Perkins will Unveil Compact Tier 4 Final Engine at ICUEE | Construction News

Perkins' new 404F-E22TA, a diesel engine that meets U.S. EPA Tier 4 Final emission standards, will make its North American show debut at ICUEE in Louisville, Ky., from  Sept. 29 to Oct. 1.

The compact, four-cylinder model heralds a new era for the 400 Series range. It is the first time that common-rail direct injection and full-authority electronics feature on an engine of this size.

Exhibited in Booth N-3303 by Western U.S. distributor Perkins Pacific, Portland, Ore., the new turbocharged after-cooled 2.2-liter engine is targeted at compact equipment manufacturers, especially for construction applications. It will be produced at a Perkins manufacturing plant in Griffin, Georgia.

While the new model retains many of the features that have made the 400 Series the first choice for many original equipment manufacturers (OEMs) globally, it is the addition of the common rail fuel system and full-authority electronics that will provide a marked increase in performance and allow OEMs greater flexibility in tailoring the engine to specific applications. It also allows OEMs to use a smaller displacement engine in machines that where the norm has traditionally been engines of up to 2.9 liters.

Performance from the 404F-E22TA has been boosted to 67 hp with a maximum torque of 208 Nm (153.4 lb.-ft.) at 1,800 rpm, and a top rated speed of 2,800 rpm. OEMs can also choose a turbocharged non-aftercooled model offering up to 48 hp.

As a result, users will experience better load acceptance, good transient response, and smoother overall operation from machines equipped with this top-of-the-range 400 Series model.

As an added benefit, the better performance comes with lower fuel consumption.  Real-life testing has shown that the new engine uses 7% less fuel than the Tier 4 Interim version. That improvement has been aided by better heat rejection that enables lower fan speeds.

The compact package size and sleek engine architecture, featuring a rear-mounted small diesel oxidation catalyst (DOC), allows OEMs to adopt no-compromise machine designs across many kinds of compact construction equipment.

“The launch of the 404F-E22TA represents a significant evolution for the 400 Series," said Kate Theobald, 400 Series product marketing manager. "For OEMs in the compact machinery market, it offers some compelling advantages, not least of which is the ability to transform how their machines perform and operate.”

Theobald added that engine's flexibility and compactness make it easy to integrate into machines, and that its lower fuel consumption and reduced noise will also be welcome benefits.
