加强对汽车及压缩天然气装置的检查和维护工作，对提高装置技术性能及行长装置的使用寿命吸积极意义。压缩天然气装置的维修保养应到指定的维修站保养或者由专业人员操作。在车上拆卸时，就用棉布堵住管道口，以免杂质进入管路。
To strengthen the auto and compressed natural gas equipment inspection and maintenance work, to absorb positive significance improve performance and the service life of the device, device technology. Compressed natural gas equipment repair and maintenance should be to the designated repair station maintenance or by professional personnel. Removing in the car, use cotton block the pipe mouth, lest impurities into the pipe.
