چکیده:

In this paper a study to analyze the influence of engine parameters on second law turbocharger efficiency is investigated. The analysis has been performed by means of a four stroke, four cylinders turbocharged diesel engine and tests have been carried out in constant speed with different loads. In this work exhaust species were measured and exergy flow of exhaust and turbine power output has been calculated. Then turbocharger second law efficiency calculated. The results show that higher bmep, higher exhaust pressure and temperature, higher equivalence ratio and higher engine speed increase turbocharger second law efficiency. Higher second law efficiency of turbocharger means higher turbine work
with a specific amount of exergy flow of exhaust. That means turbocharger feed back in transient conditions could be improved by higher engine speed, higher inlet turbine temperature and higher fuel-air ratio due to better available work transfer between engine cylinder and turbocharger.
