Type I: It is often used in stationary applications, such as industrial gas storage, and for vehicles with minimal weight restrictions, like buses and heavy trucks.
Type II: It is suitable for both industrial and vehicular applications where a balance between weight and cost is needed, such as medium - duty trucks or fleet vehicles.
Type III: It is mainly used in vehicles where weight reduction is required and the cost is acceptable, such as some high - end commercial vehicles or vehicles with strict weight requirements.
Type I: Type I CNG cylinders are the most cost-effective option， because of its simple material and manufacturing process, also the most commonly selected type.
Type II: Its cost is higher than that of type I due to the use of composite materials, but it is more cost - effective than type III.
Type III: Mady by the aluminum liner fully -wrapped with carbon fiber are much lighter than Type I and II, Type III cylinders have a benign leak - before - burst feature, which eliminates the possibility of catastrophic failure during operation and ensures safety.
