FCA US upgrades 3.6L Pentastar V-6; 2-step VVL, cooled EGR; up to 6% better fuel economy

Green Car Congress

Pentastar, first introduced in 2009 ( earlier post ), was the first of an all-new line of V-6 engines intended to improve fuel efficiency across the Chrysler, Jeep and Dodge lineup. Depending on the application, the redesigned V-6 delivers fuel-economy improvements of more than 6% while increasing torque more than 14.9%.

Daimler Trucks NA SuperTruck achieves 115% freight efficiency improvement over 2009 baseline; 50.2% engine BTE

Green Car Congress

These tests resulted in the combined 115% freight efficiency improvement over a 2009 baseline truck. Friction-reducing measures include a variable speed water pump, a clutched air compressor, low-viscosity oil and an improved cylinder kit. This reduces friction, and increases efficiency and fuel economy. mpg (19.26

Audi banking on Gen 2 3.0L TDI diesel for US sales; calls for a “fair shot” for diesel

Green Car Congress

Do they receive HOV access for their improved fuel economy and ultra low emissions? In fact in 6 of the states, diesel fuel is penalized with additional state taxes. So diesel fuel gets taxed twice or penalized twice at the federal and state level. Changes in the exhaust manifolds and turbo from Gen 1 to Gen 2.

University of Wisconsin Researchers Investigating Dual-Fuel (Gasoline and Diesel) Partially Premixed Combustion for High-Efficiency, Ultra-Low Emission Combustion; 53% Thermal Efficiency

Green Car Congress

Rolf Reitz, are investigating a blended dual-fuel (gasoline and diesel) concept to extend the operating range of partially premixed charge compression ignition combustion by using the varying fuel reactivity of the charge blend, which is determined in real time. SAE 2001-01-0655), and optimizing fuel reactivity (Bessonette et al.,
