摘要： PROBLEM TO BE SOLVED: To carry out a good fuel vapor treatment with a simple constitution without using a HC concentration sensor for monitoring a concentration of a purge fuel vapor (purge gas) in heater heating thermostat control. SOLUTION: When the fuel vapor released from a fuel tank 20 and adsorbed and retained on a fuel adsorption layer 35 (35a, 35b) in a canister 30 is purge- controlled by ON/OFF control of a purge valve 23, a heater plate built in the canister 30 is ON/OFF controlled based on a concentration of the purge fuel vapor presumed and calculated accompanying with an air/fuel ratio control of the internal combustion engine. Thereby, a sensor for detecting the concentration of the purge fuel vapor fed out to an intake passage 2 of the internal combustion engine from the canister 30 through purge passages 22, 24 is not required, and thus allowing a good fuel vapor treatment with a simple constitution.

摘要： PROBLEM TO BE SOLVED: To accurately estimate the concentration of an evaporated fuel at a fuel injection valve.
SOLUTION: A transportation time required for the evaporated fuel passing through a purge valve 17 immediately after the purge valve 17 is opened to reach the fuel injection valve after the purge valve 17 is opened is calculated. The concentration of the evaporated fuel at the fuel injection valve after the transportation time is elapsed is calculated based on a time lag curve of first order specified by the maximum varied amount of the concentration of the evaporated fuel and a time constant. The disturbance of air-fuel ratio when purge treatment is started can be suppressed by setting the corrected amount of fuel injection amount according to the concentration of the evaporated fuel at the fuel injection valve 6.

摘要： PROBLEM TO BE SOLVED: To surely prevent fuel vapor from leaking to the outside, even when a suction pump provided for purge is broken, in a fuel vapor treating device including a canister. SOLUTION: A double acting type diaphragm pump 1 is constituted by making space on both sides of a diaphragm 21 provided in a pump body 10 as pump chamber 22 and 23. An electromagnetic type reciprocating driving part 33 is provided in a housing 34 formed integrally with the pump body 10. Because the driving part 33 is integrally incorporated into the pump 1 and the whole of the pump 1 is sealed, different from an electric pump, there is no possibility that fuel vapor leaks to the outside, even if the diaphragm 21 is broken. Even if fuel vapor leaks at the inside and enters the driving part 33, spark is not generated in the electromagnetic driving part 33 and thereby there is no possibility of an explosion. As the pump 1 is the double acting type, the pump 1 produces large discharging amount, even if the pump 1 is a small type.
