<p>The present invention relates to a valve guide for an internal combustion engine, and more particularly, to a swirling valve guide having a fuel mixing means installed on an outer peripheral surface of the valve guide, which protrudes into an intake port of an internal combustion engine, to promote mixing of fuel and air. According to the present invention, there is provided a swirling valve guide including a guide portion installed to protrude into an intake port of a cylinder head of an internal combustion engine for guiding reciprocation of an intake valve of the internal combustion engine, comprising a fuel mixing mean having a member installed on an outer peripheral surface of the guide portion to mix fuel and air passing the intake port and to produce a swirl in a mixture of the fuel and air at a downstream side of the flow of the mixture. With the present invention, the fuel mixing means is installed on the valve guide adjacent to a combustion chamber to produce a swirl so that a mixture of fuel and air can be introduced into the combustion chamber in a state where the fuel and air are appropriately mixed with each other, hi addition, the fuel mixing means is installed on a conventional valve guide to minimize a disturbance of the flow of the mixture.</p> |
