Combustion chamber for reducing knocking intensity of internal combustion engine and inhibiting super knocking of internal combustion engine

Abstract

The invention discloses a combustion chamber for reducing knocking intensity of an internal combustion engine and inhibiting super knocking of the internal combustion engine. According to the combustion chamber, a plurality of arrayed wave absorbing small holes are formed in the positions of a cylinder cover and a piston, pressure disturbance formed in a cylinder is attenuated and eliminated in time, and therefore the knocking intensity is reduced; and on the other hand, wall surface wave absorbing small holes inhibit pressure disturbance formed in the initial stage, so that the risk of secondary spontaneous combustion and even detonation can be reduced, and the formation of super knocking in the internal combustion engine is inhibited. According to the combustion chamber for reducing the knocking intensity of the internal combustion engine and inhibiting the super knocking of the internal combustion engine, only the surfaces of the cylinder cover and the piston need to be machined, under the condition that operation parameters and structural parameters of an engine are not changed, the super knocking is restrained, the knocking intensity is reduced, manufacturing and improvement are convenient, cost is low, products can be manufactured after design is completed, popularization is easy, the compression ratio of the engine can be further improved, so that the heat efficiency of the engine is further improved.

Description

technical field [0001] The invention belongs to the field of engines and relates to a combustion chamber for reducing the knock intensity of an internal combustion engine and suppressing super knock of the internal combustion engine. Background technique [0002] Facing the increasing shortage of non-renewable energy and increasingly stringent emission regulations, the engine, as the main energy conversion device for human production and life, is facing tremendous pressure for innovation, and it is urgent to further improve thermal efficiency. According to the thermodynamic cycle theory, the most effective way to improve the thermal efficiency of the engine is to increase the compression ratio of the engine. However, further increasing the compression ratio of the engine will aggravate the knock intensity of the engine, and even lead to the formation of super knock. High-intensity knocking will destroy the components of the engine combustion chamber in a short period of tim...

Problems solved by technology

However, on the one hand, these technologies need to increase a large amount of cost, on the one hand, the performance of the engine may be lost, and on the other hand, the super knock cannot be completely suppressed when the compression ratio is further increased.
