EVAPORATIVE FUEL CONTROL APPARATUS OF INTERNAL COMBUSTION ENGINE

PROBLEM TO BE SOLVED: To provide an evaporative fuel control apparatus which has a simplified structure, thereby achieving reduction in the number of assembly steps and which causes evaporative fuel to be combusted reliably and efficiently.SOLUTION: In the evaporative fuel control apparatus 10, a first passage 48 of a bypass conduit 40 is connected between an upstream side of an intake passage 24b and a switching valve 42, and second passages 50a to 50d interconnect the switching valve 42 and downstream sides of intake passages 24a to 24d, whereas a purge conduit 46 to which the evaporative fuel is supplied is connected to the switching valve 42. The switching valve 42 is operated responsive to a driven state of an internal combustion engine 12, thus switching between a communication state between the first passage 48 and the second passages 50a to 50d, and a communication state between the purge conduit 46 and the second passages 50a to 50d, such that intake air or the evaporative fuel is made to flow to the intake passages 24a to 24d.
