Abstract
A number of embodiments of induction systems for internal combustion engines having fuel injector which spray fuel into the intake passages serving the individual combustion chambers. An arrangement is provided for injecting auxiliary air into the intake passages at atmospheric pressure. The timing and duration of air injection is varied so as to reduce pumping losses, control internal EGR, induce turbulence in the combustion chamber, control idle speed and to atomize the fuel injected by the fuel injectors, and, if desired, redirect it. Various valving and timing arrangements are disclosed whereby the duration and timing of the air injection can be controlled. In addition, embodiments are disclosed having insert pieces through which the fuel is injected and redirected by the air injected.
