A diesel engine takes in air at 0.95 bar and 21 o C and operates on the dual combustion cycle. Calculate the air standard thermal efficiency if the compression ratio is 19/1 and the maximum cycle pressure is 68 bar. Assume that 40% of the total heat supplied is added at constant volume and the remaining 60% at constant pressure.

Question
A diesel engine takes in air at 0.95 bar and 21 o C and operates on the dual combustion
cycle. Calculate the air standard thermal efficiency if the compression ratio is 19/1 and
the maximum cycle pressure is 68 bar. Assume that 40% of the total heat supplied is
added at constant volume and the remaining 60% at constant pressure.
Transcribed Image Text:1. A diesel engine takes in air at 0.95 bar and 21°C and operates on the dual combustion
cycle. Calculate the air standard thermal efficiency if the compression ratio is 19/1 and
the maximum cycle pressure is 68 bar. Assume that 40% of the total heat supplied is
added at constant volume and the remaining 60% at constant pressure.
