1、According to the brand, the price and the standard, we collect 20 different kinds of two-stroke motorcycle engine oil in the marketplace. 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. Furthermore, we not only investigate but also analyze the hobbies of where the two-stroke motorcycles’ owners change their engine oil and how much they spend on it.
4、After considering the measuring ability in every domestic manufacturing and laboratory at present, we recommend that the motorcycle manufacturing and the companies of engine oil could not only blend but also ameliorate two different kinds of two-stroke engine oil into one in one single brand to sell a better quality of two-stroke engine oil for a special purpose in the marketplace.
