发明名称 Evaporative fuel control apparatus for internal combustion engine
摘要 In an 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 respective intake passages (24a to 24d), whereas a purge conduit (46) to which the evaporative fuel is supplied is connected with respect to the switching valve (42). The switching valve (42) is operated responsive to a driven state of the 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 evaporative fuel is made to flow to the intake passages (24a to 24d).
