To improve efficiency of diesel engine which requests high output recently and is used all kinds of industrial areas, this thesis experimented dynamic characteristics and exhaust gas characteristics of diesel engine installed by supercharger of correspondent output 200HP and natural inhalation diesel engine through the dynamometer and exhaust gas analyzer in same condition. As the result of experiment with natural inhalation diesel engine and diesel engine installed by supercharger, there were a few differences of output, but dynamic characteristics at high speed showed increased output and efficiency of the engine installed by supercharger. On the contrary, in exhaust gas characteristics, the model installed by supercharger showed increased exhaust gas such as $NO_X$, $O_2$, etc, but added value of exhaust gas is low if considering $CO_2$ reduction and efficiency of dynamic characteristic's increase. Based on the results, diesel engine installed by supercharger is expected to show higher economic feasibility than natural inhalation diesel than natural inhalation engine from an angle of efficiency. Keywords: 200hp class Turbocharger, Exhaust Gas, Engine Performance, Marine Diesel Engine.
