Cummins progressing with lightweight downsized T2B2 diesel for pickup; 40% improvement in fuel economy over gasoline V8

Green Car Congress

At the US Department of Energy’s (DOE’s) Annual Merit Review meeting in Washington, DC last week, Michael Ruth from Cummins noted that the DOE program target for the project is a fuel economy (CAFE) target of 26 mpg (9.05 Exhaust system configuration. Earlier post.). l/100 km) for a vehicle of that size.

SwRI develops D-EGR demonstrator highlighting fuel-efficient, cost-effective engine; 10% and above fuel economy improvements

Green Car Congress

D-EGR is an engine and control concept that combines fuel reforming to produce hydrogen with high levels of exhaust gas recirculation (EGR) to achieve very high levels of thermal efficiency. In 2013, SwRI reported a 2.0-liter As will be presented at SAE World Congress, SwRI engineers modified the 2.0-liter

Lotus Omnivore Engine Shows Up To 10% Better Fuel Economy Than Spray-Guided GDI Engines; Achieves HCCI At Extremely Light Loads

Green Car Congress

Omnivore lays the foundations for a novel and pragmatic vision of a variable compression ratio engine concept suitable for production. The two-stroke cycle, conversely, does not suffer from significant throttling losses and in many ways is a more natural fit for automotive use. Simon Wood, Technical Director of Lotus Engineering.
