Novel device for visible-combustion experiment

Abstract

The invention discloses a novel device for a visible-combustion experiment. The novel device for the visible-combustion experiment comprises a bomb assembly, a view window assembly, an oil atomizer assembly, a pressure sensor assembly, an exhaust electromagnetic valve, a collision module assembly, a thermocouple assembly, an ignition plug assembly and an intake electromagnetic valve. A main body of the bomb assembly is a bomb body which is of a rectangular cavity structure. A simulation combustion chamber of the collision module assembly is fixed to the upper end of a locating rod through a locating pin. A locating hand wheel is installed at the lower end of the locating rod. By the adoption of the novel device for the visible-combustion experiment, the position of an oil atomizer in a view window can be adjusted accurately, the visible range can be fully utilized, and the usability of the device is improved; different types of simulation combustion chambers can be applied, a research is more similar to the actual work conditions of an engine, and therefore the credibility of research data is improved; besides, a heating wire is installed on the bomb body, the wall surface of the bomb body can be heated, the actual temperature of the wall surface in the process of combustion of the engine can be simulated, and therefore the credibility of the research data is improved.
