Abstract
The utility model relates to a digital speed limit igniter for motorcycles. The utility model uses a micro computer controller and an interface circuit to replace the existing ignition control device on the basis of the existing igniter for common motorcycles. A vehicle speed detection sensor is added and the pulse signals generated from the vehicle speed detection sensor are taken as vehicle speed control pulse signals which are transmitted to the input end of the micro computer controller. The micro computer controller calculates the pulse period of the vehicle speed control signals and compares the pulse period with the preset clock period. When the pulse period of the vehicle speed control signals is less than the preset value, the micro computer controller controls the discharging time of a spark plug for proper hysteresis by an interface circuit in order to cause the ignition angle to mismatch the rotating speed of an engine for lowering down the power of the engine to limit the speed of the motorcycle. Compared with the existing speed limit technique, the utility model has the characteristics of artful design, novel structure, low cost and accurate speed limit range and does not increase the volume of the motorcycle.
