Specifications per Kirloskar Oil Engines Ltd (Kirloskar Powergen)'s official "25-58.5 kVA CPCB IV+ Compliant" technical specification catalogue (print code 20240610/REV01/A4; footer text says "CPCB IV+25-82.5 kVA", likely a reused template footer -- the cover and spec table both clearly state 25-58.5 kVA, trusted over the footer). Sourced from the open web (kirloskaroilengines.com) as part of a targeted search for the site's remaining zero-model brands. Verified via bore x stroke x cylinder-count vs. stated displacement cross-check (110x125mm x 3-cyl = 3.564L, matches stated 3.57L). Same engine block as 30 kVA (3R1190) but Turbocharged Aftercooled tune vs. Naturally Aspirated. Rated Prime only -- no Standby figure given. This range explicitly names CRDi and a DOC+EGR exhaust aftertreatment combination. Noise (75 dBA) is the document's own stated design ceiling, not a certified per-unit test result. Two weight figures given (Dry, Wet w/o fuel) -- uses Dry per site convention. No fuel-consumption LPH figure stated anywhere -- left null. No warranty or price figure stated.
