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
