| Abstract(J) | RDE試験が乗用車に適用される．走行中のHEV等は，エンジン運転の停止頻度が高い．エンジン停止時おいても，車載型分析装置により排ガスが計測され続けるため，排気管内の排ガス濃度の低下を招き，正しく評価できない恐れがある．そこで，排ガス計測をエンジンの駆動に併せて間欠的に動作させる手法を検討し評価した． Translation |
| Abstract(E) | To estimate the on-road emissions of Light-duty vehicles, Real Driving Emission (RDE) testing method is adopted. Engine operated duration of HEV and PHEV is shorter than that of conventional engine vehicles. At RDE test, we use the Portable Measurement Emissions System (PEMS). Conventional PEMS is continuously sampling emission during the engine-stop. Therefore, it is difficult to measure the correct emissions of HEV and PHEV. In this study, to estimate more correct RDE data, we validated another approach, which operate PEMS by intermittent sampling. As the result, there is a possibility that we obtain the correct RDE data of HEV and PHEV by using this approach. |
