Description:

The purpose of the intake valve is to suck air into the engine and mix it with fuel for combustion. The function of the Air-out valve is to discharge the burnt fuel and air mixture. This multi valve structure is easy to form a compact combustion chamber, and the fuel injector is arranged in the center, so that the fuel air mixture can burn faster and more evenly. The weight and opening of each valve shall be reduced appropriately to make the valve open or close faster. In order to improve the efficiency of intake and Air-out, multi valve technology is adopted now. It is common that each cylinder is arranged with four valves, and four cylinders have 16 valves in total.
