PowerTech PSX 9.0L engines feature series turbochargers that deliver more boost pressure than single turbocharging configurations which results in higher power density, improved low-speed torque, and improved high altitude operation. These high-performing engines use cooled exhaust gas recirculation (EGR). This technology cools and mixes measured amounts of cooled exhaust gas with incoming fresh air to lower peak combustion temperatures, thereby reducing NOx. 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.
