概要

In order to measure gasoline vehicle emissions at load tests, we have evaluated technically a prototype on-board emissions analyzer. As a result, it was confirmed that gas analysis performance of the prototype device was sufficiently useful ; however, measurement accuracy of gas flow rate required mass conversion was insufficient. Then, we have contrived a new measurement method of gas flow rate that is based on speed-density method. From various load tests, it was found that the test system using both the on-board emissions analyzer and the new flow measurement method were effective for an analysis of emissions characteristics of running vehicles in real-world.
