Kenworth offers Cummins ISL Engine for Vocational, Pickup and Delivery Duty

KIRKLAND, Wash. -- The enhanced Cummins ISL engine is now available for order on Kenworth trucks.


KIRKLAND, Wash. — The enhanced Cummins ISL engine is now available for order on Kenworth trucks.

Kenworth Truck Company is offering the 8.9-liter, high-performance engine in ratings of 310 to 350 horsepower and 1,050 to 1,250 foot-pounds of torque.

“The Cummins ISL is an excellent engine that is expected to be popular in Kenworth’s short hood T800 and W900S models for vocational and pick-up and delivery applications,” said Steve Gilligan, Kenworth’s general marketing manager. “With a 500-pound weight savings over competitive engines, it’s also a great engine for companies that gross out in weight.”

“Kenworth customers will be impressed with the improved performance and reliability of the enhanced Cummins ISL engine,” said Tom Kieffer, Cummins executive director for marketing, who noted that the engine has accumulated
over three million miles of field-testing.

According to Kieffer, the new Cummins ISL is up to 37 per cent quieter than the previous ISL engine. The quieter operation is due to pilot fuel injection and a revised gear cover.

The Cummins ISL engine also offers the option of the C-Brake designed specifically for the ISL by engine brake manufacturer Jacobs. The product increases stopping power with up to 330 braking horsepower, while reducing wear on service brakes, according to Cummins.

Kenworth owners driving mixers and dump trucks also will be able to benefit from the availability of the ISL’s rear engine power takeoff, say officials. “This is a
great feature for vocational customers or anyone who needs their engine to do double duty,” Gilligan said.

Performance and reliability have been enhanced through the use of a new High Pressure Common Rail fuel system with electronically controlled injectors. High injection fuel pressures are maintained regardless of engine speed for
optimum performance across the entire rpm range.

The ISL engine offers the patented and proven Cummins Variable Geometry Turbocharger. Because it has only one moving part in the hot exhaust stream, the VG Turbo provides reliability and durability. The VG Turbo constantly adjusts airflow based on engine load, altitude and temperature to deliver improved performance and transient response.

Designed with 24-valve centered fuel injection, the ISL offers optimum combustion. The result is improved performance, increased efficiency and less noise, with reduced emissions.

“With all these features, the Cummins ISL delivers great value and outstanding performance for Kenworth customers,” Gilligan concluded.

Cummins Inc. designs, manufactures, distributes and services engines and related technologies, including fuel systems, controls, air handling, filtration, emissions solutions and electrical power generation systems.

Headquartered in Columbus, Ind., Cummins serves its customers through more than 500 company-owned and independent distributor locations in 131 countries and territories.

Kenworth Truck Company, a division of PACCAR Inc, is a manufacturer of heavy and medium duty trucks. Kenworth’s Internet home page is at www.kenworth.com.
