The Rehlko KDI‑TCR 1903E5/26 sits within Rehlko’s KDI 1903 family and is rated at 42 kW (56 hp) @ 2600 rpm, producing 225 Nm @ 1500 rpm. That torque-at-working-speed profile makes it a strong choice for compact machinery that needs usable pulling power and predictable performance under load, without stepping up to a larger engine class.

This variant is documented with broad emissions coverage — including EU Stage V — and uses Rehlko’s E5 emissions management package (EGR + DOC + DPF) as shown in the quick specifications table. For OEMs, the benefit is a modern turbo common‑rail platform with a clearly defined variant code and a known emissions architecture, helping engineering and procurement teams specify the correct installation package. For operators and service teams, accurate variant identification keeps parts ordering and maintenance aligned across the engine’s lifecycle — particularly important where multiple 1903 variants share similar headline figures.

Before ordering, match the exact engine plate code and confirm the integration details (cooling arrangement, intake/exhaust routing, mounting points, and electrical interfaces). Share your application and current engine code and we’ll help confirm the correct match.
