Embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings, so that those skilled in the art
The utility model can be better understood from and can be practiced, but illustrated embodiment is limited not as to of the present utility model.
Refer to shown in Fig. 2 ~ 5, it discloses the model gasoline engine for having a kind of heating wire igniting for having pre-heat effect, it has
There is a cylinder 10, the outer circumferential side of the cylinder 10 is provided with a heat dissipation head 11, a pad 15 is provided between cylinder 10 and heat dissipation head 11,
A combustion chamber 12 is provided with the cylinder 10 again, while the cylinder 10 is provided with the opening 101 communicated with the combustion chamber 12, the vapour
Cylinder 10 in the outer rim of opening 101 be interval with it is multiple connect hole 102, and the combustion chamber 12 includes a joint seat 13, and it was located at should
