Carmakers are shifting from V-8s to V-6s, and from 6-cylinder engines to 4-cylinder powerplants as they strive to improve fuel economy. For a valve supplier such as Eaton Corp., that means fewer valves per engine.

But the trend, accompanied by a surge in turbocharging, also is expanding demand for higher-performance valves and advanced valve actuation systems, says Scott Adams, senior vice president of product development, marketing and planning for Eaton Vehicle Group.

Adams notes Eaton is proficient in both areas. He predicts tougher fuel economy standards through 2025 will create a “very dynamic” powertrain market over the next decade.
