Perkins Engines Co. displayed its new 404F-E22TA, a Tier 4 final engine, at the ICUEE show, Sept. 29-Oct. 1. It is the first time common rail direct injection and full authority electronics are featured on an engine of this size, Perkins said.
The engine was exhibited by U.S. distributor Perkins Pacific, based in Portland, Ore., and will be produced at a Perkins manufacturing plant in Griffin, Ga.
The addition of the common rail fuel system and full authority electronics that will provide a tangible increase in performance and allow OEMs greater flexibility in tailoring the engine to specific applications, Perkins said. It allows OEMs to use a smaller displacement engine in machines where traditionally engines up to 2.9 liters may have been the norm.
Performance from the 404F-E22TA has been boosted to 67 hp with a maximum torque of 208 Nm at 1800 rpm, while rated speed is up to 2800 rpm. OEMs also have the option of a turbocharged non-aftercooled model, offering up to 48 hp.
Also real lift testing has shown a 7-percent improvement in specific fuel consumption previously gained at Tier 4 interim, aided by better heat rejection enabling lower fan speeds.
“The launch of the 404F-322TA represents a significant evolution for the 400 Series,” said Kate Theobald, 400 Series product marketing manager. “The sheer flexibility of this engine in terms of machine integration is a real step-change and the benefits for OEM customers will be tangible.”
