Electronic lubricant metering system

摘要

Disclosed herein is an electronic lubricant metering system for an engine which includes a throttle for regulating the amount of fuel delivered to the engine, the system comprising a frequency to voltage converter for producing a first electrical signal representative of engine RPM, a potentiometer including a wiper coupled to move in response to movement of the engine throttle, the voltage appearing on the wiper producing a second electrical signal representative of the amount of fuel being delivered to the engine, an oil pump for supplying a variable amount of lubricant into the fuel delivered to the engine, and an electrical control circuit responsive to the first and second electrical signals for providing a control output which renders the oil pump operative to vary the lubricant/fuel ratio of the lubricant and fuel mixture delivered to the engine.
