| Abstract(J) | 重量車における水素消費は，絶対量が多いことやマップ状の多数の測定点をとるケースが想定されることからボンベ重量による測定が現実的でない．そこでコリオリ式流量計を用いてボンベガス試験と車両試験を行い，重量法との比較を行った．両者は高い相関を示す一方で，走行サイクルによってはややばらつきがみられた． Translation |
| Abstract(E) | The measurement of consumed hydrogen weight in the off-board gas cylinder is a common approach to measure the hydrogen consumptions of light duty vehicles. Concerning hydrogen consumption measurement of heavy-duty vehicles, this approach is not realistic because the amount of hydrogen consumption is larger than that of a light duty vehicle. Therefore, an approach which directly measures the amount of mass flow of hydrogen from the cylinder to the powertrain system is studied. In this paper, the accuracy of measured results of the mass flow of hydrogen and the challenges to improve the accuracy will be discussed. |
