A Novel Design and Computational Fluid Dynamics of Swirl Flow Enhancing Device in Intake of IC Engine

The present paper work is directed to a device located at the intake port at the junction of the intake manifold and the engine head. This location allows the device to be used with any type of carburetor or fuel injection system. It is the object of the present device to utilize at least three fixed, helically twisted blades to impart additional swirl mixing of the fuel/air mixture. This fuel/air mixture has already been pre-heated by its travel through the intake manifold. The "violent swirl" created by the device provides a more uniform fuel/air mixture, thereby causing a more complete and efficient combustion. The overall result of using the device is better gas mileage, increased performance, easier starting, and less pollution. The object of the project work to improve the fuel/air mixture of the fuel injected engines, preventing valves from being burned or eroded by clogged injectors. As a result of forcing the air to enter the intake port in a high velocity swirl, there is disruption of any direct fuel streams upon the head of the cylinder intake valve which occur as a result of clogged injectors. Another object of the project work is to provide a device that improves the homogeneity of the fuel/air mixture delivered by the carburetor to the cylinders of an internal combustion engine with little or no obstruction in the mixture flow resulting in no starving of the engine. Another object to deliver the fuel/air mixture to the center of the cylinder for a uniform flame front. The swirling mixture delivered by the present invention results in cleaner, more-efficient combustion.
