3D Printed Piston for Heavy-Duty Diesel Engines

3D printing is a rapidly evolving technique for alternative piston manufacturing that offers the ability to realize complex combustion bowl geometry, robust structure and advanced cooling channel geometries while delivering precise tolerance and mass control. IAV has designed, analyzed, optimized and produced 3D printed pistons for heavy-duty diesel engines. The key features include an innovative form of combustion bowl, 300 bar peak cylinder pressure capability and advanced cooling channels in a mass neutral to less capable design. During 2018, these pistons will undergo fired engine testing.
