An ideal diesel engine has a compression ratio of 20 and usesair as the working fluid. The state of air at the beginning of thecompressor process is 100 kpa and 27 C. The maximum temperature inthe cycle is 2200 K and the cutoff ratio is 1.2
Determine the following:
The internal energies at the beginning and the end of thecompression
The enthalpy before and end of the combustion
The internal energy before and end of the expansion
The heat input, heat rejection and network output
The thermal efficiency
