Perkins Engines presented its new 854F-E34TA Tier 4 Final engine at the Bauma Trade Fair in Munich last week. The new compact, four-cylinder, 3.4-liter model incorporates specially optimized selective catalytic reduction technology for the first time. Packaged separately from the diesel oxidation catalyst module, it can be mounted in either a horizontal or vertical position, giving OEMs of compact machinery greater installation flexibility in the engine bay.

The absence of a diesel particulate filter saves space. The absence of a DPF is enabled by the introduction of a four-valve cylinder head, and increasing the common rail fuel pressure to 1800 bar. Performance has been boosted to 90 kW (121 hp) with a maximum torque of 460 Nm because of its single-stage turbo with smart wastegate. Rated speed is between 2,200 and 2,500 rpm.

The 8-percent improvement in specific fuel consumption previously gained at the Tier 4 interim level has been retained. Heat rejection remains similar to its predecessor, meaning no major changes to the size of the cooling pack, helping to maintain the engine’s compact dimensions and serving to avoid costly machine redesign.

The compact package size of the 854F-E34TA helps manufacturers of telehandlers, skid-steer loaders and compact wheel loaders avoid having to redesign machines.  Service intervals remain at 500 hours while maintenance costs have been reduced with the use of poly-vee belts and hydraulic lash adjustment.

“Moving from one level of emission standards to the next has certainly been a challenge for most construction OEMs, giving the need to accommodate the after-treatment necessary to meet the new standards,” said Dan Clayton, Tier 4 product manager.

The launch of the 854F-E34TA at Bauma 2013 marks the completion of Perkins’ Stage IV/Tier 4 Final engine range, which includes the Perkins 400 and 1200 Series.
