The Perkins 2806C-E18TTAG7 is a 6-cylinder, 18.1-litre twin-turbocharged (series turbocharging), air-to-air charge-cooled diesel engine positioned as the highest power tier of the 2806C generation within the Perkins 2800 Series, built on a proven heavy-duty industrial base for the standby power generation sector. It is designed for OEM genset integration at the 850–938kVA class, serving standby and prime power applications across telecom, data center, industrial, and mining backup power installations. Compared to single-turbo TAG variants in the 2806 series, the twin-turbo TTAG7 delivers the highest rated output in the generation while retaining the common engine core architecture, mechanically operated unit fuel injectors with electronic control, and EU Stage II / EPA Tier 2 emissions compliance.

Build List Identification Guide
The Build List is stamped on the engine nameplate, mounted on the rocker cover or timing case. Locate the dataplate and read the alphanumeric string beginning with JGM or JGMF.
Nameplate fields to record before ordering:
· Build List (e.g. JGMF8094 or JGM8094)
· Engine Serial Number (ESN)
· Rated speed (1800 rpm)
Provide both the Build List and ESN when requesting a quote. This allows us to confirm exact specification match before order commitment.

FAQ
Q1: Where can I find the Build List for my 2806C-E18TTAG7 engine?
The Build List is stamped on the engine data plate and also referenced on the original purchase documentation. Contact your distributor with the ESN if the plate is unreadable.
Q2: What is the difference between TAG and TTAG variants, and does the twin-turbo design affect load acceptance?
TTAG models use a twin-turbocharger (series turbocharging) configuration to reach the highest power tiers in the 2806 range, whereas single-T TAG variants use parallel single-turbo aspiration; the trade-off of the twin-turbo design is comparatively lower step-load acceptance, so genset control panel and load-bank testing should account for this during commissioning.
Q3: How do I confirm genuine Perkins parts versus aftermarket alternatives?
Genuine Perkins parts carry official Perkins part numbers verifiable through MyEngine or your authorized distributor; aftermarket parts may share dimensions but are not warranted for OE compatibility.
Q4: Is the 2806C-E18TTAG7 compatible with OEM genset builds using existing 2806 mounting designs?
Yes, the 2806 series shares a common engine core architecture, allowing shared mounting locations across the family to reduce canopy redesign costs.
Q5: What lubrication specification does the 2806C-E18TTAG7 require?
To be supplemented — pending oil specification confirmation from Perkins TDS/lubricant data sheet.
Q6: What does the ElectropaK configuration include?
ElectropaK configuration includes engine-mounted ECM, wiring harness to ECM, radiator, fuel filtration, air filtration, and automatic stop/alarm sensor readiness as standard equipment.
Q7: How does fuel consumption compare across load points at 1800rpm?
At 1800rpm, specific fuel consumption is approximately 208 g/kWh at 110% load, 210 g/kWh at 100% load, 215 g/kWh at 75% load, and 214 g/kWh at 50% load (Prime rating).
