Perkins Reveals Dual-Certified Twin-Turbo Engine

Perkins New Engine

June 18, 2019 - Perkins introduced the 2806J-E18TTA, a dual-certified engine that helps OEMs comply with both Tier 4 Final and Stage V’s most stringent emission requirements.

This means the model can be installed in products used in the EU and North America without modification.

“Having a dual-certified Stage V/Tier 4 Final engine simplifies OEM machine design as the same engine can be used in the highly-regulated EU and U.S., so managing inventory is easier,” said David Nicoll, global marketing director. “The Perkins 2806J-E18TTA compliments the existing 2806D-E18TTA, which is designed for use in lesser regulated countries and expands on our worldwide engine platform offering.”

The new 2806J-E18TTA uses the same robust mechanical electronic unit injector (MEUI) fuel system found in the 2806D-E18TTA. The series twin turbos help to achieve a powerful 800 hp (597 kW) at 1,800 rpm and produce 2,736 lb.-ft. of class-leading torque. A 755 hp (563 kW) rating is also available.

The engine uses a maintenance-free diesel oxidation catalyst (DOC) aftertreatment to meet the emission standards—the ideal solution for engines in the 750-800 hp (560-600 kW) range. There are no coolant, fuel, or electrical connections, which help simplify installation, and the absence of selective catalytic reduction (SCR) means there is no need for diesel exhaust fluid (DEF)—thus eliminating the DEF tank and reducing total package size and helping to minimize the cost of operation for the life of the machine.

“Today’s OEMs pack more components into less space than ever before and flexible installation options help them do that," Nicoll said. "The design of the 2806J-E18TTA allows OEMs to remotely mount a single can DOC, providing that installation flexibility."

The optional engine-mounted aftertreatment (EMAT) eliminates the need to design and test special brackets since the engine and aftertreatment can arrive as a single unit that is ready to be installed.

For OEMs interested in purchasing the new engine, Perkins will be accepting orders starting June 20. For more information on Stage V, visit www.perkins.com/stagev.
