Net power is configuration-dependent and separate from gross mechanical output; no electrical genset output inferred. ESP applications only: all printed PRP figures are reference only and not supported prime-duty ratings. Emissions statement as printed: Unregulated; no additional certification inferred. Production status is unknown; discontinued is the user-authorized catalogue classification, not manufacturer-confirmed cessation. No production-end year asserted. Physical specifications added from manufacturer datasheets, 2026-10-21: compression ratio 16.5:1; dry engine weight 9553 kg without radiator and radiator pipes; overall dimensions without radiator (L × W × H) 2859 × 1556 × 2616 mm.
