Eaton Launches Next-Generation Hollow-Head Valves for Improved Engine Efficiency
24.3.2021 14:30:00 EET | Business Wire | Press release
Power management company Eaton today announced its Vehicle Group has introduced its next-generation sodium-filled hollow-head valves, which improve fuel economy, reduce emissions and increase performance in gas-powered engines. The valves feature a unique design that lowers the cylinder chamber temperature while mitigating engine knock.

Unlike traditional hollow valves, the head portion of the new valves is composed of two separate sections that are welded together during the production process. This enables higher flexibility in the sodium cavity design, increasing volume and assuring optimal sodium flow. The welding design and its tested technology ensure the valves comply with the most demanding industry validation targets.
“The new generation of Eaton valves represents the next step in valve evolution and will provide solutions customers are asking for,” said Pawel Wolski, business unit director, Valvetrain, Eaton’s Vehicle Group. “Eaton continues to provide solutions to its customers as vehicle emissions become increasingly stringent.”
As international emission standards for vehicles tighten, it has led to new homologation cycles and the limiting of emissions worldwide. In the near future, regulations on fuel consumption are expected to be even more demanding, forcing manufacturers to design engines with higher air-to-fuel ratios or reconfigure the entire engine calibration map.
The new valves have the capability to cool down the combustion face and, therefore, the chamber temperature, which increases the spark advance and air-to-fuel ratio because the engine is less inclined to knock. As a result, the brake specific fuel consumption (BSFC) can be increased and emissions reduced.
The new valves have undergone several tests for durability and performance, including:
- Welding fatigue
- Overspeed durability
- Abusive dynamic durability
- Full-power/ Full-load durability
- Thermometric analysis
- Knock limit characterization
- Brake specific fuel consumption measurement
Eaton’s next-generation sodium-filled hollow-head valves are currently being evaluated by several global automakers, with start of production scheduled for 2023.

Forrester’s 2027 European Predictions: Despite A Strong Desire To Regain Its Digital Sovereignty, Europe Will Selectively Reset, Not Sever, Key Technology Relationships30.9.2026 14:33:00 EEST | Press release
According to Forrester’s (Nasdaq: FORR) 2027 European predictions, unveiled today at Forrester’s Technology & Innovation Forum EMEA, Europe will enter 2027 determined to recover its digital autonomy, but the gap between its ambition and control will widen. More than half of European companies embracing AI will reduce their dependence on US hyperscalers due to sovereignty concerns, moving their critical data and applications to European providers. A lack of end-to-end sovereign alternatives, however, will require consumers, companies, and policymakers to pursue selective digital autonomy, which consequently will reshape consumer behaviours, cloud choices, mobility, resilience, and trade strategy with China. Forrester’s Predictions reports offer forward-looking insights into trends to help executives and their teams anticipate change, reduce uncertainty, and make confident decisions ahead of market shifts. Key highlights from the Europe 2027 predictions include: China will trigger manufa
