The DT466 was originally released in 1984 as the International Harvester DT466. All versions of the DT466 and MaxxForce DT use a cast-iron, wet sleeve-engine block design with the six cylinders arranged in an in-line configuration. First-generation DT466 engines used a mechanical fuel injection pump until 1994, when a hydraulic/electronic unit injector first became available. HEUI injectors are standard on DT466 engines produced from 1996 to 2004, after which the fuel system uses a Generation 2 HEUI unit.
Turbocharging to improve efficiency and power is a standard feature of the DT466 engine, present since its inception. The current-generation MaxxForce DT iteration of the engine uses a dual-sequential turbocharger system first added to the engine in 2010. These dual turbochargers replaced the older single variable-vane unit as part of modifications to the DT466 design to help meet new emissions standards that came into force in 2010.Learn more about Engine
