APPLICATION OF CNG FUEL ON MOTORCYCLE ENGINES

With the strong development of motorcycles in Vietnam, it has directly affected the living environment and human health. The article analyzed and applied CNG gas fuel on Honda wave motorcycle engines with a carburetor fuel supply system. This contributes to reducing harmful emissions and reducing oil depletion pressure. The research team calculated and analyzed to come up with a solution to use two CNG fuel injectors in accordance with the design of the engine. Research results can confirm that the engine when using CNG runs stably and reliably. Engines operating CNG have reduced power and torque by 8% and 6%, respectively, compared to gasoline. However, converting gasoline engines to CNG fuel is easy, saving design and manufacturing costs, and can be applied and installed on vehicles already on the market. The installation requires no intervention in the engine combustion chamber and is simple.
