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. The very fast charge allows us to downsize the battery without incurring range anxiety.

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

Green Car Congress

Christopher Thomas, BorgWarner VP, Advanced Engineering, Engine Group and VP, Advanced Engineering, Drivetrain Group presented the basic concepts of VEMB and current BorgWarner test results at the recent SAE 2012 High Efficiency IC Engine Symposium. Total cost of implementation is much less than $10/1%, he said. and Sisson, J.

This common core also provides greater confidence in the robustness of prototypes, while minimizing the cost of variants further supports the development of 48V systems. SR machines are ideally suited to this concept of low cost development, while reducing the cost of production components. —Nick Pascoe.

DOE awards Envera $2.8M to develop and to test efficient variable compression ratio engine

Green Car Congress

The new engine will achieve high efficiency using the Atkinson Cycle with an 18:1 compression ratio, combined with aggressive engine downsizing. Engine downsizing is a key tool in improving fuel economy. When loads on the engine are low the compression ratio can be raised to as much as 18:1, Envera said.

Delphi develops new high-pressure common rail systems for heavy-duty and light-duty engines; Euro VI and beyond

Green Car Congress

Delphi presented the work in a technical paper “Development of High-Pressure Common Rail Systems Incorporating Advanced Electronic Control Strategies for Future Heavy-Duty Vehicles,” at the 33 rd Vienna Motor Symposium last week. This concept system is expected to be ideal for heavily downsized applications and developing markets.

Pinnacle 4-stroke opposed-piston SI engine shows fuel economy improvements of between 30-60% at light loads, 12-30% at medium loads over conventional

Green Car Congress

The company presented these latest test results in a paper at the SAE 2012 World Congress in Detroit. With the extended lean operation of the sleeve-valve engine, NO x emissions remain low for light to medium loads and rise back to typical levels during the brief enrichment periods required to maintain competitive BMEP levels at higher loads.
