Ftp75 drive cycle
WebLow vehicle occupancy rates combined with record conventional vehicle sales justify the requirement to optimize vehicle type based on passengers and a powertrain with zero-emissions. This study compares the performance of different vehicle types based on the number of passengers/payloads, powertrain configuration (battery and fuel cell electric … Webdrive-cycle emissions results from engine-dynamometer studies. Table 1 shows the engine operating conditions that were developed by the Ad-Hoc working group and that were used for this study. The weighting factors were developed by the Ad-hoc group and are indicative of the amount of time spent at similar conditions during the FTP driving cycle.
