ABSTRACT:
The subject system is primarily for supercharging a low compression Diesel engine. It includes connected turbine and compressor elements and a hydraulic system having a first motor/pump unit mechanically connected with the turbine and compressor elements and a second motor/pump unit mechanically connected, through an output transmission, to the engine. The hydraulic system also includes a plurality of valves, an accumulator, a reservoir, and ducts connecting such elements and the motor/pump units. The first motor/pump unit is of the variable volume type and is controlled by an actuator responsive to fluid pressures in the inlet and exhaust manifolds of the engine. The second motor/pump unit is a fixed displacement device which may be driven by fluid pressure from the accumulator in the engine starting phase and by the engine to supply hydraulic pressure to recharge the accumulator and assist in controlling the operation of the supercharger. The operation of the supercharger is also controlled in part by a valve mechanism responsive to fluid pressures generated by the motor/pump units during predetermined phases of engine operation.
