Study on Control Strategy of Ignition Advanced Angle of Electronic Control Motorcycle Engine 2008-01-1536

A study was made on the ignition advanced angle of motorcycle engine with electronic control technology. This paper presents an electronic control ignition system, describes the measuring method of key parameters including engine velocity, load and the reference ignition signal of engine. On the basis of operating characteristics, the engine operating mode are divided into four parts: start, idle, partial load, full load. The electronic control ignition control system adopts the proper ignition control strategy in accordance with the operating mode.
The electronic control ignition system was applied to the motorcycle engine FY156FMI. The experimental verification indicated the control strategy of ignition advanced angle can attain the excepted function. It was conducted engine test and vehicle emission chassis test. The test results showed that the performance of power, fuel consumption and exhaust emission of electronic control engine developed were better than that of original engine equipped with CDI ignition system, and the exhaust pollutant emissions of motorcycle with electronic control engine developed can meet the requirements of Chinese Phase III motorcycle emission standard.
