The impact of sulphur content of diesel fuel on ultrafine particle formation

Early this year the Australian Department of Environment and Heritage commissioned a desktop literature review with a focus on ultrafine particles including analysis of health impacts of the particles as well as the impact of sulphur content of diesel fuel on ultrafine particle emission. This paper summarizes the findings of the report on the link between the sulphur content of diesel fuels and the number of ultrafine particles in diesel emissions. The literature search on this topic resulted in over 150 publications. The majority of these publications, although investigating different aspects of the influence of fuel sulphur level on diesel vehicle emissions, were not directly concerned with ultrafine particle emissions. A specific focus of the paper is on: ----- ----- summary of state of knowledge established by the review, and ----- ----- summary of recommendations on the research priorities for Australia to address the information gaps for this issue, and on the appropriate management responses.

A comparative study of the number and mass of fine particles emitted with diesel fuel and marine gas oil (MGO)

The current investigation reports on diesel particulate matter emissions, with special interest in fine particles from the combustion of two base fuels. The base fuels selected were diesel fuel and marine gas oil (MGO). The experiments were conducted with a four-stroke, six-cylinder, direct injection diesel engine. The results showed that the fine particle number emissions measured by both SMPS and ELPI were higher with MGO compared to diesel fuel. It was observed that the fine particle number emissions with the two base fuels were quantitatively different but qualitatively similar. The gravimetric (mass basis) measurement also showed higher total particulate matter (TPM) emissions with the MGO. The smoke emissions, which were part of TPM, were also higher for the MGO. No significant changes in the mass flow rate of fuel and the brake-specific fuel consumption (BSFC) were observed between the two base fuels.

Influence of the diesel fuel sulfur content on the formation of nanoparticles

In recent years fine and ultra fine particles emitted from internal combustion engines have attracted an increasing level of attention. This attention has arisen from epidemiological studies conducted by a number of research groups and pointing to the health effects resulting from inhalation of fine particles. Previous studies on the influence of fuel sulfur level on diesel vehicle emissions were mainly concentrated on particle mass emissions. This study aims at investigating the influence of the reduction of diesel fuel sulfur level on the emission and formation of nanoparticles

USE OF BARU OIL (Dipteryx alata Vog.) TO PRODUCE BIODIESEL AND STUDY OF THE PHYSICAL AND CHEMICAL CHARACTERISTICS OF BIODIESEL/PETROLEUM DIESEL FUEL BLENDS

We describe production of methyl and ethyl esters derived from baru oil (Dipteryx alata Vog.). Water and alcohols are removed from the biodiesel obtained by simple distillation. We study the acidity, density, iodine number, viscosity, water content, peroxide number, external appearance, and saponification number of the oil, its methyl and ethyl esters (biodiesels) and their blends (B5, B10, B15, B20, and B30) with commercial diesel fuel.

Diesel fuel release at Caterpillar Proving Grounds, East Peoria, Illinois : Tazewell and Woodford Counties /

On February 18, 2011, Caterpillar Tractor Company, Inc. (CAT) was notified by the Woodford County Emergency Management Agency that residents along Ten Mile Creek had noticed a fuel odor. CAT personnel checked outfalls on the bluff below and the Proving Grounds fuel station and discovered some diesel fuel seeping into a ravine which continues to Ten Mile Creek. An initial investigation around the fueling facility revealed a diesel leak in an underground line that feeds the fuel dispensers. Diesel fuel is used on the Proving Grounds property to power the earth-moving equipment being tested there. At the time the leak was found, CAT began excavating to remove the source and to find the extend of the leak. The fuel had followed a down-hill slope to a ravine on CAT property, ran down the ravine and impacted Ten-Mile Creek (about one-half mile away) with a visible sheen of diesel fuel on top of the water.
