ENGINE CONTROL APPARATUS
First Claim
1. An engine control apparatus which comprises a governor control mechanism for keeping an engine frequency constant, decides the “
- presence”
or “
absence”
of an engine load by a throttle aperture, and forcibly changes the engine frequency to a predetermined frequency depending on the presence or absence of the load, comprising;
an engine controlling unit (10) for controlling fuel supply to an engine (1);
an engine temperature detecting unit (4) for detecting an engine temperature of said engine; and
a threshold changing unit (10a) for changing each throttle aperture as a threshold for deciding the “
presence”
or “
absence”
of an engine load depending on the engine temperature detected by said engine temperature detecting unit (4).
