Truckers and fleets can now order the Caterpillar C15 engine in 625- and 600-horsepower ratings in Kenworth's W900L long-nose conventional.
Caterpillar's “King of the Hill” 625-hp C15 provides 2,050 ft-lb of torque at 1,200 rpm and constant torque to 1,500 rpm. Maximum 625 hp is developed at 1,800 rpm with 595 hp at 2,100 rpm. The new product is built on a Cat engine platform with the same bore and stroke as the 550-hp C15. Advances include new pistons and injectors for the higher-flow series turbochargers, and the Caterpillar electronic control module that is four times faster than the previous C15 ECM and has twice the memory.
Caterpillar's new 600-hp rated C15 has 1,850 ft-lb of torque at 1,200 rpm.
Kenworth is also offering an optional Caterpillar compression brake, which is the only compression brake available for these engines. The Cat compression brake provides 600 retarding horsepower. For more details, contact Kenworth, PO Box 1000, Kirkland WA 98083-1000.
