Exhaust Systems

Exhaust Systems The exhaust system on a car is the most important device to keep our environment clean. Many exhaust emissions from the engine such as water, oxygen, nitrogen, and carbon dioxide, are of little concern. Others, such as hydrocarbons (HC), oxides of nitrogen (NO ), and carbon monoxide (CO), can cause environmental and health problems if not controlled. Hydrocarbon emissions react with sunlight, which cause photochemical smog. The exhaust system controls these the best possible …

…carbon monoxide are probably the most dangerous. Hydrocarbons react with the sun and cause smog, which is a very big environmental hazard. Carbon Monoxide poisoning caused 700 death's in 1993. Engineers are developing new ways of keeping the air clean. Soon in the future a new kind of car will be driven, a car that is environmentally friendly. If this happens I will probably be a bit disappointed because nothing beats the sound of a combustible engine.
