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.

Cummins ATLAS light-duty diesel surpasses fuel economy targets, with criteria emissions lower than Tier 2/Bin 2

Green Car Congress

The Cummins team not only surpassed all fuel-economy targets, but also achieved criteria emissions lower than the stringent Tier 2/Bin 2 levels. Test cycle fuel economy (mpg). The Highway Fuel Economy Test (HFET) and FTP-75 Test (city) cycles demonstrated fuel economy above 35 mpg (6.72

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 PSA has been a member of the HEDGE consortium (now at HEDGE-III ) since 2004.

Nissan to use mirror bore process on new 2.5L engine for Altima; highest volume application of technique

Green Car Congress

The leeway gained can go towards increasing fuel economy and engine power. This results in better cooling performance and less engine knocking, and the efficiency of the engine as a whole is improved. In the second stage, a special drill bit is used containing tiny bits of diamonds that were unfit for jewelry. The new 2.5L Yoshida, N.
