Abstract

PURPOSE: To generate a strong turbulence in the combustion chamber at the low speed and low load driving time, and to promote the carburetion while the chaging efficiency at the high speed and high load driving time is securing, by means of improving an air inlet device from a carburettor up to the combustion chamber.
CONSTITUTION: The mixed gas formed in a carburettor 11 at the operation time of an engine, is sent to a turning flow generator 13 via an air inlet pipe 10. Here, the mixed gas proceeds in a screw shape while it is pushing on the inner surface of an inner pipe 14 opposite side with ejection holes 17, by means of ejecting the air supplied to a ring chamber 16 via an air supplying tube 18 from an air pump facing on the central axis line of the inner pipe 14, and of allowing the ejecting holes 17 to be arranged in a screw shape, and a turning flow is generated in said device 13. Then, this mixed gas flows into a combustion chamber 4 via an air inlet port 5 while it is turning, thereby a strong turning flow is generated in the combustion chamber 4.
