Question: an ideal diesel engine has a compression ratio of 194...

Question details

An ideal diesel engine has a compression ratio of 19.4 and uses air as the working fluid. The state of air at the beginning of the compression process is108 kPa and 20°C. If the maximum temperature in the cycle is not to exceed 2,360 K, determine (a) the thermal efficiency 11 th and (b) the mean effective pressure. МЕР % Round the final answer to one decimal place. kPa Round the final answer to one decimal place. Assume constant specific heats for air at room temperature.
