ABSTRACT:
An auxiliary power system for a motor vehicle primary engine used to drive primary engine accessories when the primary engine is not operating. The system comprises a secondary engine that drives a hydraulic pump. The hydraulic pump is connected to a hydraulic motor. The hydraulic motor is integrated with an accessory belt drive system on a primary engine. The secondary engine drives the ABDS system through the hydraulic pump and hydraulic motor when the primary engine is not operating, thus allowing various primary engine accessories such as air conditioning to be operated while the primary engine is off. A one-way clutch on the primary engine crankshaft prevents the primary engine crankshaft from being turned when the hydraulic motor is driving the belt. A one-way clutch on the hydraulic motor prevents it from being driven when the primary engine is in operation.
