New split-cycle concept to control diesel HCCI combustion

Green Car Congress

A team from Universita degli Studi di Pisa (Italy) and Rolf Reitz at the University of Wisconsin-Madison are proposing a novel combustion concept—Homogenous Charge Progressive Combustion (HCPC)—based on a split-cycle principle to control HCCI combustion in diesel-fueled engines. —Musu et al.

GE study finds 5% of worlds natural gas production wasted per year by flaring

Green Car Congress

Although Nigeria has reduced flare gas emissions by 28% from 2000 levels, the country’s oil industry still wastes 15bcm of natural gas every year. —David Victor, director of the Laboratory on International Law & Regulation at the University of California San Diego.

Reducing Black Carbon Emissions and Ground-Level Ozone Would Provide Immediate Benefit Against Climate Change

Green Car Congress

The piece was co-authored by Scripps Institution of Oceanography at UC San Diego climate and atmospheric scientist V. Black carbon is produced largely by diesel vehicles and the burning of biomass, including in cookstoves in developing countries like China and India. Besides a danger to breathe, ozone lowers crop yields.

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

Green Car Congress

The OPGCI technology is attractive from an ARPA-E point of view as it potentially allows gasoline-fueled engines to operate at diesel-like efficiencies, with the reduced cost benefit of only requiring three-way catalysis and lower pressure (and hence lower cost) fuel injection systems. bar was measured at 2000 rpm, with 17.4
