Kirloskar Americas – other nonroad diesel engines: the collective page of two- to four-cylinder ranges outside the named models, from Pune, 12 to 115 kW at 1,800 rpm, Tier 4 Final and Tier 2
Kirloskar Oil Engines, headquartered in Pune, India, is one of the large Indian makers of small and mid-size diesel engines for farm machinery, pumps and generator sets; under the Kirloskar Americas designation the EPA register carries the versions certified for the North American market. 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. Three of the six engines carry a fixed-geometry turbocharger, and maximum torque ranges from 61.2 to 608 Nm. Five versions reach the Tier 4 (Final or Phase-in) emission stage, one older version is certified to Tier 2 and approved for both sales areas, federal states and California.
Kirloskar engines of this size chiefly drive compact construction machinery, generator sets and farm pumps in North America, positioning themselves as an affordable alternative to established brands such as Kubota or Yanmar in the lower and mid power segment.
When buying used, operating hours and the condition of the injection pump and nozzles matter, on the turbocharged four-cylinders also the tightness of the charge-air system, radiator and oil level, and on the older Tier 2 version a realistic assessment of remaining service life; spares run through Kirloskar's North American distribution.
