Perkins has launched its new 404F-E22TA, an 67-hp diesel engine that meets U.S. EPA Tier 4 Final/EU Stage IIIB emission standards.
This is the first engine of this size to have common rail direct injection and full authority electronics.
Perkins says that the new turbocharged, aftercooled 2.2-liter model should be of particular interest to compact equipment manufacturers, especially for construction applications.
While the new model retains many of the features that have made the 400 Series popular with original equipment manufacturers (OEMs) globally, adding the common rail fuel system and full authority electronics will provide a tangible and 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 where traditionally engines up to 2.9 liters may have been the norm.
Performance from the 404F-E22TA has been boosted to 67 hp (50 kW) with a maximum torque of 153.4 lb. ft. (208 Nm) at 1,800 rpm, while maximum rated speed is 2,800 rpm. A turbocharged, non-aftercooled model, offers up to 48 hp (36 kW).
As a result, operators will experience better load acceptance, good transient response, and overall smoother operation from machines equipped with this top-of-the-range 400 Series model, says Perkins.
Real-life testing has shown the newly introduced Tier 4 Final engine uses 7% less fuel than its Tier 4 Interim/Stage IIIA version. The improvement has been helped by better heat rejection, which enables lower fan speeds.
Perkins says its goal for all of its engines is making the transition to Tier 4 Final/Stage IIIB as seamless as possible in order to help OEMs avoid costly machine redesigning.
The compact package size, sleek engine architecture, and small rear-mounted diesel oxidation catalyst (DOC), let OEMs to adopt no-compromise machine designs.
“The launch of the 404F-E22TA represents a significant evolution for the 400 Series. 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,” explained David Kidder, 400 Series product 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 and welcomed. Performance aside, we have also managed to improve SFC, lower noise, and retain the compact dimensions that are so necessary for this sector,” he added.
