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.

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.

<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.

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.
