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

Green Car Congress

Turbo boost can be controlled by changing the timing of the exhaust valves—no waste gate is required. Although this reduces the window of operation and fuel economy benefit to 2-4%, it also eliminates vehicle adaptation cost. Total cost of implementation is much less than $10/1%, he said. and Sisson, J.

ALABC: 48V mild hybrids can meet emission targets with CO2 reductions of 15-20%

Green Car Congress

The T-Hybrid (based on a Kia Optima) ( earlier post ) and the ADEPT (based on a Ford Focus) ( earlier post ) both utilize an advanced 48V lead-carbon battery system with bolt-on electrical components that allow for significant engine-downsizing without loss in performance. liter engine the performance of a 1.8

GMZ-led project tracking to deliver vehicular thermoelectric generators for Bradley Fighting Vehicle, Honda Accord

Green Car Congress

Thermoelectric materials convert temperature differences into electric voltage; a TEG in a vehicle is designed to convert waste heat to power. As part of the project work, GMZ has also reduced the cost of its HH material compared to the current production material from from $180/kg to $75/kg and has improved the power density from 5.5

Viable exhaust-driven on-board ethanol reforming for improvements in fuel economy and emissions

Green Car Congress

Because exhaust-driven reforming uses only waste engine heat, it avoids this efficiency hit, the authors note. However, they add, this benefit comes at the cost of a substantial design complication: the reformer must serve as both a reactor and a heat exchanger between the fuel and the exhaust stream.
