Standing for direct injected, turbocharged, and aftercooled, this acronym describes a high-efficiency diesel engine architecture. The setup sprays fuel directly into the combustion chamber, uses exhaust gases to force extra air into the intake, and cools that compressed air before it enters the cylinders. This combination maximizes power output and fuel efficiency while minimizing harmful emissions in heavy-duty applications.
We're swapping in a Cat 3126 DITA to get better low-end torque for towing heavy equipment.
