To anaIyze and considerate on the exhaust emissions of medium speed marine diesel engine used heavy oil, the experiments are carried out at 6-measuring points on propeller curve with diesel oil and each different 4-heavy oil. Also, fuel injection timing is setted BTDC 17℃A, and intake air temperature is maintained uniformly at 45℃ to make the same operating condition. The results of this study can be summarized as follows, 1. Soot emission is generated in proportion to fuel density and residual carbon in fuel. 2. NOx emission is decreased in almost straight line in accordance with increasing of engine RPM and mean effective pressure. 3. CO₂ emission is generated in proportion to caron contents in fuel oil, that is, CO₂ emission of heavy oil is more than diesel oil because of much carbon contents. 4. SO₂ emission is generated wholly in proportion to sulfur contents in fuel oil.
