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.
