Automobile Emission Control

Automobile emission control systems are the systems that reduce vehicle emissions that cause air pollution. When the automobile was first invented, there were no automobile emission control regulations. However, increasing concerns about the environment prompted lawmakers to develop emissions regulations for personal and commercial vehicles. These systems can reduce a number of emissions and help to keep the environment safer for everyone living and breathing the air around them.

Tailpipe emissions

Automobile emission control systems exist to eliminate several kinds of emissions, but the most common emissions that people are aware of are the emissions that come from the tailpipe. Emissions are the result of fuel consmption in the engine and come in several forms. Hydrocarbon emissions are built of fuel that either hasn’t been burned or wasn’t burned by the engine all the way. Hyrocarbons are toxic and can lead to the formation of fog. These emissions are also directed linked to liver damage and several types of cancer. Nitrogen oxides are produced when the oxygen from the vehicle reacts with nitrogen from the air at high temperatures. Nitrogen oxides contribute mostly to environmental hazards such as smog and acid rain.

One of the most worrisome vehicle emissions is carbon dioxide. While carbon dioxide is not toxic to humans, it contributes to global warming. Carbon monoxide is another vehicle emission that actually is toxic to humans. Formed from incomplete combustion, carbon monoxide is especially dangerous for people with heart disease because it cuts down the blood’s ability to carry oxygen to the lungs and throughout the body. Sulfur oxide and particulates are also types of tailpipe emissions. Sulphur oxide can come from unrefined oil, while particulates are very small particles of debris that can be expelled from the tailpipe. Automobile emission control systems can help you reduce these emissions.

Automobile emission control function

Automobile emission control systems function in three major ways. One is that they increase engine efficiency. Increasing engine efficiency can reduce the amount of emissions released from a vehicle. Increasing vehicle efficiency is also a task of automobile emission control systems. Finally, automobile emission control systems act to clean emissions so that they are not as harmful to the environment. Engine efficiency can be increased by using fuel injection systems and electronic controls. Vehicle efficiency can be improved with better vehicle design that minimizes air resistance and improves the efficiency of the powertrain. Automobile emission control systems also reduce the amount of pollutants that are released.

Emission testing

Because automobile emission control is such an important concern, emission testing is required for personal and commercial vehicles in many states. Some individual counties require emission testing while states do not. Emission testing is usually completed along with a vehicle's reqired safety inspection and must be done by a qualified mechanic. When a mechanic is inspecting your emissions, emissions from your vehicle are measured in parts per million and must not exceed established guidelines. If your car or truck does not pass emissions testing, you may be required to have the vehicle repaired so that it does not emit emissions above the guidelines. These repairs may include repairs to the automobile emission control systems in your car or installation of new car parts.
