Boundary Conditions - Direct Injecion for Cat-Heating Operating Points
For the investigations, the engine was operated at a speed of 1500 rpm and an intake pressure of 0.95 bar. Starting from the base operating point with early injection and... -
Flow Field - Direct Injecion for Cat-Heating Operating Points
PIV was used to measure the flow fields and their velocities. A double-pulsed high-speed Nd:YVO4 laser (Edgewave IS4II-DE, 532 nm) was formed into a laser cut with several... -
Spray_Average - Direct Injecion for Cat-Heating Operating Points
The spray was visualized using high-speed images of the Mie scattering of the fuel droplets. The liquid fuel was illuminated with a volumetrically expanded laser beam through... -
Video - Simulation of a direct injection in an internal combustion engine
CFD simulation of gasoline direct injection in the Darmstadt optically accessible engine. Injector is the 8-hole ECN Spray G with injection timing equal to 270 °bTDC (i.e. early...
