CNG cylinders also require regular safety inspections and maintenance to ensure their safety and reliability during use. This includes inspecting the appearance, valves, sealing, and necessary cleaning and anti-corrosion treatment of the gas cylinder. CNG cylinders are an essential component of clean energy vehicles, providing important technical support and guarantees for achieving green travel and reducing carbon emissions.

CNG cylinder, also known as compressed natural gas cylinder, is a container specifically designed for storing gaseous natural gas under high pressure. CNG, as a clean energy source, is widely used in the fuel systems of vehicles such as cars, buses, and taxis. CNG cylinders compress natural gas to a certain volume through high pressure for storage and transportation. CNG cylinders are filled with compressed natural gas through specialized refueling equipment and provide fuel to the engine through the vehicle's gas supply system. Due to its high combustion efficiency and low emissions, vehicles using CNG as fuel have significant environmental and economic advantages.
