    摘要: A transmission ( 2 ) connected to the rear end of a transversely-mounted, four-cylinder diesel engine ( 1 ) includes a front-wheel differential gear box ( 12 ) extending toward the rear of the vehicle. A supply pump ( 14 ) is mounted on the vehicle front side of the front end part of the engine ( 1 ). High-pressure fuel from the supply pump ( 14 ) is fed to fuel injection valves ( 13 ) via a common rail. The supply pump ( 14 ) includes a single plunger ( 30 ) that is reciprocally moved by a cam ( 32 ) driven by a crankshaft of the engine. The plunger ( 30 ) is reciprocally moved to produce inertial forces opposite in phase to second-order inertial forces of the pistons and associated parts of the engine ( 1 ), which effectively reduces pitching vibrations due to reciprocal second-order inertial forces of the pistons and associated parts of the engine and in turn reduces booming noise.
