Abstract
Many studies have been performed on diesel engine particulate matter emissions, but the influence of lubricants on emissions has only been considered a few times, and the effects of lubricant additives have yet to be investigated. We studied the influence of a pour point depressant additive (PPD) on particle emissions and particle size distributions from a four-cylinder turbocharged, inter-cooled engine with CF-4 15W-40 lubricant, using diesel or diesel containing the PPD. Changing the working conditions changed the number of particles emitted and the location of the peak particle size(s) emitted. The number of particles first increased and then decreased as the engine speed increased. Particle emissions were optimal at low engine speeds and high load, increasing with increasing engine speed.
