Ignition timing control for marine engine |
摘要 |
The present invention is an ignition control system controlling ignition firing timing of an ignition element associated with an engine having an output shaft powering a water propulsion device, an intake system including a throttle valve, and a sensor providing an output signal corresponding to each revolution of the output shaft. The ignition control system calculates a base ignition firing timing from a time between successive previous output signals, determines if a condition of engine acceleration or deceleration exists from a rate of change in the throttle valve position and modifies the basic ignition firing timing based on a condition of engine acceleration or deceleration.
