There are provided with a plurality of injection nozzles one ends of which are respectively inserted into a cylinder head every cylinder and other ends of which are covered with a cylinder head cover. A single common rail provided in parallel with a crankshaft is connected to a fuel injection pump through a first fuel pipe and connected to each injection nozzle through a plurality of second fuel pipes. The common rail is housed in the cylinder head cover, the front end of a first short pipe protruded from the common rail faces a first insertion portion formed in the sidewall of the cylinder head, and the first fuel pipe is connected to the first short pipe through the first insertion portion. Thereby, it is possible to decrease a fuel supply system using the common rail in weight and cost and improve the outside quality.
