Winnipeg, Manitoba (October 30, 2008) -
The QSC 8.3-liter engine from Cummins Inc. (NYSE: CMI) will power the Versatile 250-hp and 280-hp tractor launched today by Buhler Versatile Inc. (TSX: BUI). The QSC engine joins the larger QSM 11-liter and QSX 15-liter engines as part of the Cummins power lineup for the Versatile tractor range meeting U.S. EPA Tier 3 emissions standards and equivalent Canadian regulations.
The six-cylinder, 24-valve QSC offers the premium performance benefit of a Cummins High Pressure Common Rail fuel system that enables cleaner combustion and a faster engine response to deliver deep reserves of torque. Peak torque for the 250-hp rated Versatile tractor is 830 lb-ft (1125 N•m) at 1500 rpm, while the 280-hp rated Versatile tractor provides 1000 lb-ft (1356 N•m) at 1500 rpm. The new tractor takes full advantage of the available torque with a rapid 50 percent torque rise from the 280-hp rated engine and a 39 percent torque rise from the 250-hp rating.
With a very high torque rise, the engine returns to peak torque far more rapidly as rpm speed falls from 2200-rpm rated power due to more difficult working conditions. The tractor maintains a constant drawbar pull even with changing engine load factors. “Cummins QSM- and QSX-powered Versatile tractors have established an enviable reputation in high-productivity farming, and customers of the new Versatile 250 and 280 tractor will be equally impressed with how well the QSC engine performs under the toughest conditions,” said Ric Kleine, Vice President of Cummins Off-Highway Business.
“The QSC offers an exceptionally high torque rise and a power boost feature which both make an important contribution to how well the tractor performs out in the field. Power and torque delivery is faster, quieter and smoother on the new Versatile tractor due to the precision fueling capability of the High Pressure Common Rail system. The tractor is ready to establish new performance standards in its power class,” added Kleine.
With 250-hp (187 kW) and 280-hp (209 kW) rated power at 2200rpm, the QSC is ideally power-matched to the new Versatile tractor to optimize fuel efficiency across all operating conditions. Peak power for the 250-hp rated Versatile is 265 hp (198 kW) and 300 hp (224 kW) for the 280-hp rated Versatile. This additional peak power above rated power arrives at a lower 1900 to 2000 rpm to help pull the tractor though tough spots without the need for downshifting.
The QSC integrates seamlessly with electronic systems on the Versatile tractor and is fully synchronized with the powershift transmission to provide smooth shifting control and programmable features to precisely match work requirements.
“Our application engineers worked closely with the Versatile design team to tailor a specific engine calibration that is optimized for the most fuel-efficient operation across all farm working conditions,” commented Silvio Novaes, Cummins Account Executive, Agricultural Market.
“The Versatile 250 and 280 are highly impressive machines, and the QSC engine will fully contribute to realizing the highest productivity and lowest cost of operation for this class of tractor. The Cummins support team is extremely delighted with this opportunity to power the new line of Versatile tractors with the QSC engine, which now extends Cummins power all the way from 250 hp to 535 hp (399 kW) for the Versatile range.
“This represents a significant milestone in the agricultural market for Cummins and we are honored to be the engine supplier for Versatile tractors, which have such a long and distinguished history in the farming industry,” added Novaes.
HPCR Power Capability
The High Pressure Common Rail (HPCR) fuel system on the QSC was specifically developed and scaled by Cummins to the engine platform size and power output. The system enables multiple injection events with very high fuel injection pressure across all engine rpm speeds, resulting in cleaner combustion and improved engine response. Precision control of fuel injection also enables improved cold-weather starting and idle control for the Versatile tractor. Engine noise and vibration are significantly reduced due to more balanced fueling across the cylinders. Visible smoke is virtually eliminated across most engine load conditions.
The HPCR fuel pump and injectors are built farm tough with superior durability and reliability with no scheduled maintenance intervention required. Optimal fuel efficiency is continuously achieved by full-authority electronic control of the system. The HPCR fuel system is compatible with B20 biodiesel blends conforming to industry-approved standards.
The QSC-powered tractor shares the same ease of servicing as offered by the QSM- and QSX-powered tractors, which is a particular advantage of the Versatile range for operators. Electronic commonality with a plug-in connection within the Versatile cab allows engine data downloads for rapid service diagnostics and engine performance tracking.
