A diesel engine working on dual combustion cycle has a compression ratio 10 and cut off ratio 1.5. The pressure at the beginning of the compression is 2 bar and the maximum pressure in the cycle is 100 bar. 

Determine the thermal efficiency and the mean effective pressure of the cycle. Also calculate the actual mean effective pressure and the thermal efficiency of the cycle assuming the diagram efficiency to be 0.75 and the mechanical efficiency to be 0.82.
