Abstract (en)
[origin: EP0594903A1] A capacitor (C2) stores energy obtained through rectification of the output of an AC generator (1) driven by an engine, and it is discharged periodically by a transistor (5) through a solenoid (4) of a solenoid pump. A pulse prior to smoothing is obtained from the output of the AC generator (1) through a diode to be used as an engine rotational rate signal for obtaining a transistor (5) turn-on timing. The lubricating oil pump is driven independently of the engine rotation, and it is possible to supply the minimum necessary lubricating oil reliably in a two-cycle engine without any battery as well. A common line is provided to a power source line and an engine rotational rate signal line, thus providing a lubricating oil pump drive circuit for a two-cycle engine, which requires a low assembling cost. <IMAGE>
