HyBoost concept achieving close to Prius-level CO2 emissions; aggressive downsizing with advanced boosting and micro-hybrid system

Green Car Congress

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.

FEV’s two-stage VCR system; 5-7% increase in fuel economy using variable length conrods

Green Car Congress

Use of a variable compression ratio (VCR) could be one technology approach to reducing fuel consumption in highly boosted (e.g., downsized, turbocharged) gasoline engine, as operating an engine with higher compression ratios at low load can increase fuel economy compared to operating an engine with fixed compression ratio.

Magnetic eCVT could replace conventional hybrid mechanical eCVT with likely 1-2% fuel economy improvement and other benefits

Green Car Congress

Preliminary testing results of a prototype of the magnetic eCVT presented at the conference suggest a likely 1-2% improvement in fuel consumption compared to a conventional hybrid system, along with the benefits of reduced system complexity, no lubrication, low battery charge swing (allowing either downsizing the battery or extending the life of the (..)

Valeo acquires electric supercharger business from Controlled Power

Green Car Congress

Highly efficient at low engine revolutions, electric superchargers make it possible to downsize engines. When coupled with an energy recovery system, electric superchargers can be used to create a cost-competitive hybrid solution that can deliver fuel savings of up to 20% in the standard European driving cycle, Valeo said.

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

Ford engineers also presented two other papers evaluating the effects of low to mid-level ethanol blends in spark-ignited engines at the conference. 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.

Hyundai outlines future powertrain strategy

Green Car Congress

Hyundai Motor Group this week outlined its latest powertrain technologies and future plans at the 12 th Hyundai-Kia International Powertrain Conference, held near the Hyundai Motor Group R&D Center in Korea. In keeping with the trend to downsizing, Hyundai has been expanding the application of Turbo Gasoline Direct Injection (T-GDI) engines.
