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

Technical field: [0001] The invention relates to a constant volume combustion bomb device, in particular to a constant volume combustion bomb combustion product collection system and method. Background technique: [0002] As emission regulations become more and more stringent, people are paying more and more attention to how to effectively reduce the emissions of harmful gases from engines. It is important to study how harmful emissions such as PM are formed during the combustion process in cylinders to reduce their emissions. At present, a single-cylinder engine full-cylinder sampling system has been used in the current research, but the system has complex structure, long development cycle, high cost, and large cycle changes during operation. Because constant volume combustion bombs can accurately control a variety of thermodynamic parameters, they are widely used in the research of simulating engines, but the research work is mostly concentrated in the field of combustion. Ther...
