Caterpillar announces on-highway engine line for 2007
May 1, 2006 12:00 PM
THE NEW Caterpillar on-highway engine line consists of four models — the C7, C9, C13, and C15 — all equipped with the company's ACERT technology for 2007. These engines will be available to order beginning in fourth quarter 2006.
“The new engine line demonstrates that Caterpillar continues to deliver on the promises made when ACERT Technology was first introduced,” said Greg Gauger, director of Caterpillar on-highway power systems. “Cat engines for 2007 meet the more stringent emissions regulations, while still providing customer value in performance and lower operating costs, with no loss — and in the case of mid-range, a gain — in fuel economy. And, they continue to provide the longer life-to-overhaul engine owners need to operate profitably.”
The mid-range C7 engine provides truck and bus ratings of 190-300 horsepower at 2,200 rpm. This 7.2-liter engine provides 520-860 lb-ft. of torque at 1,440 rpm. It is a versatile engine that fits a variety of medium-duty applications.
The C9 now provides heavy-duty power with increased displacement for expanded horsepower ratings, more torque rating options, and a Cat integral brake for heavy-duty performance in a lightweight package. Ratings for this 9.3-liter engine include 285-350 hp at 2,100 rpm for truck and bus applications. The C9 provides 890-1,350 lb-ft. of torque at 1,400 rpm. Caterpillar also will offer a 1,250 lb-ft C9 rating for truck applications in 2007.
A new Cat common rail fuel system optimizes the performance and fuel economy of the C7 and C9 engines, according to Gauger. “The new fuel system provides greater injection flexibility to help these engines comply with the more stringent 2007 emissions regulations and even increases fuel economy by up to 4% over previous models,” he said.
The new C13 is available in on-highway vocational and heavy-duty line haul configurations for expanded versatility. This 12.5-liter engine delivers 1,150-1,750 lb-ft of torque at 1,200 rpm. It provides vocational truck ratings of 305-370 hp and linehaul truck ratings of 380-470 hp. “The new vocational C13 will provide higher torque, better response, improved driveability, automatic transmission compatibility, and higher compression braking,” Gauger said. “This allows Caterpillar to offer a version of the C13 that exceeds current vocational customer requirements while still meeting emissions regulations at a competitive price.”
The heavy-duty, 15.2-liter C15 provides the highest horsepower and torque rating in the industry, with the 625 hp “King of the Hill.” Truck and bus ratings range from 435-625 hp at 2,100 rpm, with torque ratings from 1,550-1,850 lb-ft and a “King of the Hill” torque rating of 1,850-2,150 lb-ft, both at 1,200 rpm.
