Automobile Engines with Highly Complex Intake, Exhaust, and Cooling Systems
  • Achieve performance requirements

Automobile engines must provide ever-higher performance while still meeting numerous regulations that grow stricter nearly every year. This need has led to increasingly more complex intake, exhaust, and cooling system layouts and designs. Employing core production technologies delivering high quality, strength, and good core fitment, Yamaha has established techniques for single-piece exhaust manifold assembly and complex two-stage double water jackets. These technologies contribute to the mass production of cylinder heads for high-performance automobile engines.
