Study of the Ignition Advance Angle Adjustment System of 2-stroke Engines Fueled with Alcohol and Gasoline

By analyzing the influence of ignition advance angle on engine performance,a conclusion is drawn that the ignition system of 2-stroke engines fueled with alcohol and gasoline should be improved.The computer controlled ignition technology used in the ignition system of current automobile industry is improved and transplanted to 2-stroke engines.An ignition control unit ECU is added to the original ignition system to change it into an electronic control system.The improved ignition system can calibrate the ignition advance angle and realize real-time adjustment of the ignition advance angle according to the different rotation speed and working conditions of engines to find out the perfect ignition advance angle.The improved 2-stroke gasoline engine can further improve the power,economy and emission performance of engines.
