New split-cycle concept to control diesel HCCI combustion

Green Car Congress

A team from Universita degli Studi di Pisa (Italy) and Rolf Reitz at the University of Wisconsin-Madison are proposing a novel combustion concept—Homogenous Charge Progressive Combustion (HCPC)—based on a split-cycle principle to control HCCI combustion in diesel-fueled engines. ICEF2007-1743 (2007). Tamagna, D.,

Bombardier (now Alstom) to convert AGC hybrid trains to full battery power

Green Car Congress

One of our first sustainable mobility solutions was a dual-mode Autorail à Grande Capacité (AGC) train, designed and developed by its Crespin site in France; the AGC was the world’s first hybrid train when it entered service in 2007. The effort is part of France’s strategy to eventually phase diesel power out of its national rail fleet.

University of Wisconsin Researchers Investigating Dual-Fuel (Gasoline and Diesel) Partially Premixed Combustion for High-Efficiency, Ultra-Low Emission Combustion; 53% Thermal Efficiency

Green Car Congress

Researchers at the University of Wisconsin, led by Dr. Rolf Reitz, are investigating a blended dual-fuel (gasoline and diesel) concept to extend the operating range of partially premixed charge compression ignition combustion by using the varying fuel reactivity of the charge blend, which is determined in real time. SAE 2007-01-0191).

Hackenberg resigns from Audi Board of Management

Green Car Congress

The move comes as Volkswagen AG continues to work to address the diesel engine emissions cheating scandal. Hackenberg moved to Audi in 1985, where he took over the position of Head of Concept Development in 1989 and later led the technical project management for the entire product range.

UW-Madison engineer collaborating with entrepreneur on 6-cycle, external combustion engine; could be up to 30% more efficient than standard diesel

Green Car Congress

Shedd said the engine could be up to about 30% more efficient than a standard diesel engine, depending on the engine load and speed. The K6 engine represents a unique combination of previous concepts. In contrast, he says, the K6 can be made by modifying existing diesel engines in a way that is both realistic and manufacturable.
