Source & notes ›
Specifications per Tata Motors' official "497" engine-family genset brochure (Genset Specifications + Engine Specifications 497 tables). Verified via bore x stroke x cylinder-count vs. stated displacement cross-check (97x127mm x 4-cyl = 3754cc vs. stated 3784cc, within ~0.8% rounding). Both the 70 kVA and 82.5 kVA ratings in this brochure share the identical "497" engine block (76 kW gross rated power at the flywheel) -- the genset-level Prime kWe (56 and 66 respectively) follows standard kVA x 0.8 power-factor math, not a second engine tune; recorded as the same engine_model text for both rows deliberately, not a duplication error. Document explicitly and repeatedly states CPCB IV+ (cover badge, "All Tata Motors CPCBIV+ Gensets have CRDI engines", acoustic-enclosure page's "meet stringent CPCB IV+ norms of 75 dBA @1mtr"). noise_db (75) is that same stated ceiling ("<75 dBA"), not a certified per-unit test result. Canopy "Width (mm)" is genuinely left blank in the source table (not a extraction gap on this site's end -- confirmed by re-rendering the page at 300dpi) -- left null rather than assumed. No fuel-tank-capacity or fuel-consumption LPH figure is stated anywhere in this document -- both left null. No warranty or price figures stated. This brochure's "Summary of New Features" page also names two other Tata Motors engine families outside this document's scope, "4SP" (42->55 kW Prime upgrade) and "697" (115->118 kW Prime upgrade) -- not processed here, no spec table for either is included in this PDF. No clean studio product photo was available (the brochure's only genset photos are nighttime/lifestyle composite scenes, e.g. a hotel pool backdrop) -- image_url left null rather than force a bad crop.
