The Rehlko KDI‑TCR 2504E5/26 is a KDI-series 4-cylinder industrial diesel engine configured for EU Stage V non-road applications. It’s intended for modern off-highway machinery and packaged equipment where you need a compact installation footprint, robust performance for demanding duty cycles, and an engine platform that supports current emissions requirements.

The “2504” platform identifies the 4-cylinder architecture used across the KDI range. The “E5/26” designation is the key identifier for matching the correct Stage V build specification and supply package — particularly important for like-for-like replacement and repower projects, where the exact variant determines the correct emissions configuration, calibration and installation requirements.

For OEM builds and replacements, the KDI 2504 platform is commonly selected where service access and long-term maintainability are priorities alongside compliance.
