1 without disconnecting the fuel injection nozzle 4 and the fuel return pipe 10. The head cover 2 can be attached to and detached from the cylinder head 1 without removing a glow plug from the cylinder head 1. COPYRIGHT: (C)2008,JPO&INPIT
