Description

technical field

[0001] The invention relates to the field of fuel premixed combustion characteristic research and testing devices, in particular to a high-pressure gas generator and a high-pressure and accurate combustion characteristic testing system. Background technique

[0002] Fuels (such as hydrogen, methane, acetylene, gasoline, etc.) are the cornerstone of social development and an important source of energy in human production and life. Understanding the premixed combustion characteristics of various fuels is crucial to how to better apply or control combustion . For example, on the basis of fully grasping the combustion characteristics of fuel, controlling and optimizing the combustion process can improve the power performance and fuel economy of internal combustion engines, and control the emission of pollutants.

[0003] When studying the premixed combustion characteristics of fuel, the stoichiometric ratio at the initial moment, the initial pressure, the initia...
