Air or air and fuel mixture flow control in valve controlled internal combustion engines

摘要

In order to provide a controlled turbulence or angular momentum of air, air and fuel mixtures or similar fluids to be injected into the cylinder chamber of valve controlled internal combustion engines, control vanes are provided in close proximity to the valve retaining ring. The vanes deflect the flow of the air or air/fuel mixture without restricting the flow thus increasing the fuel flow coefficient. The vanes are curved to accommodate the fluid in-flow while ensuring controlled turbulence or angular momentum of the fluid in the cylinder chamber. The vanes can be arranged on a ring which is fastened in the inlet chamber in close proximity to the valve retaining ring.
