ADSORPTION SYSTEM AND METHOD FOR IMPERFECT COMBUSTION GAS

摘要

PURPOSE: An adsorption system and a method for imperfect combustion gas are provided to effectively eliminate imperfect combustion gas by drawing in the imperfect combustion gas staying in an intake pipe into a canister when an electronic throttle valve shuts off an intake pipe, and drawing in the collected imperfect combustion gas through a canister when an electronic throttle valve shuts off an intake pipe when the electronic valve opens the intake pipe with a direction switching valve. CONSTITUTION: An adsorption system and method for imperfect combustion gas comprises a controller(110), an electric throttle valve(121), and a canister(130) and a direction switching valve(131). The controller controls a vehicle generally. The electric throttle valve opens and shuts an intake pipe(120) with the control of the controller. The canister collects imperfect combustion gas. The direction switching valve is connected to some part of the intake pipe. When the electronic throttle valve shuts off the intake pipe with the control of the controller, the direction switching valve draws in the imperfection combustion gas existing in the intake pipe into canister. When the electronic throttle valve opens the intake pipe, the direction switching valve draws in the explosion collected through the canister into the intake pipe.
