Problems in DIESEL cycle

          A diesel engine has a compression ratio of 15 and heat addition at constant            pressure takes place at 6% of stroke. Find the air standard efficiency of the engine. 
Take γ for air as 1.4.

Given:

                  r = 15,  heat addition takes place 6% of stroke

    Result:

           Air standard efficiency = 61.2 %
