Abstract
A multipurpose engine controller comprises a control unit for switching between supplying and stopping power supplied from an ignition circuit to a spark plug on the basis of two states, i.e., the operating state of the multipurpose engine determined based on a detection signal from the engine speed sensor, and the state of the level of the oil inside the crankcase determined based on a detection signal from the float-type oil level sensor.
Claims4
A multipurpose engine controller for controlling a multipurpose engine, the controller comprising:
- a power generator for generating power via a motive power of the multipurpose engine;
- an ignition circuit for firing a spark plug using the power generated by the power generator;
- an engine speed sensor for detecting a speed of the multipurpose engine;
- a float-type oil level sensor for emitting an oil level drop detection signal when the level of the oil pooled in the crankcase of the multipurpose engine has dropped to a fixed lower-limit level;
- and
- a control unit for controlling the ignition circuit,
- wherein the control unit determines an operating state of the multipurpose engine on the basis of a detection signal from the engine speed sensor, determines the state of the level of the oil on the basis of a detection signal from the float-type oil level sensor, and controls the ignition circuit so as to supply and stop power to the spark plug on the basis of the operating state of the multipurpose engine and the state of the level of the oil.
