The device can effectively carry out the testing and research of in-cylinder air flow, jetting, initial temperature and pressure, initial air distribution and fuel types, is low in cost of constant volume bombs, is simple in operation, and is high in testing efficiency.

Description

technical field [0001] The invention provides a multifunctional combustion test device, in particular to a multifunctional combustion test device and a test method for simulating engine conditions, belonging to the field of internal combustion engines. Background technique [0002] With the rapid increase in the number of automobiles, automobile emissions have aggravated the pollution of the atmosphere and the deterioration of the environment. Automobile emissions have become the main source of urban air pollution. Reducing engine pollutant gas emissions has become one of the important issues to be solved for the continued development of internal combustion engines. Various problems caused by the increasing consumption of traditional fossil energy cannot be ignored. Therefore, at present, energy saving and emission reduction has become the main topic and direction of the development and research of internal combustion engines. Optimizing the combustion in the cylinder of int...

Problems solved by technology

However, the combustion factors were oversimplified in the study of the constant volume bomb, which is quite different from the actual combustion situation in the actual internal combustion engine cylinder. The flame generally starts to develop from the center of the constant volume bomb, and only the initial combustion temperature can be studied. , pressure, fuel type and other changes on the combustion
