Among the components produced by the company’s Global Valvetrain business are sodium-cooled valves with exceptionally small stem diameters that deliver both reduced weight and greater resistance to the high temperatures that can be a limiting factor in highly rated downsized engines.

The extreme valve temperatures experienced on today’s highly boosted downsized engines can lead to reduced valve fatigue life and critical valve guide and stem seal temperatures, resulting in the need for expensive valve steel alloys. The valve guide is the main heat path from the valve stem to the cylinder head.

Eaton said that a series of process improvements and new engine valve product designs will help engine manufacturers address issues related to engine downsizing to achieve better fuel economy and reduced emissions. When alloy choice alone is not enough to handle thermal loads, Eaton offers a full range of internally cooled engine valves.

Continuing Opel’s strategy of downsizing, a new 103 kW/140hp 1.4 Continuously variable valve timing is featured in all engines on both inlet and exhaust sides, except the 1.6-liter The new, downsized 103 kW/140 hp 1.4-liter The 74 kW/100 hp entry-level version in the gasoline line-up consumes 5.5 gasoline engines. liter turbo.
