Eaton introduces next-generation fuel tank isolation valve for hybrid electric vehicles

March 25, 2024

Eaton has launched its next-generation fuel tank isolation valve (FTIV) for hybrid vehicles.

The new FTIV® is designed to be easier to mount, is 27% lighter, 39% smaller, and contains 24% fewer components than its predecessor. This development comes as hybrid vehicles are becoming a popular alternative to fully electric vehicles, and Eaton’s isolation valve aims to reduce packing challenges with its reduced dimensions.

The company’s engineers have reduced the size of the FTIV by 39% by improving the magnetic force produced by the isolation valve while simultaneously reducing the amount of copper used. The new FTIV is designed to be easier to mount in a variety of challenging tank configurations within the vehicle.

Eaton is also participating in a joint program with Tatra Trucks, a Czech truck manufacturer, to produce a specialized off-road electrified truck, called the Battery Electric Tatra Truck with Multi-speed Transmission (BETTT). Eaton will integrate its power distribution unit (PDU) and award-winning 4-speed transmission for medium- and heavy-duty electrified vehicles (EVs).

Eaton mentioned it has agreements to supply its next-generation FTIV to two global automotive customers and has drawn interest from other manufacturers.

Christy Roadknight, Business Unit Director, Eaton’s Mobility Group, said, “Pressure builds up in the gas tank when the vehicle is in electric mode, so that pressure has to be released. Also, when refueling you want to make sure the tank is depressurized to avoid spit back, (…) Modern hybrids spend more time in electric mode so FTIV is now even more important.” She also added, “We optimized the geometry on existing components and ensured the new and improved design maintained the reliability of our previous offering. This market is expanding, and we have a 13-year history in this space.”
