摘要： PROBLEM TO BE SOLVED: To detect any leakage of evaporative systems with high accuracy even when a very large amount of fuel remains. SOLUTION: The time required for the pressure in evaporative systems 6, 7, 8, 10 and 11 to drop from a first predetermined pressure P0 to a second predetermined pressure P1 is measured for a state in which a reference orifice 17 as a reference leak hole is included in a leaking part and a state in which no reference orifice is included, respectively. By comparing the required time T2 in the state in which no reference orifice is included with a reference determination time of the required time T1 in the state in which the reference orifice is included, multiplied by a predetermined coefficient, a state of leakage is diagnosed without being affected by the atmospheric temperature or the like. The pressure drop state is adequately indicated even when a very large amount of fuel remains by using the time from the first predetermined pressure P0 to the second predetermined pressure P1 as an index of the pressure drop state.

摘要： PROBLEM TO BE SOLVED: To provide a fuel vapor leakage inspection apparatus in which a fuel vapor is prevented from flowing into the atmosphere during a leakage inspection by stopping the leakage inspection when the adsorbing capacity of an adsorbent is lowered. SOLUTION: When the leakage inspection is performed for a fuel vapor treatment system, a discharged fuel vapor concentration calculated by an ECU 30 beforehand according to a signal detected by an air-fuel ratio sensor 22 is read out. The ECU 30 calculates the concentration of the discharged fuel vapor discharged from a canister 50 into an intake pipe 12 based on the air-fuel ratio of exhaust gases detected by the air-fuel ratio sensor 22 and a theoretical air-fuel ratio. The adsorbed amount of the fuel vapor adsorbed by the adsorbent 52 in the canister 50 is calculated based on the concentration of the discharged fuel vapor. When the calculated adsorbed amount of fuel vapor is larger than a predetermined amount, if fuel supply into a fuel tank is detected, it is determined that a large amount of fuel vapor is adsorbed to the adsorbent 52 and the adsorbing capacity of the adsorbent 52 is lowered. Then, the leakage inspection is stopped. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide an evaporated fuel treatment device reducing difference between actual air fuel ratio and target air fuel ratio caused by purge of evaporated fuel.
SOLUTION: CPU 52 measures actual air fuel ratio λ1 from detection signal of an air fuel ratio sensor 26. If difference Δλ=/λ1-λ0/ between the target air fuel ratio λ0 and the actual air fuel ratio λ1 is larger than a predetermined range Δλ0, the CPU 52 judges that evaporated fuel quantity purged to an intake air passage 14 is deviated from a target value and that a cause thereof is that the value of reference flow rate Q100 of a purge valve 36 is not correct. The CPU 52 calculates actual reference flow rate Q100 from measured actual air fuel ratio λ1 and rewrites the value of the reference flow rate Q100 corresponding to present intake pressure P0 indicated on a characteristic map by the value of the calculated reference flow rate Q100.

摘要： PROBLEM TO BE SOLVED: To provide a vaporized fuel leak inspecting device that stops leak inspection when adsorption ability of adsorbent is deteriorated for preventing vaporized fuel from flowing into atmospheric air during leak inspection. SOLUTION: In executing leak inspection in a vaporized fuel processing system, concentration of discharged vaporized fuel preliminarily determined by an ECU 30 based on a detection signal of an air-fuel ratio sensor 22 is read. The ECU 30 determines the concentration of discharged vaporized fuel discharged from a canister 50 into an intake tube 12 based on deviation between an air-fuel ratio in exhaust gas detected by the air-fuel ratio sensor 22 and a theoretical air-fuel ratio. Adsorption quantity of vaporized fuel adsorbed in the adsorbent 52 in the canister 50 can be determined based on the concentration of discharged vaporized fuel. In a case where adsorption quantity of vaporized fuel determined is larger than prescribed quantity, it is determined that a mass quantity of vaporized fuel is held adsorbed in the adsorbent 52, and that the adsorption ability of the adsorbent 52 is deteriorated, and leak inspection is stopped.
