About the Rehlko KDI-TCF 2504U4/26
The Rehlko KDI‑TCF 2504U4/26 is a KDI-series 4-cylinder industrial diesel engine configured for EU Stage V non-road applications. It’s aimed at OEMs and operators who need a modern diesel platform that supports emissions compliance while still fitting into compact machinery envelopes and packaged power units.
The “2504” platform identifies the 4-cylinder architecture used across a broad range of industrial builds. The “U4/26” designation is the key identifier for matching the correct Stage V configuration and supply package — important for both new equipment integration and like-for-like replacement, where the exact variant determines the correct emissions hardware, calibration and installation requirements.
In practical terms, the KDI 2504 family is commonly selected for high-utilisation industrial duty where reliability and serviceability are priorities. If you share your application details (duty cycle, installation constraints, and any existing engine plate info), we can confirm the right configuration and ancillaries and quote accordingly.
Every engine we supply is set up for its job before it leaves Teignmouth, and backed by the parts and people to keep it running.
