Congratulations to Christian Disch from the Karlsruhe Institute of Technology for his Best Paper Award at the JSAE conference in Kyoto

LaVision congratulates Dipl.-Ing. Christian Disch from the KIT (Karlsruhe Institute of Technology) for receiving the Best Paper Award during the JSAE PFL conference in Kyoto.
The presented paper “Experimental Investigations of a DISI Engine in Transient Operation with Regard to Particle and Gaseous Engine-out Emissions” (SAE 2015-01-1990) shows results from in-cylinder measurements recorded with LaVision’s Internal Combustion Optical Sensor (ICOS) system. The Air-Fuel-ratio was recorded at outstanding time resolution to analyze consecutive cycles during a dynamic driving cycle.
The ICOS Fuel spark plug sensor measured the evolution of the local lambda value as a response of the ECU (engine control unit) behavior to a tip-in (fast driver’s load change request) at crank angle resolution. The transient air-fuel-ratio could clearly explain emissions arising from the dynamic driving cycle and attribute these to individual engine cycles and engine control settings.
