Evaluate the indicated thermal efficiency, Mechanical Engineering

Assignment Help:

(a) Briefly explain the various efficiency terms associated with an engine.

(b) A four cylinder engine running at 1200 rpm delivers 20 KW. The average torque when one cylinder was cut is 11oNM. Evaluate the indicated thermal efficiency if the calorific value of the fuel is 43 MJ/Kg and the engine uses 360 gram of gasoline per Kwh.
