INERGY offers a wide range of innovative and efficient solutions that control fuel behavior, soften slosh impact and reduce the noise generated by fuel systems, to comply with the more stringent noise requirements of hybrid vehicles and increase passengers' comfort.

Noise reduction is a key challenge in modern automotive design: acoustical treatments can increase vehicle weight up to 200 kg. Acoustical requirements extend to low & mid range vehicles as well.

As noise levels from the more obvious sources are reduced, more subtle noises are unmasked, even more noticeable on hybrid vehicles when operating in electric mode: not only aerodynamics and road noises but also fuel related noise, especially the noise caused by the fuel waves’ motion inside of the tank.

INERGY has developed a complete slosh noise reduction approach for the diagnosis and quantification of slosh noise sources.

This approach is essential for future performance improvements and has led to the development of the INBAFFLE family of noise reduction solutions that soften the slosh impact, introduce fuel damping.

With this new products range including natural and inserted baffle, INERGY anticipates future acoustic constraints linked to hybrid vehicles.

All INBAFFLE solutions are customizable to OEM’s requirements and specifications: INERGY baffles are adapted on a case by case basis depending on the design and application of each fuel system. 

INERGY slosh noise solutions can be integrated

• on assembly line (spring loaded or clipped baffles)

• or during the blow-molding process (patented innovation)

With INBAFFLE, INERGY offers a family of technical solutions to solve slosh noise problems.

This new process allows INERGY to integrate a large injection-molded baffle inside of the tank and weld it during the blow-molding process.
