In order to assess the significance of PM in ambient air, it is necessary to evaluate their physical and chemical characteristics as well as identify their major emission sources. On a global scale, particulate matter in the atmosphere arises mainly from the combustion process of motorized vehicles, but natural sources are still considered as.

characterize the physical and chemical composition and the mutagenicity of emissions from two heavy-duty diesel engines operated with low-sulfur diesel fuel at a constant speed under two different steady-state load conditions, with and without an exhaust aftertreatment devices. A. Tsolakis's research works with 2, citations and 8, reads, including: Characterization of particle emission from thermoplastic additive manufacturing.
Fine dust and particulate matter (PM) emissions from combustion processes, especially from diesel combustion, may cause serious health problems. The exhaust gas aftertreatment of diesel engines becomes increasingly complicated due to tightening emission standards [1,2,3]. Downloadable (with restrictions)! Metal-based fuel-borne catalysts (FBCs) have been used with diesel fuels to effectively reduce soot and diesel particulate matter (DPM) emissions from both on-road and off-road applications. However, there is a lack of detailed investigations on the potential changes in the properties of particulates, when FBCs-doped fuels are combusted in diesel engines.

Size, density, and composition of diesel particles Diesel particles as well as particles from other combustion sources are a complex mixture of elemental carbon (EC), a variety of hydrocarbons (HC), sulfur compounds, and other species.
Particles differ in size, composition, solubility and therefore also in their toxic by: The techniques used to characterize the chemical and physical nature of particulates in diesel exhaust emissions are reviewed.
The emphasis is on understanding the broader aspects of the fundamental nature of not only diesel particulates, but particulate systems in general. The Physical and Chemical Character of Diesel Particulate Emissions-Measurement Techniques and Fundamental Considerations The techniques used to characterize the chemical and physical nature of particulates in diesel exhaust emissions are by: Get this from a library.
The physical and chemical character of diesel particulate emissions: measurement techniques and fundamental considerations. [William H Lipkea; J H Johnson; Carl T Vuk; Society of Automotive Engineers.] -- Collection methods are examined with examples given from current diesel dilution techniques.
Probes, sampling lines, and instrumentation are considered. The emission of diesel exhaust particulates is associated with potentially severe biological effects, e.g., cancer. The aim of the present study was to apply multivariate statistical methods to identify factors that affect the biological potency of these exhausts.
Ten diesel fuels were analyzed regarding physical and chemical characteristics. Particulate exhaust emissions were sampled after Cited by: Dynamometer testing was conducted using model year and GDI passenger cars on California E10 gasoline fuel over the LA92 cycle.
The physical, chemical, and toxicological properties of the particulate emissions are discussed in the context of the influences of the driving cycle and engine technology. Experimental An analysis of physical and chemical properties of Fischer−Tropsch fuel gas-to-liquids (GTL) blends with a conventional diesel was conducted.
Then, engine performance, combustion, and emission investigations were performed to better understand the differences in regulated emissions between diesel, GTL, and their blends using a six-cylinder turbocharged direct-injection compression ignition.
A chassis dynamometer study was carried out by the University of Southern California in collaboration with the Air Resources Board (CARB) to investigate the physical, chemical, and toxicological characteristics of diesel emissions of particulate matter (PM) from heavy-duty vehicles.
These heavy-duty diesel vehicles (HDDV) were equipped with advanced emission control technologies, designed. This paper discusses the physical−chemical properties of ethanol−biodiesel blends considered as fuel for diesel engines.
Attention is focused on the properties that significantly influence the injection, the engine characteristics, and subsequently, the exhaust emissions. In this context, the following properties have been investigated experimentally: fuel stability, density, viscosity.
An investigation on the physical, chemical and ecotoxicological characteristics of particulate matter emitted from light-duty vehicles. Environmental Pollution(), (c) Particulate-phase emissions. Diesel particles are aggregates of spherical primary particles of – µm (National Research Council, ).
Those generated under laboratory conditions in dilution tunnels have mass or volume median diameters ranging from to µm, depending on the operating conditions (Cheng et al., ). Diesel exhaust is the gaseous exhaust produced by a diesel type of internal combustion engine, plus any contained composition may vary with the fuel type or rate of consumption, or speed of engine operation (e.g., idling or at speed or under load), and whether the engine is in an on-road vehicle, farm vehicle, locomotive, marine vessel, or stationary generator or other.
Physical, chemical, and biological characterization data for the particulate emissions from a Caterpillar diesel engine with and without Corning porous ceramic particulate traps are presented. Measurements made at EPA modes 3,4,5,9,10 and 11 include total. This review examines the chemical properties of particulate matter (PM) in diesel vehicle exhaust at a time when emission regulations, diesel technology development, and particle characterization techniques are all undergoing rapid change.
The aim is to explore how changes in each of these areas impact the others. Bianca Maria Vaglieco's 19 research works with 8 citations and reads, including: Influence of water injection on combustion identified through spectroscopy in an optical direct injection spark.
ABSTRACTThe growing concern about air quality and the impact exhaust particles can have on the environment has resulted in the increased use of alternative fuels. A sampling campaign from a conventional heavy diesel engine operated in typical transient cycle or steady-state condition, and running on diesel, 30% biodiesel in diesel, and % biodiesel was carried out.
The particulate. The effect of fuel changes on diesel oxidation catalyst performance was studied by comparing the physical, chemical and biological character of the particulate emissions using three different fuels.
Baseline (uncatalyzed) emissions were also compared for these same fuels. The fuels used for this stu. The Influence of a Low Sulfur Fuel and a Ceramic Particle Trap on the Physical, Chemical, and Biological Character of Heavy-Duty Diesel Emissions This study was conducted to assess the effects of a low sulfur (diesel emissions during both steady-state operation and.
There is a lack of detailed investigations on the effects of butanol addition to diesel/biodiesel blends on particulate emissions.
This study represents the first attempt of its kind to fully evaluate the potential impact of diesel–biodiesel–butanol blends on engine performance, physical, chemical and toxicological properties of the particulates emitted by a single cylinder direct.
