The DT466 is a turbocharged diesel. It is, according to Brattain, “the only high-volume mid-range diesel engine with replaceable wet-jacket architecture.” In the wet liner design, the cylinder wall thickness is uniform and the cylinder is completely surrounded by coolant. The DT466 uses six bolts per cylinder to hold the head. The purpose of the six-bolt design is to evenly distribute clamping force and improve cylinder head gasket life. Additionally, the DT466 design includes valve rotators and an oil cooler thermostat. The engine is designed to be serviced while it remains in the vehicle, reducing servicing costs. The engine weight is 1,480 pounds.
