Claims (1)

[Scope of utility model registration request] a crank angle sensor that detects a reference angle of a crankshaft of an engine; an ignition timing setting means that sets an ignition timing according to the operating state of the engine as a delay angle or delay time from the reference angle; The actual delay angle or delay time corresponding to the delay angle or delay time set by the ignition timing setting means is measured using the output signal as a starting point, and the ignition is started when the delay angle or delay time from the reference angle has elapsed. An electronic advance device having an ignition signal generating means for generating a signal includes a test terminal that is set at the time of initial adjustment of the relative phase of the crank angle sensor with respect to the crankshaft, and the test terminal is set in the ON state. What is claimed is: 1. An engine control device for initial adjustment of an electronic advance angle, characterized in that the engine control device is provided with an intake air increasing means for increasing the amount of intake air of an engine by detecting the amount of intake air.
