Abstract:
An induction system for an internal combustion engine having at least a pair of relatively movable components that define a combustion chamber, said induction system supplying a charge to said combustion chamber, said induction system forming an intake passage in which a throttle valve is positioned, said intake passage communicating with said combustion chamber through an intake port, said throttle valve being positioned in close proximity to said intake port and controlling the flow only to said combustion chamber, a fuel injector for injecting fuel directly into said intake passage for only said combustion chamber and a buffer valve in said intake passage and which is opened by the flow therethrough only to said combustion chamber for restricting the air flow upon sudden changes in position in said throttle valve so as to maintain a more uniform air fuel ratio under transient conditions.
