Dalian team proposes jet controlled compression ignition to control PCCI phasing in a hybrid pneumatic engine

December 30, 2015

Researchers at the Dalian University of Technology have proposed a novel method to control premixed charge compression ignition (PCCI) phasing in internal combustion engines in all load operations. High-pressure air jet controlled compression ignition (JCCI) is based on a compound thermodynamic cycle and is implemented in a hybrid pneumatic engine (HPE) as proposed by Schechter in 1999.

The application of HPE is also beneficial to the fuel consumption and emissions because of its several flexible operation modes. A paper on the use of JCCI is published in the ACS journal Energy & Fuels.

$90M UR:BAN research initiative presenting results on ADAS and traffic management for cities; intelligent vehicles

October 07, 2015

In Düsseldorf, the 31 partners—automobile and electronics manufacturers, suppliers, communication technology and software companies, research institutes and cities—involved in the UR:BAN research initiative (Urban Space: user-friendly assistance systems and network management) presented the results of four years of work in a two-day event.

UR:BAN’s goal is to develop advanced driver assistance and traffic management systems for cities, with a focus on the human element in all aspects of mobility and traffic. The project pursued its objectives in three main thematic target areas: Cognitive Assistance; Networked Traffic System; and Human Factors in Traffic.
