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.

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.

Design and analysis of exhaust manifold of the spark ignition engine for emission reduction
International Journal of Ambient Energy, 2018The design geometry of exhaust manifold plays a vital role in smooth combustion and emission reduction of the spark ignition engine. In this work, by analysing and comparing the exhaust gas back pressures and its velocities of different types of manifold

An Automobile Exhaust Emission Model
SAE Technical Paper Series, 1974<div class="htmlview paragraph">A mathematical model of an automobile's emission rate is described. This model can be used to calculate the amounts of hydrocarbons, carbon monoxide, and oxides of nitrogen emitted by individual or groups of automobiles being driven over any known driving sequence.

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 ...

Diesel Engine Exhaust Emissions
2010The direct release of exhaust gas components from combustion processes into the environment, i.e. emission, is the primary and most important process in the chain of emission, transmission, pollutant input and impact. Naturally, a basic distinction is made between emissions from vegetation, oceans, volcanic activity or biomass decomposition for ...

Onboard Locomotive Exhaust Emissions Measurement
ASME 2007 Rail Transportation Division Fall Technical Conference, 2007Limiting harmful locomotive exhaust emissions is important to the Nation’s health and safety. The Environmental Protection Agency (EPA) has comprehensive gaseous exhaust emissions (or referred to as emissions hereto) testing requirements in place. All current tests are conducted on stationary locomotives.

A New Exhaust Emissions Concept
SAE Technical Paper Series, 1988<div class="htmlview paragraph">This report deals with a new exhaust emission concept, the idea of which is the reduction of raw exhaust emissions and improvement of fuel economy by operating a gasoline engine in its (HC+NO<sub>x</sub>)-minimum. This is accomplished with a smooth running control. Further components of this concept are
