This is a thesis about the experiment of comparison characteristic of exhaust gas in the same condition between diesel engine that is equipped turbocharger to increase effectiveness of the engine which is recently used in a lot of industry which requires high power. Resulting of the experiment turbocharger diesel engine according to response power, difference in low speed is not significant, but in high speed, effectiveness of turbocharger diesel engine is almost the same in four turbocharger. In other hand, in exhaust gas experiment, high response power turbocharger model exhausts less NOX, but it doesn’t significantly affect the result when it comes with decreasing of CO2 and effectiveness of similar power characteristic. As a result, the high response power turbocharger diesel engine is economically effective comparing with the low response power turbocharger diesel engine.
