LOADING HAULING Tier 4i-Compliant Terex Backhoe Loader Available Powered by an electronic, Tier 4 in‐ terim Perkins 1204E‐E44TA engine and an optional 4‐speed servo power synchro transmission with automatic shifting, the 94‐hp Terex TLB840 backhoe loader is now available in North America. Engineered to excel in digging, reaching, lifting and loading applications, North American cus‐ tomers will notice the TLB840 boasts high torque, powerful performance, as well as strong climbing and digging capabilities. The Tier 4i‐compliant engine on the TLB840 is designed with EGR (Ex‐ haust Gas Recirculation) technology, which is well‐suited for lower horse‐ power engines operating in high‐duty applications. EGR engines incorporate diesel oxidation catalyst (DOC) sys‐ tems and sometimes diesel particulate filters (DPF) to reduce nitrogen oxide (NOx) and particulate matter exhaust emissions. reduced," said Jon Beckley, Terex global product manager for backhoe loaders. "This backhoe loader does not require Diesel Exhaust Fluid, also known as AdBlue, or forced regenera‐ tion. Also, we have had a long heritage of strong global support with Perkins." Terex, www.terex.com/construction The new Perkins Stage III B/Tier 4i EGR engines, like the one in the Terex TLB840, include a DPF and allow auto‐ idle to be incorporated in machine. "The Perkins DPF has a 10,000‐hour service life, so maintenance needs are Deere Expands Final Tier 4/Stage IV Engine John Deere Power Systems introduced the PowerTechTM PWL 4.5L engine, which will meet Final Tier 4/Stage IV emissions regulations without a diesel particulate filter (DPF). The 63 kW to 104 kW (85 hp to 140 hp) engine was announced at bauma 2013 in Munich, and complements the John Deere lineup of Final Tier 4/Stage IV off‐ highway diesel engines rated 36 kW to 448 kW (48 hp to 600 hp) announced earlier. The PowerTech PWL 4.5L engine re‐ duces cost and improves engine pack‐ aging by eliminating the DPF while still meeting customer performance expectations for applications in the 56 kW to 104 kW (75 hp to 140 hp) power segment. The engine is equipped with an Inte‐ grated Emissions Control system con‐ sisting of selective catalytic reduction (SCR), a diesel oxidation catalyst (DOC) and cooled exhaust gas recircu‐ lation (EGR) technology. Elimination of the DPF was enabled through com‐ bustion system optimization and im‐ provements in SCR system conversion efficiency. "We believe the elimination of the DPF will serve OEMs and end users well in the very competitive 56 kW to 104 kW 22 ROCKproducts • JULY 2013 (75 hp to 140 hp) segment, balancing packaging and product cost considera‐ tions with performance and operating cost requirements," said John Piasecki, director of marketing, sales and cus‐ tomer support for John Deere Power Systems. "We expect emissions tech‐ nologies will continue to evolve and improve, and we'll adopt those changes when available to improve the customer experience." The introduction of the PowerTech PWL 4.5L engine represents the third Integrated Emissions Control system configuration John Deere will offer for Final Tier 4/Stage IV. For the 36 kW to 55 kW (48 hp to 74 hp) power range, John Deere will offer models using a DOC/DPF without cooled EGR or SCR. The PowerTech PWL 4.5L in the 56 kW to 104 kW (75 hp to 140 hp) power range will be equipped with an Integrated Emissions Control system configured with SCR, a DOC and cooled EGR. Engine models above 104 kW (140 hp) will feature an Integrated Emissions Control system consisting of cooled EGR, a DOC/DPF and SCR. All John Deere Integrated Emissions Control systems are exclu‐ sively designed to meet the specific de‐ mands of off‐highway applications in the given power categories. "At John Deere, we tailor our Inte‐ grated Emissions Control system con‐ figurations to meet customer needs and Final Tier 4/Stage IV emissions regulations," Piasecki said. "We're con‐ fident that all of our solutions will de‐ liver industry leading performance and value while also meeting required long term emissions compliance." John Deere also attained an industry leading fuel‐economy position with its Tier 3/Stage III A and Interim Tier 4/Stage III B engines, the company said. With the move to SCR technology for Final Tier 4/Stage IV engines, total fluid economy becomes important, and John Deere is confident that its total fluid operating costs will con‐ tinue that industry leadership.
