Abstract
A combustion promoter operating unit, in which a pressure-receiving piston (6) is provided on a cylinder head (2) or a piston (3) in an internal combustion engine. The piston (6) is moved toward a combustion chamber (4) up to an upper dead point by a hydraulic pressure to supply compressed air to a smaller cylinder (8). When the piston (6) has moved beyond the upper dead point, the hydraulic pressure is released, so that a smaller piston (7) fixed to the piston (6) is moved in the opposite direction by the pressure in the combustion chamber (4). At the same time, the air in the smaller cylinder (8) is ejected into the combustion chamber (4) to apply a turbulent flow to the combustion flames, whereby the combustion of the gaseous mixture is promoted.

Although there are other methods, such as the occurrence of stale or turbulent flow before the start of combustion or early in the start of combustion, combustion in a lean state is possible, but the combustion speed is low and the combustion temperature is low, so a significant effect can be obtained. Did not. This is because there was no good means to generate turbulence in the high-pressure flame after the start of combustion because the turbulent flow was applied before the start of combustion or at a low combustion temperature.
