ABSTRACT:
The present invention pertains to a method for producing a mixture including an injected engine fuel from an injector, a combustion engine intake-air and an evaporative gas from the engine fuel. The method includes the steps of measuring a characteristic of the evaporative gas and changing step for changing a mixing ratio of the evaporative gas to at least one of the injected engine fuel and the combustion engine intake-air, according to the measured characteristic of the evaporative gas, by changing a flow rate of the combustion engine intake-air.
