PHOTO: ŠISTOCKPHOTO.COM/DODGE FEATURES NEW 3.0L V-6 ECODIESEL The new 3.0L V-6 EcoDiesel is among today's most advanced diesel engines. Its emissions are 60-percent less than those produced by diesel powertrains 25 years ago. The small displacement 3.0L EcoDiesel engine offers V-6 capability with lower CO2 emissions, while the 240-hp turbo-diesel mated to the 8-speed TorqueFlite 8 automatic enhances fuel economy and range. BY MIKE ANTICH T he 2014 Ram 1500 pickup can be equipped with a new, 3.0L EcoDiesel engine mated to the 8-speed TorqueFlite automatic transmission. Te new, 3.0L 24-valve, dual-overhead-cam (DOHC) EcoDiesel is a turbocharged 60-degree V-6. It generates 240 hp at 3,600 rpm and produces 420 lb.-f. of torque at 2,000 rpm. Te EcoDiesel V-6 incorporates Fiat's MultiJet II common-rail fuel-injection system, which features 29,000 psi of line pressure. High-dispersion nozzles and a new servo valve enable fuel-injection events, which occur with greater precision up to eight times per cylinder cycle. Tis ensures efciency via clean, smooth combustion. Te EcoDiesel's 60-degree cylinder-bank angle and 1-2-3-4-5-6 fring order are optimized to manage inertia and fring loads, eliminating the need for a balance shaf. Te engine's aluminum cylinder heads are heat-treated and feature individual bearing 58 AUTOMOTIVE FLEET I DECEMBER 2013 caps that help reduce friction and noise, vibration, and harshness (NVH). Te system also incorporates a new "pre-flter" on the transmission cross-rail and an engine fuel flter. Te result is enhanced prevention of injector corrosion, an enabler of long-term durability, as well as protection from the vagaries of regional fuel quality. Te standard engine oil cooler, when the EcoDiesel is used with 5W30 synthetic oil, contributes to a 10,000-mile oil change interval. Te new turbo-diesel is designed and produced by VM Motori, a Chrysler Group diesel engine supplier since 1992. Putting the 'Eco' in EcoDiesel Te new EcoDiesel V-6 achieves 50-state emissions compliance for both tier II and BIN 5. A key enabler is the engine's cooled exhaust gas recirculation (EGR) system, which is controlled by electric valves instead of the conventional pneumatic variety. Te system also contributes to rapid start-up. Te new EcoDiesel is also compatible with B-20 biodiesel. Te new 3.0L V-6 EcoDiesel is among today's most advanced diesel engines. Its emissions are 60-percent less than those produced by diesel powertrains 25 years ago. A state-of-the-art selective catalytic reduction (SCR) system also reduces emissions. It incorporates a unique diesel exhaust fuid (DEF) system that alerts the driver to low DEF levels, while also allowing the engine to maintain full power. Te Ram 1500 includes an insulated DEF tank with heated lines to mitigate the efects of cold-weather operation. It also features a passive cooling system that does not require engine coolant for the DEF injector. Te DEF tank holds eight gallons of fuid. Duty cycle determines reflls, but the average interval is about 10,000 miles. AF
