摘要： When a diagnosis execution condition is established, a canister closure valve is closed, thereafter, a purge control valve is opened, a purge control valve is closed in a state where negative pressure is introduced into an evaporated gas system to thereby maintain the evaporated gas system in a hermetically-sealed state and the hermetically-sealed state is continued until abnormality diagnosis is finished. Time period for maintaining the evaporated gas system in the hermetically-sealed state is divided into three time periods of a pressure change determining time period at a first time, an awaiting time period and a pressure change determining time period at a second time. After determining a pressure change amount DPT1 of the evaporated gas system in the pressure change determining time period at the first time, the evaporated gas system is successively maintained in the hermetically-sealed state, after the predetermined awaiting time period has elapsed, the pressure change determination at the second time is carried out by which a pressure change amount DPT2 of the evaporated gas system is determined. Further, presence or absence of leakage of the evaporated gas system is diagnosed by comparing the pressure change amount DPT1 at the first time with the pressure change amount DPT2 at the second time.

摘要： A leakage diagnosing apparatus for an evaporated gas purge system, which executes purge system leakage diagnosis based on a detected pressure change amount and an introduced pressure which is introduced into a part of the purge system including at least a fuel tank and a canister. The detected pressure change amount is obtained by detecting pressure in the part of the purge system after such part of the purge system is hermetically sealed. Accordingly, the reliability of the leakage diagnosis is improved because an erroneous diagnosis caused by the introduced pressure is prevented. The detected pressure change amount may be compensated based on the introduced pressure into the sealed gas purge system. Accordingly, an erroneous leakage determination is prevented, and the reliability of leakage determination is improved.

摘要： An air/fuel ratio controller for an internal combustion engine that obtains stabilized air-fuel ratio controllability even when an air-fuel ratio is changed during purge execution. In purge control to discharge fuel vapor adsorbed in a canister to an intake-air side of an internal combustion engine, the controller controls a purge ratio, by controlling operation of the purge solenoid valve, even when an air-fuel ratio is changed. A fuel-injection quantity from an injector is then compensated in correspondence thereto. Thus, stabilized air-fuel ratio controllability can be obtained by correction with a fuel-injection quantity, or purge correction by a control duty of the purge solenoid valve as a purge control parameter, even when an air-fuel ratio .lambda. is changed during purge execution, taking a predetermined ratio as the purge ratio.

摘要： A throttle opening range is divided into regions corresponding to the opening positions, and a deviation between an actual intake air suction state and a predetermined suction state provided for each of the divided regions is calculated. Intake system abnormality such as air cleaner clogging or intake pipe leakage is determined, if the deviation changes in a predetermined increasing or decreasing direction over a plurality of the divided regions. The air suction state may be represented by an intake pipe pressure or intake air flow quantity.

摘要： An evaporated fuel gas purging system performs breakdown analysis without deterioration of drivability and exhaust emission even when the amount of purged fuel gas is large. During introduction of negative pressure into the purge system, a control value DUTY sets opening of a purge control valve and a purge flow amount GPG is derived from a map based on differences in the control value DUTY, atmospheric pressure and intake pipe pressure. Thereafter, a purge ratio PGR is calculated from intake air GA and purge flow GPG (PGR=GPG/GA), and a fuel injection correction value FAFLEAK=PGR.times.(FGPGAV-1).times.K1 is calculated, with FGPGAV-1 being the air-fuel ratio feedback correction deviation per 1% purge ratio, and K1 being an error correction coefficient. Then, the fuel injection correction FAFLEAK is guard-processed to maintain it below an upper limit guard value KFLEAKMX.

摘要： An air-fuel ratio control apparatus of an internal combustion engine capable of learning and controlling an air-fuel ratio accurately both in idling and non-idling without being affected by concentration of evaporated fuel. Uniform deviation of an air-fuel ratio is detected before starting purging of the evaporated fuel (steps S133 to S137), air-fuel ratio learning values KGI.sub.0 to KGI.sub.7 and KGS.sub.0 to KGS.sub.7 are stored respectively so that the uniform deviation shows a predetermined value or lower both at idling time and at non-idling time (steps S138 to S142), and air-fuel learning values KG.sub.0 to KG.sub.7 in respective areas including idling are updated or renewed with a value obtained by leveling or averaging air-fuel ratio learning values KGI.sub.0 to KGI.sub.7 and KGS.sub.0 to KGS.sub.7 stored both at idling time and at non-idling time (step S145). Thereafter, purging of the evaporated fuel is started, and area learning of the air-fuel ratio is also executed by air-fuel ratio learning values KG.sub.0 to KG.sub.7 in respective areas.

摘要： An air-fuel ratio control apparatus for an internal combustion engine for learning and controlling an air-fuel ratio accurately even during execution of purging of evaporated fuel. The evaporated fuel generated in a fuel tank is adsorbed to a canister, and the adsorbed fuel is evaporated and purged together with air to the intake side of the internal combustion engine through a purge valve. During normal purge rate control by the purge valve, air-fuel ratio feedback values detected by an oxygen sensor are averaged, and the concentration of the evaporated fuel taken into the internal combustion engine through the purge valve is detected by the deviation from a stoichiometric air-fuel ratio 1 of the averaged value and the purge rate. Further, after the lapse of a predetermined period of time after purging is started, air-fuel ratio learning values are renewed in accordance with the air-fuel ratio feedback value and stored in a RAM.

摘要： When refueling is started, a purge valve is closed, and power is supplied to a coil of a solenoid so that a constant pressure operating valve of an atmospheric escape valve is opened. When the temperature of the fuel tank rises while an engine is at a stop, fuel evaporation gas generates and the pressure within the fuel tank increases. When the differential pressure between the in-tank pressure and the atmospheric pressure increases, a first communication passage is opened, and the pressure is released to the outside. Thus, the pressure within the fuel tank can be maintained at an appropriately high pressure level while the vehicle is at a stop, and the quantity of the fuel evaporation gas generating while the vehicle is at a stop can be controlled.
