The growth in population (Fig. 1) plus the growth in energy consumption per person(1) have combined together to give dramatic increases in both air and water pollution problems. The automotive vehicle has been a significant contributor to air pollution on a total mass basis (Fig.

2014 IEEE Workshop on Environmental, Energy, and Structural Monitoring Systems Proceedings, 2014
Mopeds and motorcycles are broadly used and represent a large share of motorized vehicles, above all in urban environment of Asia and Europe. As a result the relative contribution of the emissions of powered two-wheelers to the total air pollution increased considerably in the last years.

Effect of Temperature on Exhaust Emissions
SAE Technical Paper Series, 1974<div class="htmlview paragraph">A program has been completed to study the effects of ambient temperature on exhaust emissions. It consisted of determining the cold start emission levels of two late model passenger cars at temperatures of +70, +40, and -10°F with two test fuels of different midrange volatility characteristics.</div> <div ...

Exhaust Emissions of Light Aircraft
SAE Technical Paper Series, 1971<div class="htmlview paragraph">The purpose of this study was to evaluate exhaust emissions of representative aircraft as they were flown in a normal manner. At the same time, the extent of afterburning was measured by sampling the exhaust plume downstream of the exhaust stack and comparing the plume composition, corrected for dilution, to the ...

Increasing energy consumption, which is mainly covered by the energy contained in fossil fuels, have made air quality a critical issue. The quality of the air we breathe depends on a wide range of factors. In addition to emissions from industry, homes, and power plants, the exhaust gas generated by motor vehicles also plays a significant role.

SAE Technical Paper Series, 1968
<div class="htmlview paragraph">With the exception of nitric oxide, exhaust emissions from a wide variety of gas turbine engines for both land and air propulsion are at levels below present and projected air pollution standards. It is proposed that emission levels be reported on a basis related to fuel consumption.

The ABCs of Engine Exhaust Emissions
SAE Technical Paper Series, 1971<div class="htmlview paragraph">This paper indicates why certain exhaust constituents from automotive vehicles are considered pollutants, describes the formation of these pollutants in automotive operation, and details techniques being used and considered to control these pollutants.</div> <div class="htmlview paragraph">The formation

Exhaust Emission Characteristics
1984The engine-out exhaust emissions of CO, HC, and NOx vary as a function of air-fuel ratio as well as several other parameters such as ignition timing and EGR. Here we shall consider only the relationship to air-to-fuel ratio (A/F). A general relationship between engine out CO, HC, and NOx emissions and A/F is shown in Figure 1.

Vehicle maintenance and exhaust emissions
Science of The Total Environment, 1994Abstract In most of the world, light duty vehicles and the engines used in heavy duty vehicles are designed to comply with legal limits for exhaust emissions. The manufacturer must demonstrate that this is the case by submitting vehicles or engines for testing.

WEIGHING AUTOMOTIVE EXHAUST EMISSIONS
SAE Technical Paper Series, 1969<div class="htmlview paragraph">For more than a decade, the need for measuring exhaust emissions on the basis of weight of emissions per mile has been known. Because of the complexity involved in mass emission measurements, the original procedures and standards were expressed in terms of concentration.
