Kenworth has produced informative brochures on the new PACCAR PX-7 and PX-9 engines developed to meet the Environmental Protection Agency (EPA) regulation requiring all model-year 2013 engines be equipped with On-Board Diagnostics (OBD). OBD is designed to monitor the performance of the vehicle's emission system to help detect emission issues, recognize component faults, and ensure optimal performance.
The 6.7-liter PACCAR PX-7 delivers superior performance, minimizes operational costs and maximizes uptime for medium duty customers. The engine has a standard base warranty of 2 years with no mileage limit.
The 8.9-liter PACCAR PX-9 possesses one of the highest power-to-weight ratios in its class with heavy duty features such as replaceable wet liners, roller cam followers, bypass oil filtration and targeted piston-cooling. The engine has a standard base warranty of 2 years or 250,000 miles, whichever comes first.
Both the PACCAR PX-7 and PACCAR PX-9 brochures feature detailed engine horsepower, torque and governed rpm ratings. Charts map horsepower and torque versus engine speed (rpm). A detailed specifications list and maintenance intervals for oil and filter, diesel exhaust filter (DEF) filter and fuel filter are included.
The PACCAR PX-7 engine is available for Kenworth's medium duty conventional and cabover line-up. The engine offers ratings of 200 to 325-hp and up to 750 lb-ft of torque for the Kenworth T170, T270 and T370. For the Kenworth K270 and K370 cabovers, PACCAR PX-7 ratings are 220-hp /520 lb-ft, 240-hp/560 lb-ft and 250-hp/660 lb-ft.
