The CAT 3126B is a diesel engine manufactured by Caterpillar Inc. Powerfully efficient and built to withstand the toughest duty cycles, the 3126B includes three unique engine components.
First, the torque limiting feature allows the torque to be limited to a selected value (within limits) across the lug curve via a switch input to the electronic control module of the engine.
The second component is the top engine limit (TEL) that limits speed along the engine lug curve that the engine will not exceed. TEL allows for rating flexibility without the need for special ratings or iron.
The third unique component, power trim, allows an OEM to adjust the lug curve vertically (relative to speed) anywhere between -3 and +3 percent. The engine also features the HEUI (Hydraulically actuated Electronically controlled Unit Injector) fuel system and ADEM™ III, an advanced electronic control system. The 3126B meets EPA Tier 2 and EU Stage II emissions
