High-Heat Turbo EGR Sleeve

This heat shield is integrated into the air-intake manifold inlet for high air-temperature applications like diesels.  In this area of the manifold, hot exhaust gas (EGR) is mixed with ambient-temp (fresh) air without failure of adjacent components.  The plastic heat shield offers several improvements vs. previous systems including greater design flexibility (molded-in vs. machined geometry); improved air/EGR mixing (thanks to molded features, which increase turbulence); 50% weight savings; enhanced component durability; and inherent corrosion resistance. A special heat-stabilized grade of 35% GR PA 6/6 is injection molded for the sleeve, replacing roll-formed aluminum and readily withstanding the continuous-service temperature of 220C and peak temperature of 240C. The application was cost neutral but reduced mass by 50%.
