The Rehlko KDI‑TCN 3404E5/22 is part of Rehlko’s KDI 3404 engine family and delivers 55.4 kW (74 hp) @ 2600 rpm from a compact 4‑cylinder turbo common‑rail platform. This variant is specified for EU Stage V, making it a practical choice for equipment builders and operators who need a modern diesel engine that aligns with current emissions requirements without stepping up to a larger, heavier engine class.

For OEMs, the KDI 3404 platform balances output with integration practicality — a compact footprint, clear variant identification, and a well-supported engine family that helps keep engineering, procurement, and service aligned. The 4‑cylinder layout supports smooth operation for steady-duty applications, while turbocharging and common‑rail injection help maintain responsive performance under load.

If you’re replacing an older engine or specifying for a new build, match the exact 3404E5/22 variant and confirm the installation package (cooling capacity, intake/exhaust routing, mounting points, and electrical interfaces). Share your engine plate details and application, and we’ll help confirm the correct match before ordering.
