Ignition control for motorcycle engine - adjusts ignition timing to limit engine load in bottom velocity range

摘要

The ingition control engine has a detector (2) providing a signal when the motorcycle is operated in the bottom velocity range, to adjust the ignition angle so that the engine output load is limited. Pref. the ingnition timing control (3) uses the detected engine revs and the detector signal to calculate the engine ignition setting subtracted from a reference angle to provide the ignition angle compared with the detected rotation of the engine crankshaft. ADVANTAGE - Improved handling of motorcycle.
