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. | |
