Research and Test for Electronic Control Ignition System of Two-Stroke Gasoline Engine

Based on not doing many changes of the twostroke gasoline engine, an electronically controlled system has been developed which includes a semidirect injection system and an electronically controlled ignition system. With the hardware and software design, an ECU (electronic control unit) of twostroke engines has also been developed. After calibrating the injection timing, injection quantity and the advanced spark angle, the controlmap has been obtained. The experiments show that the engine performances are improved with this system.
