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

Green Car Congress

Together the partners have sought to demonstrate an extremely cost-effective, ultra-efficient gasoline engine in a C-segment passenger car delivering the performance of a baseline 2.0-liter In implementing this 50% downsizing by swept volume, the research team delivered zero degradation in driveability, performance or acceleration.

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 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. If we improve the responsiveness of small engines, then we can push for more efficient cars at low cost.

MAHLE Powertrain and White Motorcycle Concepts developing fully electric 3-wheeled motorcycle for police, emergency first responders

Green Car Congress

Because emergency services require high levels of availability and have an unpredictable demand, retail electric motorcycles are unlikely to present a cost-effective solution. Existing electric motorcycles have been designed with the retail market in mind, and can be both expensive and slow to charge.

Penn State team develops thermally modulated LFP battery; fast-charging, inexpensive, long-life for mass-market EVs

Green Car Congress

Furthermore, they found that the limited working time at the high temperature presents an opportunity to use graphite of low surface areas, thereby prospectively prolonging the EV lifespan to greater than two million miles. We developed a pretty clever battery for mass-market electric vehicles with cost parity with combustion engine vehicles.

Concept: Downsized and Supercharged Hybrid Pneumatic Engine for 30%+ Reduction in Fuel Consumption

Green Car Congress

Schematic of downsized and supercharged four-stroke hybrid pneumatic spark injection engine. The reduction in fuel consumption is obtained mainly through enabling the effective use of a heavily downsized engine, rather than from regenerative efficiency. However, this setup adds complexity and cost. [In Source: ETH Zürich.

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

Green Car Congress

As another method to avoid pumping losses and improve efficiency, Thomas described a low-cost virtual cylinder deactivation technology that delivers 90% of the fuel economy benefit of a full mechanical cylinder deactivation system. Total cost of implementation is much less than $10/1%, he said. —Christopher Thomas.
