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...

Abstract

A combustion system of IC engine for decreasing the pressure raising rate in cylinder and lowering the maximal explosion pressure features that a pressure accumulating chamber controlled by valve is arranged in cylinder cover. When the explosion pressure is suddenly increased, the pressure accumulating chamber is opened to suppress the maximal explosion pressure. Its advantages are high compression ratio, combustion efficiency and output power, and low oil consumption and noise.

Description

technical field [0001] The invention relates to a combustion system of an internal combustion engine which reduces the rising rate of pressure in a cylinder and reduces the maximum explosion pressure, and belongs to the field of engine combustion. Background technique [0002] At present, reciprocating internal combustion engines mainly include gasoline engines and diesel engines. It is generally believed that further increasing the compression ratio can improve the working efficiency of the engine. For gasoline engines, the compression ratio is relatively low, and if the compression ratio exceeds 10, it is prone to abnormal combustion such as deflagration, which makes the engine work unstable and performance decline. The compression ratio of the diesel engine is relatively high, but with the further strengthening of the engine, the emergence of high-speed, high-speed superchargers, the mechanical load and thermal load of the engine increase, which also limits the further im...
