PURPOSE: A structure of a fire hole for an engine is provided to prevent loss of inertia mass and vibration since a reciprocating part is removed from an engine and parts including a valve driving unit and a crank shaft can be removed. CONSTITUTION: A structure of a fire hole for an engine is as follows. A hollow cylinder is fixed to a cylinder head. A hole is formed on a part facing the combustion space of the cylinder, the side of the cylinder. A rotating unit is inserted into the cylinder so that the rotating unit can rotate maintaining air-tightness to the cylinder. A groove is formed on the side of the rotating unit and is selectively exposed through the hole and high temperature and pressure gas after explosion is temporarily stored. |
