In implementing this 50% downsizing by swept volume, the research team delivered zero degradation in driveability, performance or acceleration. Click to enlarge. Earlier post.). The HyBoost concept is based on a 2009 Ford Focus in which a 2.0L naturally aspirated four-cylinder gasoline engine has been replaced with a 1.0L

The final results will be presented at the UK’s LCV2016 event on 14-15 September. The concept of “intelligent electrification” enables highly aggressive engine downsizing and down-speeding beyond what might normally be possible other than through more expensive hybridization approaches. ADEPT powertrain architecture.

This combined combined aggressive 50% downsizing of the engine with an electric supercharger for transient low-speed performance and a 12+X volt micro-hybrid stop-start and energy recuperation systems. It is capable of operating in exhaust temperatures up to 850 °C, at speeds up to 60,000 rpm and delivering a peak power of 2 kW (@12V).

LSPI is considered an impediment to aggressive engine downsizing to reduce carbon dioxide emissions. Low-speed preignition events are random, infrequent occurrences that happen at low speed and high torque, and their causes are not completely understood. Earlier post.).

to eliminate turbo lag—in support of aggressive engine downsizing. The system can operate without a wastegate, using electrical energy storage to prepare for the next acceleration event. Fuel flexibility requires the capability to handle diverse air/fuel ratios, exhaust gas volumes, and mean effective pressures.

Southwest Research Institute (SwRI) has successfully demonstrated that its HEDGE (High-Efficiency, Dilute Gasoline Engine) technology, using cooled exhaust gas recirculation (EGR) and advanced ignition systems, suppresses low-speed pre-ignition in turbocharged gasoline direct-injection engines.
