The result of testing on viscosity index, flash point, foam test, total acid, carbon residue rame, oxidation and water content indicates that 三陽金帝 2T, Esso 2T and GIBSON have better materialization performances. 2、Implement the total up to 200 times of the model of the vehicles’ movement, idle capacity and white smoke opacity that arrange 10 kinds of two-stroke motorcycle with 20 kinds of engine oil. In accordance with the result of tests, we can probe into the relation among white smoke, rotational speed of the engine, load, engine oil’s type and the supply of engine oil. In addition, we can analyze and realize the white smoke produce mechanism then find out that the average smoke degree on both half-synthetic engine oil and environmental protection engine oil are less than the mineral oil. Nonetheless, there is not a big difference in the average smoke degree between half-synthetic engine oil and environmental protection engine oil. 3、Collect the standards of CNS motorcycle engine oil in Japan and Taiwan.
