Carbon Canisters and the Evaporative Emission Level Tendency in Brazil for Passenger Cars 2015-36-0319

Carbon canisters are used in gasoline passenger vehicle and light duty truck applications. The component is part of the vehicle emission control system. Activated carbon (also known as charcoal) traps hydrocarbon vapors from the fuel tank and vapors created during the fuel tank refueling and venting events.Canister design, charcoal type and performance have been driven by evaporative emission regulations around the world, and evaporative emission requirements have enhanced through the years. The trend of evaporative emission requirements in Brazil indicates the use of improved carbon canisters in the near future.Carbon canisters are needed to store hydrocarbons that would otherwise pollute the environment. Wood based activated carbon is manufactured from sawdust, which is a renewable resource. The result is a healthier earth on which we live. Figure 1 illustrates the activation process of carbon.Figure 1Activation process of carbon.
