Perkins 2806A-E18TTAG5 Diesel Engine for 770–888kVA Generator Sets

The Perkins 2806A-E18TTAG5 is a 6-cylinder, 18.1-litre in-line diesel engine built on the Perkins 2800 Series industrial core, positioned for fuel-optimised power generation markets without exhaust aftertreatment requirements. It uses parallel dual turbocharging with air-to-air charge cooling to deliver a high power density suited to prime and standby generator sets from 770 to 888 kVA. As part of the 2806A dual-turbocharged product line, it shares core mechanical architecture with other 2806A variants, offering operators a durable, high-altitude-capable platform with mechanically actuated, electronically controlled unit fuel injection for lower fuel consumption across load ranges.
