Abstract(J) | 路上走行試験では,梅雨時の高温高湿,冬場の低温低湿など様々な条件下での実施が考えられ,それらの排出ガス性能への影響を考慮しなければならない.そこで,温度湿度を幅広く設定可能なシャシダイナモ設備にて車載式分析計を用いて台上試験を実施し,得られた結果について温度湿度の影響について検討した. Translation |
Abstract(E) | The ambient conditions in the emission measurement test procedure for light duty vehicles are defined as an almost constant temperature (23 deg C) and humidity (50 %RH). However, in the real driving situation, the temperature and humidity are widely dispersed, for example, high temperature and high humidity during the rainy season, and low temperature and low humidity during the winter season. Even during a real driving emission (RDE) test, the temperature and humidity are fluctuated. In this study, several couples of ambient conditions have been adopted for the emission measurements and the results are discussed from the effects on the vehicle and on the emission measurement system. |
