The characteristic differences in exhaust emissions, and fuel consumption analysis of unleaded gasolines produced by different oil companies in the Turkish market
In Turkey, the differences in the properties of gasolines that are taken from different petrol stations are intensively discussed. By taking this as a starting point, the main target of this project is to examine these differences and how they affect exhaust emissions. The properties of nine gasoline samples taken from nine different petrol stations that belong to three different oil companies ...

Trends of exhaust emissions from gasoline motor vehicles in the metropolitan area of Mexico city
Light duty gasoline vehicles account for most of CO, hydrocarbons and NOx emissions to the urban environment in the metropolitan area of Mexico City. In order to ameliorate air pollution, several control measures have been imposed in the last decade, such as: up-grade of gasoline's quality, stringent environmental standards, and catalytic converters. On the other hand and from the beginning of ...

Catalytic Exhaust Emission Control of Small Internal Combustion Engines
ABSTRACT Gaseous emissions present in the engine exhaust of on-road motor vehicles are subject to stringent exhaust emission 2ontrol standards for carbon monoxide (CO), hydrocarbons, and oxides of nitrogen (NOx). All major automobile manufacturers utilize three-way catalytic converters to meet these standards. There are millions of small engines in on-road and off-road applications whose ...

Prevent tail gas pollution and reject environmental hazards
Motor vehicle exhaust is the exhaust gas generated during the operation of motor vehicles, including carbon monoxide (CO), nitrogen oxides (NOx), hydrocarbons (HC) and solid suspended particles (PM), which is one of the culprits of air pollution. From the perspective of the current pollution situation, the vehicle exhaust emissions to a large extent exceed the self purification capacity of the ...

Explaining vehicle emissions – why do laboratory and road measurements differ?
The road transport sector is a major contributor to Europe’s emissions of greenhouse gases and air pollution. For certain pollutants, vehicles can emit substantially higher emissions on the road than official emissions tested in laboratories. A report released today by the European Environment Agency (EEA) provides a non-technical guide that describes the reasons for these often significant ...

Effect of fuel additives on performance and exhaust emissions of direct injection diesel engine operating on B20 waste fish oil
The ever increasing diesel consumption, rapid depletion of fossil fuels and environmental concern has prompted an intensive use of biodiesel produced from various sources. In this study, biodiesel (ethyl ester of fish oil) was prepared from fish oil and different blends of biodiesel–diesel (B20, B40, B60, B80 and B100) were examined in a single cylinder, constant speed, and direct injection ...

Combustion, performance and emission analysis of diesel engine fuelled with methyl esters of Pongamia oil
The methyl esters of vegetable oils, known as biodiesel are increasingly becoming popular because of their low environmental impact and potential as a green alternative fuel for diesel engine, and that they would not require significant modification of existing engine hardware. Methyl ester of Pongamia oil (PME) is derived through transesterification process. Experimental investigations have been ...

Emission Testing of Engines to be Installed in Non-Road Mobile Machinery
The European Commission has founded a project on emission testing – 'Emission Testing of Engines to be installed in Non-Road Mobile Machinery'. The project was undertaken by Abgasprüfstelle Berlin-Adlershof GmbH in Germany. The work is a part of emission inventory of spark-ignition engines to be used as a basis for a future amendment of the Directive 97/68/EC. The inventory covers seven ...

What Is A NOx Scrubber?
“NOx scrubber” refers to an air pollution control device used to reduce or eliminate nitrogen oxide (NOx) emissions from industrial processes, power plants, and other sources. Nitrogen oxides are a class of harmful pollutants that adversely affect human health and the environment. NOx scrubbers are designed to reduce these emissions by employing various chemical and physical ...

Case study - Organic particulate filtration
Overview A food products company that mixes various types of waxes and other components to make the base for chewing gums was faced with the issue of cleaning up a slightly odorous, visible emission being exhausted from two of their process lines. The components of the emission were hot particles of chewing gum and some volatile organic compounds (VOC's). The particles would quickly clog a ...
