With the rapid consumption of limited oil resource, natural gas has become the increasingly popular alternative fuel for vehicles. For instance, CNG vehicles powered by natural gas are highly recommended as one of the high impact green environmental protection projects in the world. These CNG vehicles cut down costs, economize resources, and further reduce exhaust pollution to the environment. Our CNG Aluminum Alloy Lined Cylinders Fully Wrapped with Carbon Fiber are designed for CNG vehicles (buses, compact cars, etc.). The cylinders offer advantages of low temperature toughness, fatigue resistance, low weight and high safety. Compared with the CNG Steel Lined Hoop-Wrapped Cylinder for Vehicles, CNG Aluminum Alloy Lined Cylinders Fully Wrapped with Carbon Fiber for vehicles are much lighter, up to 50% lighter in weight.
