The Australian company developing a new compact internal combustion engine, CMC Power Systems Limited, said its new 500cc prototype engine had successfully fired up for the first time at Cosworth Technology's Northampton engine building plant in the UK. It has been specifically designed to be the 'prime mover' for CMC's Automotive Auxiliary Power Unit (AAPU), an electricity generator which is expected to find a rapid route to market as an on-board source of electrical power for emergency vehicles, trade vehicles, camper vans and mobile homes.
