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.

BorgWarner suggests Valve-Event Modulated Boost system can offer 6-17% fuel economy benefit over already downsized and turbocharged engines

Green Car Congress

The VEMB system uses a concentric camshaft, blow-down manifold and scavenge manifold to separate the exhaust event into two phases: high-energy blow-down to the turbo without pumping losses, and high-hydrocarbon scavenge to the EGR system. to 2 ratio points and maintain the same knock limit for an additional 3-4% improvement in fuel economy.

EIA: trends in downsized engine design leading to increased demand for higher-octane gasoline

Green Car Congress

This trend of increasing demand for higher octane gasoline is likely driven by changes in fuel requirements for light-duty vehicles (LDV) in response to increasing fuel economy standards, which will have widespread implications for future gasoline markets, according to EIA analysts. of the LDV market by 2025.

Eaton contributing several components to DOE SuperTruck II program

Green Car Congress

Eaton is supplying a number of leading-edge technologies that improve fuel economy and reduce emissions to Original Equipment Manufacturer (OEM) teams. Eaton’s CDA technology can operate at up to three to four bar BMEP at all speeds, which reduces emissions by improving aftertreatment thermal management while providing better fuel economy.

ADEPT project to apply gasoline engine HyBoost system to diesel; 48V architecture; full hybrid fuel economy at much lower cost

Green Car Congress

The project aims to deliver full hybrid equivalent fuel economy and performance with less than 70 g/km CO 2 emissions as measured over the European Drive Cycle, but at a significantly lower cost. version of its vehicle (a 2009 Ford Focus) but with fuel economy and CO 2 emissions approaching those of a Prius.
