Perkins 2806A-E18TAG3 Diesel Engine for 600-750kVA Generator Sets

The Perkins 2806A-E18TAG3 is a 6-cylinder, 18.1-litre parallel-turbocharged diesel engine built on Perkins' heavy-duty industrial core for the power generation sector. It powers prime and standby generator sets across a 600–750kVA output range at 1500/1800rpm, serving fuel-optimised (non-emissions-regulated) export markets. The dual-turbo (parallel turbocharged, air-to-air chargecooled) configuration gives this 2806A variant improved power density and high-altitude performance relative to single-turbo 2800 Series builds.

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 JGD or JGDF.

Nameplate fields to record before ordering:
· Build List (e.g. JGDF5006 or JGD5006)
· Engine Serial Number (ESN)
· Rated speed (1500 or 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

1. What generator set uses the Perkins 2806A-E18TAG3 engine?

The 2806A-E18TAG3 is factory-fitted in FG Wilson P750-1 and P750-3 generator sets (681.3–750kVA), and is used by several other genset OEMs in the same power range. Always confirm the Build List and ESN, as different OEMs may pair the same engine with different alternators and ratings.

2. What is the difference between the 2806A-E18TAG3 and other 2800 Series engines (e.g. 2806C)?

The "A" prefix denotes a Fuel Optimised, non-emissions-regulated build, while "C" denotes Tier 2/EU Stage II emissions compliance; the TAG3 suffix indicates power output level and applies across compatible prefixes. Core engine design is shared across the 2800 Series, but ECM calibration, fuel injection parameters, and possibly turbo/aftertreatment hardware differ by variant — verify part compatibility via Build List and ESN before ordering.

3. What does "Fuel Optimised" mean, and is this engine emissions compliant?

"Fuel Optimised" indicates a non-emissions-regulated build designed for markets without mandatory exhaust emissions certification, tuned instead for fuel economy. It has no exhaust aftertreatment system (N/A) and is not intended for markets requiring EU Stage or US EPA Tier compliance.

4. What is the Prime and Standby kVA output of the 2806A-E18TAG3?

At 1500rpm, it delivers 600kVA Prime / 650kVA Standby. At 1800rpm, it delivers 681kVA Prime / 750kVA Standby.

5. What is the fuel consumption of the 2806A-E18TAG3?

At 1500rpm Prime, consumption ranges from approximately 197–204 g/kWh across 50–110% load. At 1800rpm Prime, it ranges from approximately 202–210 g/kWh.

6. What information do I need to order the correct replacement parts?

Provide the Build List (e.g. JGDF5006) and ESN, since part numbers for components such as pistons, injectors, and bearings are Build-List-specific. Ordering by engine model name alone risks receiving an incompatible part.

7. Is a remanufactured (REMAN) 2806A-E18TAG3 a reliable alternative to a new engine?

A genuine REMAN engine rebuilt to Perkins OE specification can offer equivalent performance and warranty coverage at a lower cost than a new unit, and is a recognized alternative to a full overhaul. Confirm the REMAN source is Perkins-authorized and that the Build List matches your original configuration.

8. Why do different generator manufacturers list slightly different kVA ratings for the same engine?

The same base engine can be paired with alternators of different efficiency and design by different genset OEMs, producing slightly different published kVA figures even at the same engine power output. Always reference the generator OEM's official data sheet alongside the engine's Technical Specs for the exact configuration you are quoting.
