Toyoda Gosei develops new fuel tank cut-off valve

摘要

Toyoda Gosei Co., Ltd. has developed a cut-off valve with a novel structure that contributes to a lighter vehicle weight. This cut-off valve is being used on the new Land Cruiser from Toyota Motor Corporation. Cut-off valves are plastic components of fuel tanks that prevent elevation of the internal pressure, which - if excessive - can lead to rupture of the tank, by releasing vaporized gasoline as the temperature in the tank rises. Gasoline more readily vaporizes in regions such as the Middle East, where temperatures are high, and in mountain areas where the atmospheric pressure is low. Higher ventilation performance is needed in such places.
