ABSTRACT:
A gas vortex device for an internal combustion engine includes at least a guider body installed in a predetermined position of a flowing passage provided between an inlet chamber of a cylinder body and an exhaling end of an air inputting arrangement of the internal combustion engine. The guider body which has an inlet end and an outlet end installed in such a manner that the outlet end should be more proximate to the inlet chamber of the cylinder body than the inlet end. The guider body further has an axial portion and at least two guiding wings extending symmetrically, outwardly and radially from the axial portion. Therefore, a gas mixture including the air and the atomized fuel that are sucked into the flowing passage from the air inputting arrangement are forced to flow through the guider body, inhaling through the inlet end and exhaling from the outlet end thereof before sucking into the inlet chamber of the cylinder body, so that the gas flow is guided by the guiding wings to spin and speed up such whirling motion. Therefore the gas mixture sucking into the inlet chamber of the cylinder body is spinning continuously in vortex form, so as to further atomize the atomized fuel particles to more diminutive tiny particles and more evenly and completely mix the air and atomized fuel particles.
