Natural gas supply system for vehicle engine experiment

摘要

The present invention can improve the safety of the natural gas supply system, and relates to a natural gas supply system for an engine engine experiment for expanding the application range to supply a variety of pressure to the experimental engine.;1 is a cylinder 1 for compressing and storing natural gas in a liquid state, and a vaporizer for vaporizing natural gas in a gas state through a conversion valve 2 in the cylinder 1 as shown in FIG. (5) is installed, the safety valve (7) and the ventilation valve (8) is installed in the vaporizer (5) connected to the vent line, and the emergency shut-off valve (9) that can respond to the emergency situation inside the cell is installed The regulator 12 and the bypass line 12 'are installed at one end of the line 9' drawn out from the emergency shutoff valve 9, and the pressure lowered at one end of the final part of the line 9 '. A low pressure regulator 16 and a pressure gauge 16 ′ capable of boosting the pressure may be installed, and a ball valve 17 may be installed to manually control the supply of natural gas to the experimental engine.;Therefore, according to the present invention, the safety of the natural gas supply system can be improved, and the scope of the engine experiment can be extended, so that the experiment of the natural gas engine in the development process can be effectively performed.
