ABSTRACT:
The present invention relates to an internal combustion engine, and more particularly, to an internal combustion having improved performance by promoting mixing of fuel and air using a fuel mixing means installed at an intake port to improve the flow property of the mixture introduced into a combustion chamber. In an internal combustion engine according to the present invention, a fuel mixing means is installed at an intake port for use in supplying a mixture of fuel and air into a combustion chamber. The fuel mixing means is provided with a stream-disturbing body having a plurality of vanes for disturbing a stream passing through the intake port. The stream-disturbing body is installed rotatably in the intake port to generate a vortex or turbulence so that fuel and air are mixed uniformly and then supplied into the combustion chamber.
