Technical field
The present invention relates to technical field of energy equipment, a kind of device for detecting the gas leakage of fluid pressure type CNG gas cylinder.
Background technology
Gas-fueled vehicles are to change the natural gas a kind of gaseous fuel automobile as fuel with oil, are called for short CNG automobile.Natural gas first
Alkane content, typically more than 90%, is a kind of well automobile engine fuel.Natural gas has the advantage that as fuel
(1) flameholding, will not produce pinking, and cold and hot starting is convenient;(2) compressed natural gas accumulating, decompression, burning is all strictly
Sealing state under carry out, be not susceptible to reveal, additionally its gas bomb is through various special destructive testings, safe and reliable;
(3) compressed natural gas combustion completion, carbon distribution is few, reduces vapour lock and pinking, is conducive to extending the service life of each parts of electromotor,
Reduce maintenance number of times, maintenance cost is greatly lowered;(4) oil consumption of electromotor can be reduced;(5) pressure is used
Contracting natural gas, compared with gasoline, can be greatly lowered, carbon monoxide, sulfur dioxide, the discharge of carbon dioxide etc., and does not has
Benzene, lead etc. is carcinogenic and noxious substance is detrimental to health.Based on above-mentioned advantage, what some cities started popularization and application is to distinguish
Use compressed natural gas or gasoline compressed natural gas-gasoline dual-purpose fuel automobile, the most also will widely popularize the single fuel sky of application
So gas automobile.
