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. or so, according to Thomas, resulting in the total possible benefits ranging from about 6% to 17%.

On the other hand, it is well known that in an internal combustion engine up to 35% of the energy developed by the fuel combustion is dissipated in the exhaust gases. The OSU EcoCAR prototype vehicle features an extended-range electric architecture with a downsized 1.8L Exhaust gas exergy map of EcoCAR engine.

Advantage EV

Electric Auto Association

Here’s what two organizations— Resource-Media and Recurrent —had to say about the advantages of electric vehicles (EVs) in frigid weather. Newer EVs have larger battery capacities, allowing for longer ranges and protecting against performance losses. Millions of Americans had a very challenging December with record cold temperatures.

Update on DOE Co-Optima project to co-optimize fuels & engines; goal of 30% per vehicle reduction in petroleum

Green Car Congress

The Co-Optima team is working to extend the knowledge base resulting from simulations with petroleum-derived fuels and ethanol to the broader range of fuels and fuel properties available from biomass resources. What the program has not done to this point is add blended power or extended-range architectures (i.e.,
