Abstract(J) | 乗用車の認証時の排出ガス試験は、温度湿度が一定に保たれた環境で実施される。しかし実際の走行環境では、梅雨時の高温高湿、冬場の低温低湿など様々な条件が考えられる。そこで、温度湿度を変化させて乗用車の排出ガス試験を実施した。得られた結果について、温度湿度の影響を車両側および分析計側の両面から検討した。 Translation |
Abstract(E) | The ambient conditions in the emission measurement test procedure for light duty vehicles are defined as an almost constant temperature (23degC) 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. In this study, several couple of surrounding 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. |
