Abstract
The invention discloses a gas control ejector of a compressed hydrogen automobile, pertaining to an automobile gas control ejector. A high-pressure hydrogen storage bottle (1) is connected with a master valve (2) and a pressure reducing valve (3) by a gas pipe and the pressure reducing valve is connected with a fire arrester (4) by the gas pipe and then passes through two gas pipes in parallel. One gas pipe (5) is connected with a low-pressure hydrogen storage bottle (7) by a one-way valve (6) and connected with an auxiliary ejector nozzle (12) by the gas pipe while the other gas pipe (24) is connected with the internal cavity of a syringe (18) of a main ejector by the one-way valve (23) and a gas path (9). A main ejector nozzle (13) is connected with a hydrogen-oxygen mixer (14) by the gas pipe and a one-way valve (16) while the hydrogen-oxygen mixer is connected with an engine (15) by the gas pipe. The gas control ejector has simple structure, convenient use, flexible operation performance and reliable safety. An injection valve is utilized to control the ejection of compressed hydrogen gas and ensure that the hydrogen gas enter the engine for burning after the mixture with oxygen gas, thereby saving fuel gas and leading automobiles to achieve better operation performance.
