PURPOSE:To mix a vaporized fuel with combustion air in an ideal manner to produce a mixed gas by opening a fuel ejection port of a vaporizing device in a vaporizing chamber and forming an annular air inlet path around the outer periphery of a combustion cylinder, and also forming a large number of air inlet holes in the combustion cylinder under irregular conditions with respect to the number, configuration, place and the like. CONSTITUTION:A vaporized fuel passes through a space formed between a vaporizing pipe 20 and a vaporizing glow plug and ejected through an ejection port 25 into a vaporizing chamber 7. Combustion air is introduced through an air intake port 12 into the combustion cylinder and blown into a combustion chamber 6 through air inlet holes 17 via an annular air inlet path 27, formed between an outer cylinder 14 and a combustion cylinder 11. The air inlet holes 17 are formed under an irregular condition with respect to the combustion cylinder 11. Combustion air is blown into the combustion chamber 6 under an unbalanced state in the position, inflow quantity and inflow speed and the like, and is formed into a turning or turbulent state and the pressure distribution undergoes a change. Therefore, a part of combustion air is liable to be introduced into the vaporizing chamber 7. Accordingly, combustion air is blown into the combustion chamber 11 under an ideal state, and mixed with the vaporized fuel to produce a mixed gas. |
