Embodiment Construction
[0019] exist figure 1 In the shown embodiment, the cylinder head (1), the cylinder liner (2) and the piston (3) form a combustion chamber (4), and the pressure accumulator chamber (5) is arranged on the cylinder head (1). Between the accumulator (5) and the combustion chamber (4) there is a valve group (V 1 , V 2 ) two channels for opening and closing, the valve group (V 1 ) opens toward the pressure accumulator, and the valve group (V 2 ) opens towards the combustion chamber. Valve group (V 1 , V 2 ) depends on the pressure difference between the two chambers. Only when the resultant force of the pressure difference acting on the valve disc is greater than the spring preload, the valve will automatically open. In the initial stage of engine combustion, when the explosion pressure rises rapidly, the valve group (V 1 ) increases the total volume of the combustion chamber and curbs the sharp increase of the explosion pressure. When the piston descends, when the pressure o...
