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. to 2 ratio points and maintain the same knock limit for an additional 3-4% improvement in fuel economy.

Using the PHEV (Plug-In Hybrid Electric Vehicle) to Transition Society Seamlessly and Profitably From Fossil Fuel to 100% Renewable Energy

Green Car Congress

The alternative-fuel car evolved to reduce exhaust emissions and other problems derived from burning fossil fuels. The PHEV (Plug-in Hybrid Electric Vehicle), a subset of the electric car, combines a primary electric motor with a much smaller back-up engine fueled with a hydrocarbon/biofuel mix.
