A four-cylinder compression-ignition engine with a compression ratio of 18 has pistons with a bore of 9 cm and a stroke of 10 cm. The air pressure at the beginning of compression is 98 kPaa, and the temperature is 37 °C. The engine may be modeled by the air-standard Diesel cycle. The maximum cycle temperature is 1700 °K. If the engine produces 75 kW of power, determine: a) the heat supplied per cylinder b) the thermal efficiency c) the rpm required.
