This book was released on 2003 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: Detailed exhaust emission data have been taken from a Cummins N-14 single cylinder research engine in which the oil consumption was varied by different engine modifications. Low sulfur fuel was used, and oil consumption was varied by modifying the intake valve stem seals, the exhaust valve stem seals, the oil control ring and combinations of these modifications. Detailed measurements of exhaust gas particle size distributions and chemical composition were made for the various oil consumption configurations for a range of engine loads and speeds. The particulate mass was measured with TEOM and traditional gravimetric filter methods. Filter data for EC/OC, sulfates and trace metals have been taken and analyzed. The trace metals in the particulate mass serve as the basis for assessing oil consumption at the different operating conditions. The data indicate that the oil consumption for the steady state testing done here was approximately an order of magnitude below oil consumption values cited in the literature. We did measure changes in the details of the chemical composition of the particulate for the different engine operating conditions, but it did not correlate with changes in the oil consumption. Furthermore, the data indicate that the particle size distribution is not strongly impacted by low level oil consumption variations observed in this work.

This book was released on 2006 with total page 227 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diesel engines emit large quantities of fine particles to the atmosphere, on which numerous organic compounds are absorbed, such as PAHs, nitro-PAHs, and sulfur-containing PAHs. It is well established that exposure to PAHs and their derivatives may represent a high risk for human health. Considering its organic fractions and inhalable properties, diesel particulate matter (DPM) is considered a probable human carcinogen. The concerns of DPM health effects have simulated studies on DPM chemical composition and its formation mechanisms. This dissertation presents the results of an experimental investigation into the composition and formation mechanism of DPM at various engine operating conditions and fuel sulfur contents. The influence of sampling methods also was examined. High volume dilution sampling and ultrasonic assisted extraction methods were developed for collection and extraction of DPM. Gas chromatography/mass spectrometry (GC/MS) with selective ion chromatogram (SIC), tandem mass spectrometry (MS/MS) with selected ion monitoring (SIM), and gas chromatography with atomic emission detection (GC/AED) were applied for determination of numerous hydrocarbons and organosulfur species in diesel emissions. The results of the comparisons between DPM extracts, diesel fuel, and engine oil indicate that diesel fuel, engine oil, and combustion process were the three major sources of alkanes, organic acids, and PAHs and alkylated PAHs in DPM, respectively. As expected, the distribution of organic compounds between gas and particle phase diesel emissions was directly correlated with their vapor pressures. Adsorption of gas phase organics onto diesel particles was the predominant mechanism controlling the formation of diesel aerosols. This research revealed strong effects from engine operation conditions and sampling methods on the organic composition and formation mechanism of DPM, as well as the compound distribution. Higher engine loads caused the increase in DPM emission rate, its elemental carbon fraction, and the heavier components, which were pyrogenic species, formed during combustion processes, and may present greater health risks. The comparison between the results for dilution method and stack sampling method demonstrated that the dilution process significantly increased the organic fraction of DPM through the condensation of gas-phase organics. The research outcomes provide important knowledge for understanding DPM nature and formation mechanisms.

Book Synopsis Particulate Emissions from Vehicles by : Peter Eastwood
Download or read book Particulate Emissions from Vehicles written by Peter Eastwood and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: The public health risks posed by automotive particulate emissions are well known. Such particles are sufficiently small to reach the deepest regions of the lungs; and moreover act as carriers for many potentially toxic substances. Historically, diesel engines have been singled out in this regard, but recent research shows the need to consider particulate emissions from gasoline engines as well. Already implicated in more than one respiratory disease, the strongest evidence in recent times points to particle-mediated cardiovascular disorders (strokes and heart attacks). Accordingly, legislation limiting particulate emissions is becoming increasingly stringent, placing great pressure on the automotive industry to produce cleaner vehicles - pressure only heightened by the ever-increasing number of cars on our roads. Particulate Emissions from Vehicles addresses a field of increased international interest and research activity; discusses the impact of new legislation globally on the automotive industry; and explains new ways of measuring particle size, number and composition that are currently under development. The expert analysis and summary of the state-of-the-art, which encompasses the key areas of combustion performance, measurement techniques and toxicology, will appeal to R&D practitioners and engineers working in the automotive industry and related mechanical fields, as well as postgraduate students and researchers of engine technology, air pollution and life/ environmental science. The public health aspects will also appeal to the biomedical research community.
