ABSTRACT:
A lubricating oil supply controller for a two-cycle engine is disclosed, wherein a lubricating oil is supplied to an intake air passage separately from fuel without mixing in advance the lubricating oil with fuel which is to be supplied to an engine. In this controller, a non-contacting type electrometer provided at a carburetor detects the fuel supply flow rate as a voltage. Thus detected voltage value is transmitted to a computer as a digital input through an analog-to-digital converter. This computer operates calculation by serving the input as a parameter and transmits a desired digital control signal to a step motor. The step motor is operated in response to the digital control signal and control a lubricating oil injection valve. In this way, the lubricating oil in its proper flow rate according to fuel supply flow rate is supplied to the engine.
