ABSTRACT:
An evaporation gas intercepting system prevents the entrance of an evaporation gas leaked from a canister into a passenger compartment of a vehicle with an air conditioning system in which an outside air intake or inside air circulation is selected. An engine control unit calculates a fuel injection quantity on the basis of parameters indicating the operating condition of an engine and correction coefficients, and a feedback correction quantity for correcting the fuel injection quantity on the basis of the output signal of an air-fuel ratio detector (oxygen sensor). If an excessive quantity of the evaporation gas is supplied to the engine such that the fuel injection quantity cannot properly be corrected by the feedback correction quantity, and the engine control unit carries out an evaporation correcting operation by using an evaporation correction, an air conditioning system control unit sets the automotive air conditioning system forcibly for an inside air circulation mode to prevent the entrance of the evaporation gas bearing a fuel odor and leaked from the canister into the passenger compartment.
