ABSTRACT:
The present invention pertains to a vehicle having an internal combustion engine. The internal combustion engine has a first plurality of movable parts which require lubrication during relative movement to reduce wear. The vehicle has N systems, each of which has a corresponding plurality of movable parts which require lubrication during relative movement of reduce wear. There is also an electrical mechanical starter mechanism for initiating movement within the engine. In addition there is a first oil supply system having a main engine oil pump which circulates oil to the first plurality of moveable parts and responds to movement within the engine. Also a supplemental engine oil pump communicates with the first oil supply system. The vehicle also has N oil supply systems. Each of the N oil supply systems have a corresponding main oil pump which circulates oil to the corresponding plurality of moveable parts in response to movement within the corresponding system. The improvement of the invention includes a device for activating the starter mechanism in the first mode of operation in which movement is not initiated within the engine and the N systems, and in a second mode of operation in which movement is initiated within said engine to effect combustion and in the N system to effect operation thereof. The improvement also includes N supplemental oil pumps.
