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

Green Car Congress

in August and September 2015—the highest share in more than a decade, according to data from the US Energy Information Administration (EIA). One significant trend is engine downsizing coupled with turbocharging. The higher the octane rating, the greater the resistance to preignition, the fundamental cause of engine knock.

Bosch leading Direct4Gas consortium to develop direct injection for monovalent natural gas engines

Green Car Congress

Bosch is leading a consortium in a German government-funded project to develop a direct injection system for monovalent natural gas engines—i.e., engines that run exclusively on CNG. Today’s CNG vehicles are generally bivalent, running on gasoline and CNG with engines designed for gasoline direct injection.

GM Highlights Engineering Advances With Second-Generation Fuel Cell System and Fifth-Generation Stack; Poised for Production Around 2015

Green Car Congress

GM’s second-generation fuel-cell system (engineer included for scale.) The new system, where we have adopted a pretty radical change in the architecture itself, downsizes dramatically, takes 100 kg of the mass out, and takes the size down to half of that of the Equinox. Click to enlarge. The new second-generation system is to the left.
