Abstract
The authors developed a simple simulation method of motorcycle emission mode, using a popular chart calculation software for a personal computer, to calculate from the motorcycle's various specifications and the engine bench test data. The precision or verification by a mass production model was of a sufficiently good level. This simple simulation method was easy to use and effective in reducing the research period.
Moreover, the experimental motorcycle (Scooter, Two-stroke, 50cm3) that adopted the stratified combustion system for a fuel economy improvement and CO2 reduction, was made and experimented on the ECE40 mode as a sample case.
Approximately 20 % of fuel economy improvement and CO2 reduction were achieved and the estimation was effectively proved.
