とする容積可変副室付内燃機関。 Using a damping piston that changes the volume of the pre-chamber with each engine drive cycle based on the balance between the pressing force due to the cylinder gas pressure of the combustion chamber and the elastic force of the spring, the combustion pressure is increased or decreased by increasing or decreasing the volume of the combustion chamber. In an internal combustion engine with a variable volume auxiliary chamber to be adjusted, the volume increase operation start pressure received by the pressure receiving surface of the damping piston is set to a value close to the compression peak pressure of the engine, and the full stroke position pressure received by the pressure receiving surface is equal to the compression peak pressure of the engine. An internal combustion engine with a variable volume subchamber, characterized in that the elastic force of the spring is set to be at least twice the peak pressure.
