Abstract
The variable intake and exhaust control valve system for the in-line four-cylinder motorcycle engine was developed for realization of high engine power in all the engine speed ranges. Both the variable intake and exhaust control valves are operated by one servomotor. For high engine speeds, the exhaust collector pipe design for merging of each exhaust gas flow at 180 degrees phase difference is used. For mid engine speeds, the design for merging of each exhaust gas flow at 360 degrees phase difference is used. Two modes are provided to the intake control, and three modes are provided to the exhaust control. Along with exhaust-gas treatment systems such as the catalyst and air-injection system, high engine performance with optimum driveability and reduced emission are realized.
