What's Happening?
Nissan has introduced a groundbreaking application of cold spray technology in its new e-Power dedicated engine, marking a world-first in automotive engineering. This innovative approach involves using cold spray to manufacture valve seats, which are integral to the engine's performance. The technology allows for the creation of a robust and durable coating by spraying metal powders at supersonic speeds onto the aluminum alloy cylinder head surface. This method enhances thermal efficiency and cooling performance, crucial for the engine's operation. The new engine, featuring this technology, is part of Nissan's third-generation e-Power hybrid powertrain, first implemented in the Qashqai compact crossover.
