BorgWarner suggests Valve-Event Modulated Boost system can offer 6-17% fuel economy benefit over already downsized and turbocharged engines

Green Car Congress

The VEMB system uses a concentric camshaft, blow-down manifold and scavenge manifold to separate the exhaust event into two phases: high-energy blow-down to the turbo without pumping losses, and high-hydrocarbon scavenge to the EGR system.

HyBoost demonstrator debuts at LCV2011; 50% by swept volume downsizing with low-cost electrification

Green Car Congress

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

Advanced ADEPT 48V affordable mild hybrid on path to meet future ultra-low vehicle emissions

Green Car Congress

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.

KSPG shows new compact two-cylinder range extender for EVs, variable valve system

Green Car Congress

Automotive supplier KSPG Automotive (formerly Kolbenschmidt Pierburg), a subsidiary of Rheinmetall AG, and FEV have jointly developed a concept for a compact, 30 kW range extender for battery-electric vehicles. The automobile can thus be delivered with or without a range extender and allows for a modular design concept.

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

Green Car Congress

The Ricardo-led Advanced Diesel Electric Powertrain (ADEPT) project will apply 48V “intelligent electrification” concepts, mild hybridization and waste heat recovery in a Ford Focus diesel demonstrator. 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).

SwRI’s HEDGE Technology Eliminates Low-Speed Pre-Ignition in Highly Boosted Engines

Green Car Congress

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. Earlier post.).

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

Green Car Congress

The concept ensures long term energy storage for delivering short bursts of power to the VTES supercharger during vehicle accelerations and to the SpeedStart stop-start device during engine re-starts. Conversely, short bursts of power can also be absorbed by the SpeedStart generator to recharge the battery during vehicle decelerations.
