Diesel engines equipped with exhaust gas recirculation reduce NOx emissions: however, engine combustion causes large amounts of soot to be produced. This soot intermixes with the contaminates lubricants thereby adversely affecting engine durability. The behavior of soot with EGR and the process by which soot intermixes with lubricant was investigated. The study indicates that the amount of soot intermixing with lubricants is related to exhaust smoke and the EGR rate. Most of the soot intermixes with the oil film on the cylinder wall. Intermixing with blow-by gas is very small.
