The Cummins ISL engine is now available for order in Peterbilt's low-cab-forward Model 320, Peterbilt Motors Co. has announced.
The Model 320, popular in refuse and municipal applications, is available with the Cummins ISL in ratings of 310 HP with 1,050 lb.-ft. of torque and 330 HP with 1,150 lb.-ft. of torque. The engine comes standard with a Horton Drivemaster fan clutch and a Cummins 18.7-cfm air compressor.
Dan Sobic, Peterbilt assistant gm, said the Cummins ISL is significantly lighter than any other engine in its class, yet provides ample power and reliability.
The Cummins ISL also features a patented high-pressure fuel system that delivers high injection pressures independent of engine speed for enhanced throttle response, fuel economy and emissions reduction, Sobic said.
