Abstract

The invention relates to a system and a method for collecting the combustion products of a constant volume combustion bomb, aiming at overcoming the defects of a single-cylinder engine all-cylinder sampling system and the traditional gas collecting device and method. The system for collecting the combustion products of the constant volume combustion bomb comprises a constant volume combustion bomb, a quenching device, a first electromagnetic valve, a first flow metering valve, a second electromagnetic valve, a second flow metering valve, a third electromagnetic valve, a third flow metering valve, a gas bag or gas cylinder, a nitrogen steel cylinder, a synchronous data acquisition system and a singlechip control system. The system and the method have the advantages and the beneficial effects that multiple thermodynamic parameters can be accurately controlled by the constant volume combustion bomb, so that the combustion under various conditions can be accurately reproduced, and the influence of actual cyclical variation of an engine to sampling can be eliminated.

Description

[0001] Technical field: [0002] The invention relates to a constant-volume incendiary bomb device, in particular to a system and method for collecting combustion products of a constant-volume incendiary bomb. [0003] Background technique: [0004] With the increasingly stringent emission regulations, people are paying more and more attention to how to effectively reduce the emission of harmful gases from the engine. It is of great significance to study how harmful emissions such as PM are formed during the combustion process in the cylinder to reduce their emissions. At present, a single-cylinder full-cylinder sampling system has been used in research, but the system has complex structure, long development cycle, high cost, and large cycle changes during work. Because constant-volume incendiary bombs can precisely control various thermodynamic parameters, they are widely used in the research of simulated engines, but most of the research work is concentrated in the field of c...
