Kirloskar – other nonroad diesel engines: the collective page of two- to four-cylinder ranges outside the named models, model years running to 2026, 12 to 115 kW, consistently Tier 4 Final
Kirloskar Oil Engines of Pune, India, carries a second certification series in the EPA register alongside Kirloskar Americas for the same two- to four-cylinder engines. This page gathers the engines the register could not assign to a named range, from the two-cylinder 2R550NA1 and 3R550NA1 to the four-cylinder 4R810 and 4K1080 range.

The register lists here 6 versions with 12 to 115 kW rated output, consistently at 1,800 rpm, from two- to four-cylinders with 86 to 105 mm bore and 94 to 125 mm stroke, torques from 61.2 to 608 Nm. Three of the six engines carry a fixed-geometry turbocharger. Model years start between 2018 and 2022 and, on all six versions, run through to 2026; all six consistently reach the Tier 4 (Final or Phase-in) emission stage.
Kirloskar engines of this size chiefly drive compact construction machinery, generator sets and farm pumps in India and for export; model years running to 2026 show the range stays in the programme for the longer term.
As nonroad engines, units of this size fall under the emission stages for mobile machinery rather than road rules for vehicles; the three naturally aspirated variants offer a simpler, if less powerful per litre, alternative to the three turbocharged engines within the same range.
When buying used, operating hours and the condition of the injection pump and nozzles matter, on the turbocharged four-cylinders the tightness of the charge-air system, radiator and oil level; spares run through Kirloskar's distribution.
