Embodiment Construction
[0021] Below by embodiment and in conjunction with accompanying drawing, the present invention will be further described:
[0022] like figure 1 As shown, a natural gas and hydrogen double injection device is mainly composed of a natural gas supply system, a hydrogen supply system, a control system, an engine 16 and a three-way catalytic converter 17. The engine 16 is used to burn natural gas and hydrogen, and output power externally; the three-way catalytic converter 17 is installed on the exhaust pipeline, and is used to convert hydrocarbons HC, carbon monoxide CO, nitrogen oxides NO X converted to water H 2 O, carbon dioxide CO 2 , Nitrogen N 2 and other harmless substances.
[0023] The natural gas supply system includes a high-pressure natural gas cylinder 1 , a first solenoid valve 2 , a first decompression regulator 3 and a natural gas rail nozzle body 4 connected by pipelines. Preferably, the high-pressure natural gas bottle 1, the first solenoid valve 2, the firs...
