ADEPT project to apply gasoline engine HyBoost system to diesel; 48V architecture; full hybrid fuel economy at much lower cost

Green Car Congress

The project aims to deliver full hybrid equivalent fuel economy and performance with less than 70 g/km CO 2 emissions as measured over the European Drive Cycle, but at a significantly lower cost. version of its vehicle (a 2009 Ford Focus) but with fuel economy and CO 2 emissions approaching those of a Prius.

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. The extent of fuel-air mixing can be affected by injection system design. Credit: ACS, Zimmerman et al.

Ford / AVL study concludes mid-level ethanol blend attractive as a long-term future fuel for use in optimized engines in US

Green Car Congress

As a result, as the ethanol content of the fuel is increased, the fuel economy and driving range for a given fuel tank size are reduced. Downsizing/downspeeding. Increased ethanol content enables improved efficiency by reducing or eliminating the need for fuel enrichment. Volumetric fuel economy.

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.

Renault 2010 Environment Workshop, Part 1: Combustion Engine Technology and Product Plans

Green Car Congress

Renault’s ongoing downsizing strategy is aimed at reducing the cubic capacity of its engines in order to bring down fuel consumption and CO 2 emissions, without detracting from performance. The downsizing process involved shortening the piston stroke by reducing the size of the crank pin and conrod assembly. Select Engines.

Controlled Power Technologies Packages Its Switched Reluctance Systems in ‘RegEnBoost’ System for Enhanced Support for Downsizing

Green Car Congress

Power for the battery and VTES electric supercharger is not only supplied by the SpeedStart ISG but also the TIGERS exhaust driven turbo-generator. Small displacement engines offer excellent CO 2 and fuel economy benefits; they have lower parasitic losses and operate more efficiently under part load conditions.
