Facts about harmful gas emissions caused by automobiles

Various harmful gases are emitted on US roads on a daily basis. Due to the fact that thousands of Americans drive their vehicles every day, the cumulative effect is rather large. Today 1ST Auto Service, of Auburn, WA has decided to give you a bit more information about this global issue, so you can either take some auto repair precautions or make better decisions when purchasing a car in the future.

Main types of harmful emissions

1. Engine exhaust emissions – Contemporary combustion engine exhaust produces carbon monoxide and hydrocarbons (known as volatile organic compounds) which can cause breathing or sight problems. According to a research, conducted by the Environmental Protection Agency, they are carcinogenic. Exhaust emissions also contain carbon dioxide which is thought by the same agency to contribute to our major global warming problem.
2. Evaporative emissions – Summer is the season when warmth provokes even higher gasoline evaporation from your vehicle. Even after you turn the car off when you are not driving, your hot engine will continue to emit gas vapors until it cools down. Another case when a lot of vapors are emitted, is when you fill your car’s tank with gas. The new liquid gas you pour displaces even more gas vapors that have built up in your tank, forcing them out into the environment.

Car repair and diagnosticsVisiting your car repair shop for regular check-ups, however, will not stop the process but can at least reduce the level of harmful emissions. Luckily, the 1990 Clean Air Act mandates that all auto manufacturers have an on-board diagnostics computer for emission testing. This means all car models manufactured after 1996 have an OBD computer which can evaluate your tailpipe emissions. This can help you determine when the time for a visit to an auto repair shop has come. and serves as a warning sign before your problems become serious and expensive. Of course, getting a car repair is not all you can do to reduce your emissions and help the environment. You can reduce the use of air conditioning and heat to only when it’s absolutely necessary. In addition to this, you can shut your engine off when you have to wait before crossing and restarting it again when the time comes. This bears a lower emissions cost than allowing it to sit idle.
