Title:
燃料蒸気処理装置及び排気ガス浄化装置
Document Type and Number:
Japanese Patent JP3596671
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a fuel vapor processor and an exhaust emission control device which do not exert a bad influence upon an air fuel ratio set previously, the operation characteristics of an internal combustion engine and the components of exhaust emission and can also improve fuel economy and realize high NOx reduction and purification efficiency under discharge temperature conditions. SOLUTION: The fuel vapor processor is provided with the canister 2 connected to a fuel tank 1, a steam blower 6 for supplying steam to the canister 2 and a reformer 7 for reforming the desorption gas purged from the canister 2. The reformer 7 is connected to an intake pipe 4 through a purge control valve 3. Although the desorption gas includes fuel vapor and steam, it is introduced in the reformer 7 for performing steam reforming reaction to obtain reformed gas including hydrogen and carbon monoxide. This reformed gas is sent to the intake pipe 4 for combustion. Fuel vapor is thus utilized effectively.
