A PREVIOUS PAPER (1*), reported on fuel consumption reductions achieved, by the use of a Regenerative Power Train system, applied to a city bus.An overall fuel economy gain of 20% was obtained previously, on the track, when operating the bus on the City Business District cycle (2) [CBD cycle, 20 mph maximum speed and 7 stops per mile], and a similar 30 mph cycle.The results reported here, were obtained using a CBD type driving cycle and indicate the extent of the reductions in regulated diesel exhaust emissions, achievable with a Regenerative Power Train.NOx was reduced 19 percent somewhat in line with the percentage improvement in fuel economy; particulate and CO emissions were more strongly influenced, with reductions of 27 and 60 per cent, respectively. HC emissions were the least affected with a reduction of 8 percent.
