    • A lubricating system and method of operating the system for an internal combustion engine wherein the amount of lubricant supplied to the engine from a positive displacement engine driven pump is varied by selectively delivering lubricant from the pump to the engine or bypassing the lubricant back to the return of the pump. The amount of lubricant supplied is varied by changing both the duty ratio of the lubricant supply and the duration of engine supply in response to a map of engine conditions. Various control routines are disclosed and in each the lubricant supplied to the engine is monitored so that once a finite amount of lubricant is supplied, lubricant is not supplied again to the engine until that amount previously supplied has been consumed.
    • 一种操作内燃机系统的润滑系统和方法,其中从容积式发动机驱动泵供给发动机的润滑剂的量通过选择性地将润滑剂从泵输送到发动机或绕过润滑剂返回到返回 的泵。 通过根据发动机状况的图来改变润滑剂供给的占空比和发动机供给的持续时间来改变润滑剂的供给量。 公开了各种控制程序,并且在每种情况下监测供应给发动机的润滑剂,使得一旦提供有限量的润滑剂,润滑剂就不会再次提供给发动机,直到先前提供的量消耗。
