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. 2010) Valve-Event Modulated Boost System, SAE Technical Paper 2010-01-1222 doi: 10.4271/2010-01-1222.

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

Green Car Congress

In implementing this 50% downsizing by swept volume, the research team delivered zero degradation in driveability, performance or acceleration. 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 three-cylinder EcoBoost engine.
