The compression ignition engine

Assumed to be operating on ideal air-standard Diesel cycle has a compression ratio of 18 and a cut-off ratio of 2. At the beginning of the compression process, air is at 95kPa and 92 ⁰C . Accounting for the variation of specific heats with temperature,

i) determine the temperature after the heat-addition process

ii) thermal efficiency.

iii) using the available information determine the relative efficiency.
