The gas turbine uses a catalytic combustor to reduce emissions to substantially less than ULEV standards. The turbine has no gear box no lubrication system and no engine- driven accessories. The manufacturing cost is relatively low. The result is an affordable, compact, light weight power package with low emissions that can extend the range of electric vehicles to equal or exceed those of conventional cars, trucks and buses. INTRODUCTION A gas turbine-driven generator set is being developed for hybrid electric vehicles. It is flat rated at 24 kW, continuous, at temperatures up to 35ºC (95°F), sea level. A maximum of 30 KW is available for short term peak power. The primary fuel is unleaded gasoline although various other fuels can be used. The efficiency is 30% based on electrical output and fuel consumed. The electrical output is measured at the generator terminals. The generator set weights 36 kg (80 lb) with dimensions of 66 cm x 39 cm x 30 cm (26 in x 15.5 in x 12 in), not including electronics. It can be mounted vertically or horizontally. There is no oil required as the rotor runs on air bearing. The maximum emission levels are 0.0061 g/mi for NOx, 0.0044 g/mi for CO and 0.033 g/mi for HCS based on 130 Wh/mi. This is significantly les
