Claims

[Scope of utility model registration claim] The dwell angle and ignition timing are determined based on the crank angle signal, engine speed signal, engine load signal, environmental signals such as water temperature, etc. Switch,
In an idle speed control system that determines the idle air amount based on an idle disturbance signal from a power steering switch, etc., when the test terminal is turned on during initial adjustment of the electronic advance angle, an idle disturbance signal is output to determine the idle air amount. 1. An engine control device for initial adjustment of an electronic advance angle, characterized in that the control unit outputs an initial adjustment signal for increasing the idle rotation speed by prospectively increasing the idle rotation speed.
