Cars and trucks emit carbon dioxide and other greenhouse gases, which contribute one-fifth of the United States’ total global warming pollution. Greenhouse gases trap heat in the atmosphere, which causes worldwide temperatures to rise.
How does the fuel system works in an automobile?
A gasoline car typically uses a spark-ignited internal combustion engine, rather than the compression-ignited systems used in diesel vehicles. In a spark-ignited system, the fuel is injected into the combustion chamber and combined with air. The air/fuel mixture is ignited by a spark from the spark plug.
What are the components of emission control system?
The components of the emission control system include fuel fill cap, vapor recirculation tube, fuel tank vapor control valve, evaporative emission canister, fuel tank pressure sensor, canister vent valve, evaporative two-way valve, and the evaporative canister purge valve.
