A TURBO DIESEL CAR TO BEAT CLEAN AIR LOBBY

A turbo-charged, diesel-engined car now being developed by Mercedes-Benz, Stuttgart, is mainly intended for the American market and complies with EPA environmental requirements. The 3-litre, 5-cylinder engine develops 80 bhp as standard; but when equipped with the T3 Garrett AI research turbocharger, an output of 115 bhp is claimed. Tests have shown that when fitted to the Mercedes-Benz S class of cars, the engine is capable of giving a fuel consumption of 25-26 mpg over the specified EPA test. The diesel engine not only offers advantages of low emissions but also only requires one grade of fuel compared with the modifications required to suit petrol engines for different grades of fuel in various countries. Rotating at 130000 rpm, the turbocharger is kept turning at its maximum speed by a wastegate which mixes excess air with engine exhaust. /TRRL/
