Optimization of kirloskar petrol engine performance by using open engine control unit

This paper deals with developing test bench which will give us idea about how to tune engine parameters and also give the flexibility to change the parameters electronically. To achieve this old carbutretor system is relpaced by gasoline port injection system. To carry out experimentation modified kirloskar single cylinder water cooled engine is selected. In optimization process of kirloskar engine air-fuel ratio is try to maintain constant through out the operating range of engine. Initially in Experimentation work tuning of engine is done as per the same load and rpm condition as that of carburetor. The rpm range varies in between 1000 to 1800 rpm. And Throttle opening varies in range of 20 to 100%. The graphs of brake power and brake thermal efficiency vs rpm is plotted for each throttle opening and part throttle efficiency of ecu based system is compared with crburetor system. For tuning of engine we have taken generic ecu of performnce electronics company from US.
