Cat® C7 Delivers Boosted Torque for Enhanced Performance

Caterpillar today announced that four engine models"”the C7, C9, C13 and C15"”will be available for recreational vehicles (RVs) in 2007. These Cat® engines, which feature the company's emissions reduction solution ACERT™ Technology for 2007, will provide the power, performance and reliability customers expect from Caterpillar. And, the C7 provides increased torque ratings up to 925 lb-ft for more power than ever before.

"These engines feature an enhanced version of our ACERT Technology for emissions reduction, which has been in use successfully since 2003," said Jeff Headean, sales manager, Caterpillar On-Highway Engines. "All four engines have been proven over millions of miles"”they offer the power, durability and resale value RV owners need."

In addition to the torque increase in the C7, the C7 and C9 may deliver up to 4 percent improved fuel economy compared to previous models. Caterpillar engines will be available in numerous motor home manufacturers' models in 2007, including Monaco, Country Coach, Spartan, Workhorse and Newell, and several others that are still under discussion.

The 7.2-liter C7 engine will be available in three ratings: 300 horsepower with 860 lb-ft of torque, 330 horsepower with 860 lb-ft of torque, and a new, increased torque rating for enhanced performance, 350 horsepower with 925 lb-ft of torque. This engine will be available the spring of 2007. The 9.3-liter C9 engine also will be available in three ratings: 400 horsepower with 1,250 lb-ft of torque, 425 horsepower with 1,250 lb-ft of torque, and 425 horsepower with 1,350 lb-ft of torque. This engine also will feature the Caterpillar® engine brake for extra braking power.

The 12.5-liter C13 engine will deliver 525 horsepower with 1,750 lb-ft of torque. The largest Caterpillar® engine and the industry's horsepower leader, the 15.2-liter C15, will be available in three ratings: 600 horsepower with 1,850 lb-ft of torque, 600 horsepower with 2,050 lb-ft of torque, and 625 horsepower with 2,050 lb-ft of torque.

"All of our engines are backed by the support of our dedicated Cat RV Center network, which features more than 100 locations spread out across North America," Headean said.

ACERT Technology for 2007

The ACERT Technology employed by the new Caterpillar engine line for 2007 remains a systems solution, refined to meet the more stringent 2007 Environmental Protection Agency (EPA) emissions regulations. Two major enhancements"”a refined combustion process called Clean Gas Induction (CGI) and a self-regenerating Diesel Particulate Filter (DPF)"”ensure that Cat engines meet the 2007 emissions regulations without sacrificing the reliability, durability and fuel economy advantage Caterpillar engines always have delivered, according to Headean.

Clean Gas Induction (CGI) is an exclusive ACERT process that reduces emissions by drawing off a small amount of non-combustible gas after it has been cleaned by the engine's aftertreatment system. The gas is then cooled, blended with more incoming cool, clean air and returned to the combustion chamber. The difference between CGI and the technology employed by competitive engines"”cooled exhaust gas recirculation (EGR)"”is that cooled-EGR sends unfiltered exhaust back through the system, which exposes engine components to high levels of soot that contribute to shortened engine life.
"The use of cooler, cleaner air helps preserve fuel economy and should result in longer life-to-overhaul with a higher resale value," Headean said.

The 2007 Cat engines will feature a new, Caterpillar manufactured diesel particulate filter (DPF) to further reduce particulate matter. DPFs accumulate particulate matter (soot) that must be oxidized away to clean the filter. This exclusive Cat design employs active regeneration, which means that when the temperature of the engine isn't high enough to oxidize (burn) the soot that collects in the DPF, the exhaust gas is heated by auxiliary means. When the engine electronic control monitor detects soot buildup, the Cat Regeneration System (CRS) automatically uses only the precise amount of fuel necessary to heat and oxidize the soot. The Caterpillar design will automatically regenerate under all conditions without any driver involvement. When cleaning is eventually required"”as it is with all DPFs"”the Cat DPF may be cleaned in a couple of hours without removing it from the vehicle, which means less downtime.
"ACERT Technology for 2007 is simply an enhanced version of the original, which has been proven over millions of miles," Headean said. "In terms of performance, durability, engine life and resale value, Caterpillar will continue to provide the value our RV customers have come to expect."
