Fuel-efficient diesel engines meet emission regulations
PowerTech Plus diesel engines meet Tier 3/Stage III A emissions regulations. Choose from 6.8- and 9-liter, 6-cylinder models. Cooled exhaust gas recirculation
PowerTech Plus diesel engines meet Tier 3/Stage III A emissions regulations. Choose from 6.8- and 9-liter, 6-cylinder models. Cooled exhaust gas recirculation (EGR), variable geometry turbocharger, and electronic control unit enhance fuel efficiency. Cooled EGR allows measured amounts of cooled exhaust gas to mix with incoming fresh air, lowering exhaust temperature and reducing oxides of nitrogen (NOx).
