6068HFC93 6.8L ENGINE 129 KW (173 HP)

    PowerTech PVX 6.8L engines feature a variable geometry turbocharger (VGT) that varies exhaust pressure based on load and speed to ensure proper cooled exhaust gas recirculation (EGR) flow. EGR cools and mixes measured amounts of cooled exhaust gas with incoming fresh air to lower peak combustion temperatures, thereby reducing NOx. The combination of the cooled EGR and VGT provide low-speed torque, quicker transient response, higher-peak torque, and world-class fuel economy. These engines also utilize a catalyzed exhaust filter that contains a diesel oxidation catalyst (DOC) and a diesel particulate filter (DPF). The DOC reacts with exhaust gases to reduce carbon monoxide, hydrocarbons, and some particulate matter (PM). The downstream DPF traps and holds the remaining PM.
