Car fuel tank with inner and outer vessels - has outer vessel in halves containing absorbent material and causing inner one to burst on collision

摘要

The outer vessel is in two halves of breakable plastics. In the case of a collision, the outer vessel transmits the forces acting on it, via mountings to the inner vessel, destroying the latter in the process. The fuel emerging from the inner vessel is absorbed and rendered difficult to ignite by material housed in the space between the vessels. ADVANTAGE - Increased protection against fuel escape and ignition when tank is damaged from whatever cause.
