Engine manufacturer Perkins will showcase its complete lineup of Stage IV/Tier 4 Final engines up to 225 kW (300 hp) at this year’s Bauma show in Munich. The new compact, four-cylinder 854F-E34TA will spearhead the range, comprising engines from the company’s 400 and 1200 Series as well. The new model incorporates specially optimized Selective Catalytic Reduction technology for the first time.
These engines will be packaged separately from the diesel oxidation catalyst module, allowing for greater installation flexibility for OEMs in the engine bay. Space saving is further enhanced through the absence of a diesel particulate filter.
Performance from the 854F-E34TA has been boosted to 90 kW (121 hp), while the 8-percent improvement in specific fuel consumption gained at Stage IIIB/Tier 4 Interim 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.
Also on display, among others, will be the single-turbo 1206F-E70TA, offering up to 151 kW (202 hp) at 2,200 rpm with maximum torque of 870 Nm at 1,400 rpm. In developing the 1200 Series, Perkins sought to minimize the impact of the after-treatment required to meet Stage IV/Tier 4 Final requirements, in particular the reduction in NOx. Perkins achieved this by packaging the DOC/DPF canister and the SCR system into one integrated module, which can be positioned remotely in a machine chassis or on top of the engine.
Other engines on display include the 1204F-E44TA and the 404F-22.
Perkins will be at Hall A4, stand 316.
