Specifications per Kirloskar Oil Engines Ltd (Kirloskar Powergen)'s official "200-625 kVA HD Series CPCB IV+ Compliant" technical specification catalogue (print code 20240610/REV01/A4). Sourced from the open web (kirloskaroilengines.com) as part of a targeted search for the site's remaining zero-model brands. GENUINELY DIFFERENT physical product from the existing "320-kva" Kirloskar row (6SL90ETA, 6-cyl, 8.86L, 279.5kW) -- this HD variant uses an 8-cylinder DV8ETA block (130x150mm, 15.92L, 294.2kW), a heavier-duty engine providing extra margin at the same 320 kVA nameplate; disambiguated with a -hd slug suffix, explicitly labeled "KG4-320WS (HD)" in the source (unlike the 200 kVA HD row's ambiguous model code). Verified via bore x stroke x cylinder-count vs. stated displacement cross-check (130x150mm x 8-cyl = 15.928L, matches stated 15.92L). Also shares its exact engine block (bore/stroke/displacement/cylinder count) with the site's existing "400-kva" SL-range row (DV8ETA 4G2) -- this is generation suffix 4G1, a different (lower) tune at 294.2kW. Rated Prime only -- no Standby figure given. DOC+SCR aftertreatment with dual 45L DEF/AdBlue tanks (90L total, ISO 22241). Noise (75 dBA) is the document's own stated design ceiling. Two weight figures given (Dry, Wet w/o fuel) -- uses Dry. No fuel-consumption LPH or warranty/price figure stated.
