Engine and emissions technology enhancements in Interim Tier 4 engines improve fuel and DEF use efficiency, help reduce operational costs
Duluth, Ga. (April 14, 2011) — Professional producers purchasing interim Tier 4-compliant Massey Ferguson® 8600 Series and Challenger® MT600D Series high-horsepower row crop tractors will experience greater efficiency and lower operating costs beyond those delivered by Tier 3-compliant machines, thanks to engineering advancements featured in these 2011 models. Producers also will have access to increased horsepower as Massey Ferguson introduces the fifth model in the Series, the new MF8690 featuring 290 PTO horsepower. The popular Challenger MT600D Series also will be expanded to five models with the introduction of the MT685D at 290 PTO horsepower.
“As we launch new machines with additional levels of environmental compliance, we’re striving to provide our customers with both engineering advancements and new design features that deliver added value to their operations,” says Mike Alvin, product marketing manager for high-horsepower tractors. “Our 2011 models do just that through refinements to our e3 Selective Catalytic Reduction (SCR) system. These changes allow us to further improve fuel efficiency and improve diesel exhaust fluid use efficiency, meeting interim Tier 4 emissions compliance without compromising engine performance. These improvements also offer the operator some nice savings on operational costs.”
“In addition, we’ve improved operator comfort and convenience through updates to the cab and the external design of these machines,” Alvin adds.
For Massey Ferguson, 2011 model numbers will not change. However, the Challenger Series designations will become MT600D. Each series will continue to offer machines with PTO horsepower ratings of 205, 225, 250 and 275.
Three engineering enhancements combine to provide the improvements in fuel efficiency and utilization of diesel exhaust fluid (DEF) used in the SCR system to meet NOx emission compliance standards. First, pressure within the common-rail fuel injection system was increased nearly 50 percent to more thoroughly atomize fuel, improving diesel use and lowering overall fuel usage. Addition of an industry-exclusive pivoting cooling system also helps improve fuel efficiency by capturing, cooling and directing unburned fuel back into the fuel system.
Finally a new DEF injection system featuring a NOx sensor measures the exhaust before it enters the diesel exhaust catalyst. The system then injects the most appropriate rate of DEF needed to match the engine load and best oxidize the emissions being produced to reach the interim-Tier 4 95 percent NOx reduction requirement. This real-time injection process varies the DEF rate, averaging about 5 percent DEF to diesel, but lowers the overall DEF use as compared to the previous system.
Hydrocarbon particulate matter emission requirements are met through the use of a maintenance-free diesel oxidation catalyst which is designed to be in service for the lifetime of the machine. The only operator-required activity is addition of DEF to the resized tank. These 2011 models feature a 167-gallon diesel tank and a 16-gallon DEF tank for a 2:1 diesel to DEF refill ratio as well as less frequent refueling to keep the machines in the field and working longer.
Cab comfort and operator convenience updates
While the Massey Ferguson 8600 Series and Challenger MT600D Series tractors boast some of the largest, quietest, most ergonomically designed cabs in their class, more conveniently placed controls and a new CAN software customized control keyboard improves operator comfort and efficiency. The keyboard includes controls for the 3-point hitch, depth, cruise speed, hydraulic lock function as well as A and B engine presets.
New right-side integrated cab steps, with adjustable bottom step offer better operator access. New placement and increased capacity of the diesel and DEF tanks make refills easier and less frequent while a more open-style fender option is another change for the 2011 models.
