Nissan has adopted a world-first "cold spray" method for the cylinder head of its new 1.5L e-POWER engine. This innovative technique enhances thermal efficiency and power output. The cold spray process, which sprays metal powder at supersonic speeds, eliminates the need for separate valve seats. This allows for an optimized intake port shape, improving combustion efficiency in the engine. This technology, previously used in aerospace, contributes to the engine's high thermal efficiency of 42% and improved durability.
