Ignition apparatus
This patent describes an ignition apparatus for an engine having a crankshaft, comprising: first ignition signal output means for outputting a first ignition timing signal having a predetermined spark advance synchronously with the rotation of the engine; second ignition signal output means for outputting, as a signal for trolling, a second ignition timing signal which is delayed from the first ignition timing signal from the first ignition signal output means by a time interval representing the time required for the crankshaft to rotate through a predetermined angle; a spark advance operating circuit for performing an arithmetic operation on the basis of the output of the first ignition signal output means and for outputting a third ignition timing signal which respectively advances and delays in ignition timing in response to an increase and decrease in the rotational speed of the engine.
