"Investigation on Particle-Induced Pre-Ignitions in an SI Engine";
Vortrag: ICE Workshop, STAR Global Conference 2014, Wien (eingeladen); 17.03.2014 - 19.03.2014.

For downsized SI-engines under high load uncontrolled self-ignitions occur already before spark timing
The resulting mega-knock events lead to engine damage
Pre-ignition limit the downsizing potential
Knowledge about the initiation mechanism is crucial!
In the presented work, a turbocharged SI engine with direct injection was used to analyze the occurrence of pre-ignition
Numerical investigations and accompanying video observations at the engine test bench to verify initiation mechanisms of pre-ignition
