Ricardo’s “deep” Miller cycle concept: Magma

Green Car Congress

The in-cylinder gases are thus expanded and cooled as the piston descends, before being re-compressed as the piston rises again. The expansion ratio on the exhaust stroke is much higher than the effective compression ratio; the longer expansion provides extra power to the crankshaft and extracts more energy from the combusted fuel.

Researchers Propose Solar-Driven Biomass Gasification Pathway for Synthetic Fuel Production

Green Car Congress

Hertwich and Xiangping Zhang, is to obtain an easy to handle fuel with near-zero CO 2 emission and reduced land-use requirements compared to first and second generation biofuels. The researchers modeled the production of methanol, which can be used directly as transport fuel or as input for DME and FT-diesel synthesis.

False Starts: The Story of Vehicle-to-Grid Power

Cars That Think

It occurred in the wake of the California electricity crisis of 2000 and 2001, when mismanaged deregulation, market manipulation, and environmental catastrophe combined to unhinge the power grid. In the early years of the automobile, battery-powered electric cars were competitive with cars fueled by gasoline and other types of propulsion.

New Gen4 smart electric drive; electrification of all smart models

Green Car Congress

With the onboard charger, in the USA and the UK the charging time is 2.5 This enables the smart electric drive to be charged in less than 45 minutes (0-80%) when local conditions allow three-phase charging. The programmed departure time can be used both for intelligent charging and for the pre-entry climate control.
