At present, high-powered Diesel engines with exhaust-gas turbocharger and intercooler are used to an ever increasing extent for heavy vehicle applications. Since such vehicles are employed all over the world, the power units should operate reliably even under extremely high ambient temperatures. On the proving benches of Daimler-Benz, tests were made on a 90 V Diesel engine with exhaust-gas turbocharger and intercooler to determine the engine operational characteristics at air-intake temperatures between 20 deg C (68 deg F) and 30 deg C (122 deg F) and with variation of the temperatures in the coolant and fuel circuits (coolant from 80 deg C (176 deg F) to 120 deg C (248 deg F),and fuel from 20 deg C (68 deg F) to 70 deg C (158 deg F). Certain settings of the three temperature ranges: air, coolant, fuel, result in variations in the output and heat balance characteristics of the engine. The engineer, therefore, should be fully aware of these factors so that he can design the vehicle cooling system such as to avoid thermal overload of the engine and thus to ensure safety and reliability even at extremely high ambient temperatures.
