Abstract
PURPOSE: In a multicylinder multicarburetor engine, to ensure suction of a sufficient amount of purging air by selectively connecting only one carburetor related to a certain cylinder to a canister at an intake stroke.
CONSTITUTION: Now, when an engine 1 is started to generate a suction negative pressure in one carburetor 2A for example, associated check valve 20 only is opened so that a fuel caught by an adsorbent 8 inside a canistor 4 is sucked along with an air from an atomsphere intake opening 10 into a carburetor 2A through a main purge pipe 15, a distribution chamber 6, a branch purge pipe 16 before burned in a cylinder 1A of the engine 1. At this time, as no suction negative pressure is generated inside the other carburetor 2B due to a lapse of a combustion cycle timing, a check valve 21 is kept closed. Thereby, an air in the carburetor 2B cannot be sucked by a suction negative pressure in the carburetor 2A so that a sufficient amount of purging air from the atmosphere intake opening 10 may be surely fed into.
