Abstract

The invention relates to the field of engines, in particular to a combustion organization method and system for restraining gasoline engine knocking. A combustion organization method for restraining gasoline engine knocking comprises the steps that ammonia gas is sprayed into an air cylinder, so that high-spontaneous-ignition-point fuel mixed gas is formed around the wall of the air cylinder; gasoline is injected into the air cylinder, so that high-energy-density fuel mixed gas is formed near a sparking plug; the high-spontaneous-ignition-point fuel mixed gas and the high-energy-density fuel mixed gas form layered mixed gas in a gasoline engine cylinder; wherein the high-spontaneous-ignition-point fuel is ammonia gas, and the high-energy-density fuel is gasoline. According to the combustion organization method and system, the gasoline-ammonia layered mixed gas is formed in the gasoline engine air cylinder, the gasoline-air mixed gas is distributed in the peripheral area of the spark plug, the ignition process and the development of fire cores are facilitated, and therefore the combustion quality is guaranteed; in the tail end high-temperature unburned area where spontaneous combustion is prone to occurring, the spontaneous combustion tendency of mixed gas is reduced due to the existence of ammonia gas, and therefore knocking is restrained.

Description

technical field [0001] The invention relates to the field of engines, in particular to a combustion organization method and system for suppressing gasoline engine knocking. Background technique [0002] With the advancement of the "dual carbon" goal, the engine field is facing many challenges, and the technical development of the engine is constantly progressing in the direction of low carbonization and high efficiency. With the popularity of small supercharged engine technology, the compression ratio of the engine is getting higher and higher, and the requirements for thermal efficiency are also getting higher and higher. The biggest problem hindering the improvement of engine thermal efficiency is the knocking problem of gasoline engines. The knocking problem of the gasoline engine is caused by the spontaneous combustion of the unburned gas at the end under the influence of high temperature and high pressure before the arrival of the flame front. The violent spontaneous co...
