variant but with fuel economy of a strong hybrid. HyBoost achieves this by combining aggressive 50% downsizing of the engine with an electric supercharger for transient low-speed performance, and a micro-hybrid stop-start and energy recuperation systems, Boggs said.

New Delphi Technologies 500+ bar GDi system cuts gasoline particulate emissions by up to 50%, reduces fuel consumption

Green Car Congress

Reducing engine-out emissions cuts tailpipe emissions in the crucial period before catalyst light-off and reduces the need for costly aftertreatment systems. The industry has long recognized that increasing injection pressure to 500+ bar could substantially cut engine-out particulates while improving CO2 emissions and fuel economy.

U Toronto team assess the climate trade-off between reduced CO2 and increased Black Carbon from GDI engines

Green Car Congress

The upside of gasoline direct injection (GDI) engines is widely seen as being improved fuel economy coupled with an increase in specific power (especially with turbocharging), enabling significant downsizing.

Study finds technology cost of achieving European 2020 LDV CO2 targets more than offset by resultant fuel savings

Green Car Congress

The technical and macro-economic study, commissioned by the European Climate Foundation, focuses on light-duty vehicles. This derives from the fact that most of the money spent on fuel leaves the European economy, while most additional money spent on fuel-saving technology remains in Europe as revenues for the technology suppliers.

Taking another look at methanol as an alternative transportation fuel for the US

Green Car Congress

A bridging option is to use methanol derived from natural gas, with a CO2 intensity that is no worse than conventional fuels. There is also the possibility of achieving greenhouse gas reduction by CO2 sequestration in the methanol generation process. Performance of methanol FFVs—i.e., Earlier post.).
