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 Cost of the new engine relative to gasoline baseline. Exhaust system configuration. Earlier post.).

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.

MECA report finds additional NOx emission reductions from new heavy-duty trucks achievable and cost-effective

Green Car Congress

This has resulted in higher catalyst loading per volume of substrate and led to downsizing of systems from those available in 2010. While the cost of new heavy-duty trucks has increased at approximately 1% per year, the cost of emission controls has come down, representing a lower percentage of the cost of a new truck.

CPT/AVL Study: New Generation of Micro-Hybrid Technologies Can Enable More than 25% Reduction in Fuel Consumption at Lower Cost Than Full Hybrid Drive Systems

Green Car Congress

Reductions in fuel consumption and CO 2 from base 2.0-liter liter ELC-Hybrid to downsized 1.4L VTES + SpeedStart. In combination with the VTES electric supercharger, this will create a cost effective micro/mild hybrid system which, when applied to a downsized 1.4-liter Click to enlarge.

CPT developing 48-volt electric supercharger for micro-mild hybrids

Green Car Congress

The higher-voltage variant will support moves by European vehicle manufacturers announced earlier this year to introduce 48 volt passenger vehicle power networks to help meet the requirement for lower fuel consumption and CO 2 emissions. —Guy Morris, CPT’s engineering director and chief technical officer.

Viable exhaust-driven on-board ethanol reforming for improvements in fuel economy and emissions

Green Car Congress

A team at Monsanto and colleagues at AVL Powertrain have successfully designed and demonstrated an onboard low-temperature ethanol reformer that can be driven by exhaust heat. A paper on their work is published in the ACS journal Energy & Fuels. Click to enlarge. Unlike high-temperature reforming, supplementary water is not required.

Achates OPGCI project targeting 50% fuel efficiency gains over downsized GDI engine at reduced cost

Green Car Congress

The engine should yield fuel efficiency gains of more than 50% compared to a downsized, turbo-charged gasoline direct injection engine, while reducing the overall cost of the powertrain system, said Fabien Redon, Vice President, Technology Development at Achates Power. Earlier post.) Earlier post.).
