To provide a combustion device, and an air-fuel mixture producer with a simple composition capable of producing an air-fuel mixture of a stable gas concentration, or an air-fuel mixture added with a particular additive.
The air-fuel mixture producer is composed of two chambers A and B separated by a diaphragm 4 having selective permeability of passing gas and not passing liquid. It is composed such that liquid is put in one chamber A of the two chambers, and air is continuously passed through the other chamber B to produce an air-fuel mixture of mixing vaporized gas of the liquid and the air, an injector 9 injecting a mist like or gas like additive is provided in a part of the other chamber B more downstream than the diaphragm, and a mixture of the air-fuel mixture and the additive is taken out from the other chamber B.
