Kenworth releases PACCAR engine brochures

Updated Dec 17, 2012

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 engine brochures are available from your Kenworth dealer and are also available for electronic download at
