LOUISVILLE, KY. Using a new diesel particulate filter (DPF), proprietary DPF regeneration system and a modified version of its ACERT technology, Caterpiller will offer four on-highway engine models in 2007 covering all current power ratings, according to company officials. Speaking at a press conference during the Mid-America Trucking Show, Jim Parker, vp of the power systems marketing division, added that “ACERT with some modifications also gives us a clear line of sight to meeting 2010 emissions levels.”

Medium-duty applications in 2007 will be covered by the C7 and C9, which will get a new common rail fuel system and variable vane turbochargers to help them meet the new emissions requirements.

With displacement unchanged from current models, the 7.2L C7 will be offered in rating ranging from 190 to 300 hp at 2,200 rpm for truck and bus applications. Fire-truck ratings of 300 to 350 hp at 2,400 rpm will also be available. Peak torques will range from 520 to 860 lbs.-ft. at 1,440 rpm.

Displacement for the C9 will be boosted a bit for 2007, growing to 9.3L as well as acquiring a Cat integral engine brake. Ratings will be from 285 to 350 hp at 2,100 rpm for trucks and buses, and 335 to 425 hp for fire trucks. Peak torque ratings will range from 890 to 1,350 lbs.-ft. at 1,400 rpm, and will include for the first time a 1,250 lbs.-ft. rating for trucks.

In heavy-duty trucks, the C13 will continue to cover on-highway applications and replace the C11 in vocational uses. The 12.5L engine will be available in ratings of 380 to 470 hp for on-highway models, 305 to 370 hp for vocational models and 485 to 525 for fire-truck versions, all at 2,100 rpm with peak torques ranging from 1,150 to 1,750 lbs.-ft.

At the top of its engine line, the 2007 C15 will continue offering ratings from 435 to 625 hp for truck applications and 600 to 625 hp for fire trucks, all at 2,100 rpm. Torque rating for the 15.2L engine will range from 1,550 lbs.-ft. all the way up to 2,150 lbs.-ft.

Approximately 100 engines with the 2007 technology have already run up 3 million miles in revenue-hauling field tests for a number of fleets, according to Steve Brown, Caterpillar’s director of on-highway engine marketing. Field test mileage should exceed 12 million miles by Oct., he said at the press conference. Caterpillar says it will begin taking orders for production versions of its 2007 engines in the fourth quarter this year.
