摘要： PROBLEM TO BE SOLVED: To detect purge air amount without using an exclusive air flow meter, regarding an evaporated fuel processing device for processing evaporated fuel generated within a fuel tank by purging. SOLUTION: This device is provided with a canister for adsorbing fuel vapor generated within the fuel tank and a purge control valve arranged between the canister and an intake passage. Flow rate QPG of purge gas flowing in the purge control valve is determined (step 192 and 194). A fuel injection quantity correction coefficient FGPG is determined to prevent an air-fuel ratio deviation caused by purge gas. Based on the fuel injection quantity correction coefficient FGPG, a fresh air ratio PGFRSH showing the ratio of purge air in purge gas is determined (step 196). Based on purge gas flow rate QPG and the fresh air-ratio PGFRSH, purge air amount QPG×PGFRSH is determined. The value is integrated to determine integrated purge air amount SUMQPG (step 198).

摘要： PROBLEM TO BE SOLVED: To provide an operation control device with a control mechanism for changing a valve opening/closing timing for an intake valve or an exhaust valve and a valve opening amount thereof, thus surely suppressing the occurrence of torque shock. SOLUTION: The operation control device comprises: a transmission for controlling a gear ratio; the intake valve control mechanism for controlling the valve opening/closing timing for the intake valve and the valve opening amount thereof; and an intake amount control mechanism provided separately from the intake valve control mechanism for controlling the amount of intake air into a combustion chamber. When a speed of changing the valve opening amount of the intake valve or a speed of changing the valve opening/closing timing with the intake valve control mechanism gives less influences on the operating property of the intake valve control mechanism, the valve opening/closing timing for the intake valve or the valve opening amount thereof is changed with the intake valve control mechanism to suppress the occurrence of torque shock due to the change of the gear ratio when changing the gear ratio with the transmission. When it gives greater influences thereon, the amount of intake air into the combustion chamber is changed with the intake amount control mechanism to suppress the occurrence of torque shock due to the change of the gear ratio when changing the gear ratio with the transmission.

摘要： PROBLEM TO BE SOLVED: To prevent the concentration of fuel in purge gas from being erroneously learned in such a state that the state of fuel adhered to wall surface is instable in an air/fuel ratio control device of an internal combustion engine. SOLUTION: A learned value is updated when the deviation of a feedback correction factor to a reference value exceeds a predetermined dead zone. As a parameter related to the stability of the state of fuel adhered to wall surface of an intake passage, a deviation ΔWP of a smooth value WP to a basic adherence ratio WPBS (steps S100 to S110)is acquired. When the deviation ΔWP exceeds a predetermined range with zero taken as its center, the upper limit value KAFFH or the lower limit value KAFFL of the dead zone is increased (step S112).

摘要： PROBLEM TO BE SOLVED: To always excellently maintain control accuracy of the air-fuel ratio while purging a large quantity of evaporated fuel from before starting feedback control using an air-fuel ratio sensor and an oxygen sensor in an evaporated fuel processing system of an internal combustion engine. SOLUTION: A canister is arranged for storing the evaporated fuel supplied to an intake passage of the internal combustion engine.

An increasing-decreasing correction is applied to the ISC flow rate by using the KQNE (Step 118). COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide an ideal startability to an internal combustion engine in an evaporated fuel processing device for feeding an evaporated fuel to each of cylinders at engine start. SOLUTION: A canister for accumulating the evaporated fuel is allowed to communicate with the intake port of each of the cylinders, and a purge control valve is installed for each cylinder. Immediately after the starting of the internal combustion engine, the purge control valves of all cylinders are opened to perform a purge in nonsynchronous with a crank angle (in Fig. (C)). At a time when a cylinder discriminating signal is generated, nonsynchronous purge gas not sucked remains in intake ports (#4, #2, #1 in Fig.). Furthermore, correction purge is performed by opening the purge control valves for the cylinders (#2 and #1 in Fig.) in which a time of generation of the cylinder discriminating signal and start of the post-intake stroke exceeds a determination value (open arrows 50, 52).
