Abstract: Natural gas automobiles have great economic benefit and environmental protection benefit. Because natural gas is in high pressure, it is in danger. The reasons of hidden troubles are analyzed in the high pressure gas spray of mouth of a bottle explosion, the drop of bottle hanging install, the leak of gas pipe and connection, the lose efficacy of the function of decompressing valve sealing, and so on. The prevention methods are put forward each reason respectively.
