Three pollutants from motor vehicles are indicated as causing California's air pollution problems. These are hydrocarbons, oxides of nitrogen, and carbon monoxide. The sources of emissions from gasoline-powered vehicles are the exhaust, crankcase, carburetor, and fuel tank. Motor vehicle emission standards for exhaust hydrocarbons and carbon monoxide were established in 1959. A standard for crankcase emissions was added in 1960. Since that time crankcase as well as exhaust control devices have been installed on vehicles in California. Their installation is not expected to cause exhaust emissions of oxides of nitrogen to increase. Exhaust devices for hydrocarbon and carbon monoxide control are being installed on some 1966 model cars. It is anticipated that hydrocarbon control alone will reduce ozone concentration in the atmosphere. Control systems for oxides of nitrogen which can meet the standards have not been developed and it may be a number of years before they become available.
