Abstract
A V-type diesel engine with a common rail, which does not elongate a total length of the engine even if a supply pump and/or common rail becomes longer. Two intake manifolds are mounted on inner walls of two banks of the engine. The common rail spans these intake manifolds to leave space below itself. The fuel pump is located at a bottom of an interbank valley of the banks and the common rail extends above the fuel pump so that the fuel pump and common rail can extend in an overlapping manner. The space below the common rail can accommodate other devices such as turbocharger and EGR cooler. Thus, a compact engine can be designed. The common rail bridging the intake manifolds also serves as a reinforcing member against vibration of the two banks.
