ABSTRACT:
An intake system for internal combustion engines 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 opposed relation with the injection valve and a hollow valve body mounted in the intake pipe for movement in the 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 stationary valve body includes a frusto-conical portion and a cylindrical portion, of which lower edge is in the form of sinusoidal wave to cooperate with the hollow valve body in producing the valve opening of gradually increasing opening area.
