PURPOSE:To improve the ignition of mixture by a method wherein a narrowing member is provided at the vicinity of the injection port of a fuel pipe and flow velocity thereof is decreased by releasing of the given amount of the mixture. CONSTITUTION:The part of the mixture of fuel injected from the injection port 7 of the fuel pipe 5 and air is reduced by a collar 18 and it is blown off between jet 13 and jet 14 under condition of thin jet 24 passing through between the collar 6 and the collar 18. The energy of the thin jet 24 is lost at a short distance after blowing between the jet 13 and the jet 14 and it is involved to the direction of an arrow sign 25 and 26 respectively. According to this method, the mixture having high density and low speed is generated steadily between the jet 13 and the jet 14 and the ignition of the mixture may be effected under easy and the stable condition.
