ABSTRACT:
An intake system for an internal combustion engine comprises a throttling system mounted in an intake pipe between a fuel injection valve and an intake manifold, the throttling system including a stationary valve body fixed in the intake pipe in opposition to the injection valve and a hollow valve body mounted in the intake pipe movably in an axial direction of the intake pipe. The hollow valve body has a downwardly converged inner wall surface surrounding the stationary valve body to define therebetween valve opening of variable opening area. The axial movement of the hollow valve body causes the change in the opening area of the valve opening to control an amount of air-fuel mixture charged therethrough into the engine.
