“…The high nucleation rate has been attributed to the reduction in solid particle surface by the DPF, which enhances the homogeneous nucleation of sulfuric acid vapor [6]. Elimination of these particles will require strict control of the sulfur in both the fuel and the lube oil [7][8][9].…”

This paper investigates the effect of lubrication oil on the physical and chemical characteristics of the particulate matter (PM) emitted from a Euro 4 diesel vehicle. Two different lubrication oils were examined. A fully synthetic ACEA grade B3 service-fill oil of low sulfur content (1760 ppm wt.) falling into the 0W-40 SAE viscosity grade and a mineral ACEA B2-98 motor oil of high sulfur (8890 ppm wt.), falling into the 15W-40 SAE viscosity grade. To exclude interferences from the fuel derived sulfur, a rather sulfur-free fuel (< 10 ppm wt.) was used in the experiments. The experiments included steady state tests, the certification cycle and real-world highspeed transient driving conditions. The properties measured included total particle mass collected on Teflon-coated filters, total particle number measured by a condensation particle counter, size distributions determined by a scanning mobility particle sizer. Chemical analysis was performed to investigate the metallic and the ionic character of the particulate matter for the different lubes. Results showed that the vehicle complies with the Euro 4 emission limits when tested over the type-approval NEDC regardless of the lubrication oil used. Both PM mass and number were drastically reduced with particle filter.

“…Vehicle operation characterized by frequent stop-and-go and extended idle periods could result in higher lubrication oil consumption. This is based on the findings that idle operation result in lower incylinder pressures and therefore would result in increased oil consumption (Anderson et al, 2004). Since current natural gas engines operate on a SI engine platform, lubrication oil consumption mechanisms would be similar to those reported by Anderson et al (Anderson et al, 2004).…”

Since current natural gas engines operate on a SI engine platform, lubrication oil consumption mechanisms would be similar to those reported by Anderson et al (Anderson et al, 2004). Further, Zielinska et al have shown that PAH emissions in gasoline engines, closely resemble PAH composition of used lubrication oil and not fuel (Zielinska et al, 2004).…”

Heavy-duty natural gas engines compliant with the 2010 EPA emissions standards have a clear advantage over diesel engines in meeting regulations with minimal after-treatment configuration. Heavy-duty natural gas engines are largely promoted as a cleaner burning engine with respect to low PM mass emissions. However, lack of sufficient data and literature on the exhaust emissions from advanced natural gas engines and the potential adverse health effects has raised concern amongst regulatory agencies. Also, the ammonia emissions from three-way catalyst equipped heavy-duty natural gas engines could be a major contributor to the formation of secondary PM in the atmosphere This CARB funded study focuses primarily on characterizing the toxicity of the volatile fraction of PM from advanced heavy-duty natural gas engines. The objective of the study also includes characterizing the unregulated species of the exhaust together with number concentration and size distribution of ultrafine nanoparticle emissions. CNG fueled transit buses were tested on WVU's heavy-duty chassis dynamometer in Stockton, CA. A wide array of TABLE OF CONTENTS

“…In addition, a small proportion of atomized and evaporated lubrication oil escape oxidation and form the volatile or semi volatile organic compounds generally called soluble organic fraction (SOF) in the exhaust. In fact, Andersson et al [46] showed in their study that sulfur and phosphorous contents of lubrication oil that enter the chamber during combustion contribute to the engine exhaust particles formation.…”

“…First, the sulfur and phosphorous contents of lubrication oil that could have entered the combustion chamber affected exhaust particle number emissions in the NMP range. It has been shown by Andersson et al[46] that sulfur and phosphorous contents of the lubricant that escaped into the chamber lead to higher number of exhaust particles emitted in the NMP range. The sulfur content of the test fuels have little or no effects on nanoparticles emissions because of the very low sulfur concentrations (between 1-2 ppm concentrations) of the fuels.…”
