Q1) (15 points) A 2.5 lit, 4-stroke, compression ignition engine running at 3000 RPM operates on ideal Dual cycle. The engine is supplied with air at

and

. If the compression ratio is 14 , the cut-off ratio is

, and maximum temperature is 1527 . C, then determine: (Use table A.17, or take average

and

)) the net output work of the cycle, in

draw the

or

diagram. the total heat added, exergy destructed in the constant volume heat addition process the thermal efficiency of the cycle, the second law efficiency.
