KAUST team develops computational model for simulating soot production in gasoline direct injection engines

Green Car Congress

Researchers at KAUST have developed a computational model capable of simulating soot production inside gasoline direct injection (GDI) engines. Although today’s passenger vehicle engines are cleaner and more fuel efficient, GDI exhaust can still contain significant numbers of nanoscopic soot particles that are small enough to penetrate the lungs and bloodstream. This new computer model could help car makers improve their engines to cut soot formation.
