ABSTRACT:
A lubricating oil supplying system for a two cycle engine that includes a reciprocating engine drive lubricant pump and a solenoid controlled bypass valve for selectively delivering lubricant to the engine of by bypassing it back to the inlet side of the lubricant pump to control the amount of lubricant supplied to the engine. The duty cycle of solenoid is increased as the engine speed is decreased and the duty cycle is also decreased when the throttle is opened rapidly so as to insure the proper amount of lubricant flow to the engine under all conditions, both transient and steady state.
