摘要：PURPOSE:To cure adequate amount of purge by tting upper and lower limits of purge amount by adjusting negative pressure for the purge and by arranging a control means for increasing or decreasing the purge amount in proportion to air-fuel ratio compensation amount. CONSTITUTION:Venturi negative pressure Pv is either communicated or isolated by a solenoid valve 7 the opening of which is adjusted by a controller 6. By throttling the Venturi Pv, the amount of purge is adjusted. Here, the controller 6 also rves as a means for controlling air-fuel ratio in proportion to engine condition ES and ts upper and lower limits of the purge amount to increa the purge amount up to the upper limit when air-fuel ratio compensation amount is within normal control range and decrea the purge amount down to the lower limit when the said amount is outside the said range. This makes it possible to cure more purge amount than in proportion to the intake air during air-fuel ratio control without giving adver effect on the engine.
