This experimental study was conducted to identify power and emission characteristics using a dynamometer and an exhaust gas analyzers in the commercial engines mounted with the naturally aspirated diesel engine and the turbo-charged diesel engine.
The power capability difference between the two experimental models was insignificant at low speeds. But the power capability difference at high speeds significantly increased in the turbo-charged diesel engine, compared to the naturally aspirated diesel engine. As for exhaust gases, especially NOx was measured slightly higher in the turbo-charged diesel engine with an insignificant difference. Exhaust gases were reduced through EGR, resulting in CO2 emission suppressed.
Consequently, the turbo-charged diesel engine showed higher power than the naturally aspirated diesel engine and was found to be more efficient in terms of the exhaust gas considering power improvement.
