Exhaust gas that has entered through an exhaust outer cylinder exhaust inlet 1C is divided into two, and straight exhaust enters the inner cylinder 2 from an inner cylinder exhaust inlet 2C and is blocked or blocked by an accelerating umbrella 2E. It diffuses and the pressure rises. On the other hand, the exhaust that has entered the acceleration path 1F between the inner cylinder and the exhaust outer cylinder 1 is accelerated in a narrow space, and negative pressure is generated. Thereafter, the gas is discharged from the exhaust outer cylinder outlet 1D. At this time, the exhaust in the inner cylinder is sucked and discharged from the exhaust passage hole 2A.

FIG. 1 is a three-dimensional perspective sectional view of the exhaust promotion device of the present application. The exhaust that has entered from the exhaust outer cylinder exhaust intake (1C) is divided into two. The straight exhaust gas enters the inner cylinder (2) from the inner cylinder exhaust inlet (2C) and is blocked or blocked by the accelerating umbrella (2E) and diffuses, and the pressure rises. On the other hand, the exhaust that has entered the acceleration path (1F) between the inner cylinder (2) and the exhaust outer cylinder (1) is accelerated in a narrow space, and negative pressure is generated. Thereafter, the gas is discharged from the exhaust outer cylinder outlet (1D). At this time, the exhaust in the inner cylinder (2) is sucked and discharged from the exhaust passage hole (2A). The rear end portion of the exhaust outer cylinder outlet (1D) is widened toward the outside to achieve infinite exhaust jet diffusion.
