Double OHC lifter-type four-valve drive—a type of drive mode that uses four valves for a single cylinder, and double overhead camshaft and lifters to drive the valves, it effectively guarantees YF 300 engine’s big power and torque output, simplifies the valve actuating mechanism, reduces friction and lowers the running inertia, thus realizing the high-speed power following performance
With the help of CAD/CAE based computer aided analysis, and based on the engine’s features, a balancer vibration dampening system is designed and reasonably positioned, in the mean time a balancer driving gear with its own supplementary teeth is used, thus achieving a better engine vibration dampening effect
All-aluminum surface porcelainized nickel-plated cylinder—features good tightness, a low emission level, a long service life, high wear resistance and a light mass
Adoption of a tooth chain achieves a low noise level and a long service life
The engine structure is simplified as much as possible yet engine’s performance is still guaranteed, making the engine’s conformation very compact, and its weight much lighter than other engines of the same displacement
