Effect of Test Cycle & Modes on Motorcycle Exhaust Emission
The effect of test cycle and modes of motorcycle emission test on exhaust emission characteristics is studied. By analyzing the online testing emission data of CO. HC & NOx according to Chinese emission standard at phase Ⅲ for EFI motorcycle FY125-3P. the relationship among emission content, test cycle and modes was studied. It is concluded that the emission content at the first test cycle has a great contribution to the overall emission. And for the first test cycle, the test mode related with the emission peak of CO is deceleration mainly, that of NOx is regularity and high load. and that of HC is deceleration and middling load condition. It is found that if there is a flameout during the test cycle, the CO emission will increase much.
