Abstract

PURPOSE:To keep almost constant the quantity of air ejected from an induction passage, by placing a gas source for the induction passage, downstream to a primary throttle valve but upstream to a secondary throttle valve. CONSTITUTION:An induction pipe 83 communicates with a passage 84 and a gathering passage 85. The induction passage 83 communicates with the downstram side of a primary throttle valve 25 through a hole 89 and a passage 88 and with the immediately upstream side of a secondary throttle valve 38 through a passage 84 and a jet port 91. For these reasons, the quantity of gas which is ejected from the induction passage 83 into a combustion chamber is kept almost constant regardless of the change in the state of operation. As a result, the fall in the flame propagation velocity in the medium and high speed ranges is avoided to suppress the generation of unburned hydrocarbon.
