What is the evaporative emissions control system?

Gasoline evaporates, even in the gas tank of your Accord. If those fumes are allowed to escape into the atmosphere, they create hydrocarbons that damage the environment and also contribute to smog/air pollution. To help combat this problem, your car uses an evaporative emissions control system. Basically, there’s a charcoal canister in the fuel system that absorbs fuel vapor. If you’re not driving, it just stores the vapors. Once you start driving, the vapors are sent to the engine where they’re burned (also increasing fuel mileage).
