The International DT466 engine is a 7.6-liter truck engine used in school buses, farm equipment, dump trucks and construction equipment. It also is utilized in the International CXT, a pickup truck built on the International 20-ton hauler platform. Over one million DT466 engines have been produced.

Engine Design

The DT466 is a turbocharged diesel. It is, according to Brattain, "the only high volume mid-range diesel engine with replaceable wet sleeve architecture." In the wet sleeve design, the cylinder wall thickness is uniform and the cylinder is surrounded completely with coolant.

The DT466 utilizes six bolts per cylinder for head clamping. The purpose of the six-bolt design is to evenly distribute clamping force and improve the life span of the head gasket. Additionally, the DT466 design includes valve rotators and an oil cooler thermostat.

The engine is designed to be overhauled while remaining in the vehicle, lowering overhaul costs.

The engine weight is 1,480 pounds.

Power Ratings

There are six versions of the International DT466 engine as of 2010. The 210-horsepower engine produces peak horsepower at 2,300 rpm and 520 pound-feet of torque at 1,400 rpm.

The 220-horsepower engine produces 540 pound-feet of torque; the 225-horsepower version produces 560 pound-feet of torque; one 245-horsepower version produces 620 pound-feet of torque and the higher-end 245-horsepower version produces 660 pound-feet of torque. The highest powered DT466 engine produces 260 horsepower and 800 pound-feet of torque. All horsepower peaks listed are at 2,300 rpm and torque peaks at 1,400 rpm.

The International DT466 delivers 220 horsepower and 540 pound-feet of torque in the 2004 CXT pickup.

Life Cycle

According to Brattain, International represents that the B10 life of the engine, or the point where 90% of DT466 engines are still running, is 300,000 miles. The B50 life is 450,000 miles under normal operating conditions.
