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.

Description

Technical field [0001] The invention relates to a constant volume combustion bomb device. Specifically, the invention relates to a new type of combustion visualization experiment device. The invention is suitable for the fields of engine combustion visualization research, gaseous and liquid fuel basic combustion characteristics research and the like. Background technique [0002] The study of basic combustion characteristics of fuels is an important means of combustion scientific research. It is of great significance for exploring the reaction mechanism of fuels and developing new fuels. It plays a pivotal role in the technological progress of internal combustion engines and aircraft engines.
