The Rehlko KDI‑TCV 3404U4/22 is a heavy-duty configuration within Rehlko’s KDI 3404 family, rated at 100 kW (134 hp) @ 2200 rpm with a strong 500 Nm @ 1400 rpm torque peak. That power-and-torque profile is well suited to equipment that spends most of its time working under load in the mid-range — where pulling power, controllable output, and consistent performance matter more than high engine speed.

This variant is documented for EU Stage IV / US Tier 4 Final compliance and uses Rehlko’s U4 emissions management package (EGR + DOC + SCR). For OEMs, the benefit is a clearly defined engine configuration with a known emissions architecture, helping engineering and procurement teams specify the correct installation package. For operators and service teams, the advantage is a well-supported engine family where accurate variant identification keeps parts and maintenance aligned over the engine’s lifecycle.

Because Stage IV/Tier 4 Final engines depend on correct aftertreatment packaging, it’s important to confirm cooling capacity, exhaust routing, aftertreatment layout, mounting points, and electrical interfaces.
