What's Happening?
Nissan has introduced valve seats manufactured using cold spray technology in its new e-Power dedicated engine, marking a world-first application in automotive engines. This technology is applied to the 1.5-liter turbocharged engine designed for power generation within the e-Power hybrid powertrain. Cold spray technology allows for optimized intake port geometry, improving thermal efficiency and cooling performance. The new valve seat is produced by spraying metal powders at supersonic speed onto the cylinder head surface, forming a durable coating without melting the base material.
Why It's Important?
The adoption of cold spray technology in automotive engines represents a significant innovation in powertrain design. By enhancing thermal efficiency and cooling performance, Nissan's new engine could lead to improved fuel efficiency and reduced emissions. This advancement may influence the automotive industry to explore similar technologies, potentially leading to more sustainable vehicle designs. Consumers could benefit from vehicles that offer the smoothness of electric driving with the convenience of traditional engines.
What's Next?
Nissan plans to introduce the new e-Power system in the U.S. and Canada with the next generation Rogue, and in Japan with the all-new Elgrand minivan in FY26. The company will continue to enhance e-Power technology, expanding its availability across various models and markets.
