TANK FOR STORING COMPRESSED NATURAL GAS

摘要

A tank for storing compressed natural gas (CNG) for fueling an automotive vehicle engine. The tank includes a container body for containing the CNG at a service pressure rating from about 20 MPa (megapascals) to about 30 MPa, the container body being formed from a single piece. The container body includes a head end region, a terminal end region distal to the head end region, and an intermediate region extending therebetween. The terminal end region and the head end region define an axial length of the container body. The container body is formed from an aluminum alloy. A valve member is operatively connected to, and in fluid communication with the container body via an opening defined in a wall of the container body. The container body wall has a thickness ranging from about 3 mm to about 10 mm.
