Advances in Automobile Emission Control Techniques

Often times these more stringent standards are put in place by the EPA as federal standards after research and testing has been accomplished by those states. An example of this is the required use of Catalytic converters on pollution controlled motor vehicles in 1974 in California, two years later in 1976, the EPA required the use of Catalytic converters on all pollution controlled motor vehicles nationwide.

The regulatory measures target the emissions from industries as well as the products resulting from certain industries. The agency establishes certain regulations that seek to standardize the emissions in terms of quantity and if companies are found

Water is a polar molecule so it will not mix with gasoline because only molecules of the same polar bonds will mix. 4. When you’re hot you sweat to cool off. When you release sweat it absorbs the heat from your body and cools you off.

There are two main types of air pollution, particulate matter (PM) and ozone. Particulate matter is some tiny dust. For example, according to a beam of light at night there are countless dusts floating in the air. They are particle. Ozone is an invisible chemical gas in the air. When these gas touch with light will become smog. Factory and vehicles exhaust emissions have become the largest cause of PM and ozone pollution in the United States. If a plant wants to run, they need to burn fuel to provide power; however, a lot of particulate matter will float in the air when the factory burns fuel. When people drive cars can

The burning of gasoline by automobiles releases carbon dioxide and other types of air pollution

Your car has a gas cap to seal off its fuel system and maintain proper levels of pressure in the fuel tank itself. A gas cap also keeps hydrocarbons from being burned off into the atmosphere when you aren’t actually driving. Luckily, if this is why

regulation, in the United States, stemmed from the Clean Air Act of 1970. The act instituted the first federal standards for air quality and enabled these standards to be enforced. It also authorized federal and state regulations to limit emissions from stationary, or industrial, sources and mobile sources like automobiles. Specifically, its goal for automobiles was to reduce pollution and health problems caused by vehicles and by gasoline use. Catalytic converters, which convert would-be toxic emissions into less harmful gasses, became a required component in new vehicles in 1976. Leaded gasoline was phased out because vehicles with the converter could not operate on it, and this also eliminated the public health concern caused by lead. By

I would demand for the regulatory and reporting standards under National Emission Standards for Hazardous Air Pollutants (NESHAPs).

Old cars have carburetors, a small rotating plate that allows air and fuel through a small pipe and into the car motor. If the carburetor got cold, it would not work the way it should. That will change the ratio

Your vehicle requires plenty of clean fuel to run. Contaminated fuel will eventually become clog up your fuel injectors. When this happens, your vehicle engine may not get the proper amount of fuel at the correct pressure to run at peak performance. This hurts performance as you drive around the Reno and Sparks area. One of the causes of the buildup of harmful deposits on valves and in the combustion chamber is contaminated fuel.

After gasoline is refined, some chemicals are added. Some of the chemicals that are added are anti-knock compounds. Usually these compounds react quickly to the chemicals in the gasoline that burn quickly so that it could prevent “engine knock”. After this other additives are added to prevent the formation of a gum type of congestion in the engine. The gum is more of a resin that is formed in gasoline that can coat the internal parts of the engine and increase wear.

Pollutants that are given off through the emissions of automobiles are hydrocarbons, nitrogen oxides, carbon monoxides, and carbon dioxides. Hydrocarbons emitted by automobiles create smog. Smog can create health problems for people. These problems include lung and respiratory problems. Nitrogen oxides form acid rain that hurts plants, wildlife, and the paint on our cars. Carbon monoxide reduces the flow of oxygen in the bloodstream. Carbon dioxide is a "greenhouse gas" and is a primary factor contributing to global warming.

And the production process and process operation can also release certain sulfur dioxide. In daily life, the automobile exhaust also contain certain sulfur dioxide. With the popularization of automobile, the automobile exhaust has been one of main pollution sources for the environment.

Other pollutant from cars was lead; it is highly toxic metal. Lead has been phased out of gasoline, but there, are other sources of it. It includes paints, production of lead batteries, water pipes, and a few heir dye products. Car exhausts can also produce nitrogen oxide, volatile organic compounds, which are also, product of burning fuels. Factories and power plants produce same pollutants as cars do, but they produce them in bigger mnozstve and the produce some more such as sulfur dioxide, which is made during production of paper, burning coal in power plants, or smelting of metal. Burning other fuels like wood, or natural gas can make all of these pollutants too.

During loading of oil tankers, Volatile Organic Compounds (VOC) are emitted to the atmosphere together with the inert gas from the upstream pipe lines and the cargo tanks where vapour balancing doesn’t exist. The cargo tank atmosphere initially contains nitrogen, CO2, other non methane compounds, and possibly VOC from previous cargo, but during loading hydrocarbon gases (methane-pentane and heavier components) are released from the cargo. VOC is generated by the flashing of the cargo in the piping system from the source to the cargo tanks, and from the evaporation of VOC from the oil surface inside the cargo oil tanks. The reasons for reducing VOC emissions are twofold: environmental protection and cost reduction by minimizing product losses.
