International refers to its DT466 engine as "The Legend." Businesses and industries employ the machine in numerous medium-use applications, such as moving trucks, box trucks, fire trucks and buses, and in some heavy-duty applications. With features including its dual sequential turbochargers and an engine life of about 550,000 miles, the DT466 provides product strength, durability and longevity. When the engine needs rebuilding, there is less downtime for the work, because the wet-sleeve cylinder design permits the engine to remain in the chassis under most circumstances. The hardened, prefinished cylinder sleeve is wet because the engine's coolant is in contact with the sleeve directly.
From 1984 to 1995, the DT466 engine featured a mechanical injection pump. In 1994, International began building the engine featuring the HEUI injection system. The four-cycle, six-cylinder engine's governed speed is about 2,500 revolutions per minute.Learn more about Engine
