Simulation study suggests ORC waste heat recovery system could deliver potential 7% improvement in fuel consumption in a PHEV on highway

Green Car Congress

Starting from a energy-based powertrain simulation model validated on experimental data from the PHEV, the researchers conducted a first- and second-law analysis to identify the potential for engine waste heat recovery, considering a variety of driving cycles and assuming the vehicle operating in charge-sustaining (HEV) mode.

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. Source: Borgwarner. Click to enlarge. The turbo will always be spinning.

Eaton contributing several components to DOE SuperTruck II program

Green Car Congress

The Eaton 48-volt mild hybrid accessory drive captures energy while driving and is used to keep the sleeper cab comfortable overnight without idling the engine. SuperTruck II is a continuation of the DOE’s SuperTruck initiative, which launched in 2010 with the goal to improve heavy-duty truck freight efficiency by 50%.

ARPA-E awards U-M $1.9M to develop advanced low-cost high-efficiency engine; boosting, highly dilute combustion and 48V system

Green Car Congress

The US Department of Energy’s (DOE’s) Advanced Research Projects Agency - Energy (ARPA-E) will award approximately $1.9 The performance is projected to match that of a naturally aspirated engine and have a 20% increase in fuel efficiency compared to a turbocharged downsized engine, at a cost that is half that of a mild-hybrid system.
