·The initial industrialization conditions of natural gas vehicles are mature

The technology of natural gas vehicles in China has matured and can basically be industrialized, but the standardization construction is seriously lagging behind, and some current standards are obviously aging.

From the perspective of the standard system of LNG vehicles, China's natural gas vehicle standard system is complete, involving basic standards, vehicle standards, engine standards, special equipment standards, gas cylinders and accessories standards, temperament standards, gas filling standards, and gas filling. Eight areas, including station standards, cover all aspects of the LNG automotive industry. How to complete the preparation of various standards in the system table as soon as possible and promulgate and implement it requires more efforts.

Standardization construction is crucial to the development of the industry. The lack of standards and lag are the bottlenecks restricting the development of the industry. With the development of the natural gas automobile industry, some of the standard technical indicators promulgated and implemented many years ago are now aging and need to be revised. Moreover, some of the standard projects formulated by foreign standards have been used to verify that they are not completely matched with Chinese products through experimental verification, and their operability needs to be improved. In addition, the domestic standard system lacks systematic technical specifications for gas vehicle parts. Natural gas vehicle standards need to be further developed or revised.

At present, there are three natural gas vehicle technical standards revised in China, namely, "Manual Cut-Off Valves for Gas Vehicles", "Installation Requirements for Gas-Fired Vehicles", and "Test Methods for Fuel Consumption of Compressed Natural Gas Vehicles". In addition, the "Natural Gas Vehicles and LPG Car Vocabulary", "Natural Gas Vehicles and Liquefied Petroleum Gas Vehicles", "CNG Compressed Natural Gas Vehicles" and "Technical Conditions for Special Equipment for Compressed Natural Gas Vehicles" have been included. The revised plan of the Institute of Standardization. Standards such as "Gas Fuel Consumption Material Limits", "LNG Car Safety Valves", "Gas Vehicle Refit Technical Requirements", "LNG Vehicles Bottle Valves", and "LNG Vehicles Globe Valves" have also been listed. Into the plan to provide a basis for the development of the natural gas automotive industry.
