Structure and Chemistry of Soot and Its Role in Wear of Diesel Engines

Environmental regulations to reduce the emissions using exhaust gas recirculation (EGR) have resulted in higher soot level in the crankcase oil of diesel engines. Longer drain intervals have resulted in engines running 80000 kilometers or more before an oil change. This results in longer residence t...
