摘要： PROBLEM TO BE SOLVED: To provide a rotation speed control device for an internal combustion engine favorably controlling the rotation speed, even if performing a feedback control of the rotation speed of the internal combustion engine in a condition directly connected to a driving wheel. SOLUTION: In a driving system of a hybrid vehicle, a crankshaft 10a of the internal combustion engine 10 is directly connected to the driving wheel 15 via a power division mechanism 13. An ECU 16 performs the feedback control of the rotation speed by regulating the throttle opening using a feedback correction term eqi calculated according to a deviation between the actual rotation speed ene and the target rotation speed entcal of the internal combustion engine 10. Wherein the ECU 16 finds feedback correction terms eqi1-eqi3 for every three operation regions divided according to the car speed so as to control the rotation speed using the feedback correction term in the operation region corresponding to the car speed at that time.

摘要： PROBLEM TO BE SOLVED: To accurately correct deviation of an air-fuel ratio which may be caused by variation of vapor and fuel density accompanied with fuel temperature fluctuation, without the use of a fuel temperature sensor. SOLUTION: Fuel temperature is estimated from cooling water temperature and intake temperature (step 104). Afterward, an air-fuel ratio correction factor is calculated from a preset map, based on the estimated fuel temperature and intake pipe pressure (step 105). The map is so set that the higher the estimated fuel temperature is, the larger the air-fuel ratio correction factor is, and the more increased fuel injection time is. In addition, an invalid injection time TV is corrected according to the estimated fuel temperature (step 108). Then fuel injection time TI is calculated by the following equation: TI=TP×TP total + TV, where TP denotes reference injection time, Ftotal denotes total correction factors including the air-fuel correction factor, and TV denotes the invalid injection time (step 109).

摘要： PROBLEM TO BE SOLVED: To increase the accuracy of air-fuel ratio control at the time of a high temperature when vapors are easily generated. SOLUTION: Even at the time of a high engine room temperature when vapors are easily generated in a fuel pipe, air-fuel ratio learning itself is not prohibited, only the backup of a learning value KG in a backup RAM is prohibited to prevent the renewal of a learning backup value KGB. Accordingly, erroneous learning is prevented. Also, even at the time of a high engineroom temperature, air-fuel ratio learning is continued and a learning value KGB thereof is reflected on air-fuel ratio control, and thus a feedback correction coefficient FAF takes a value approximated to '1.0' Thus, even if air-fuel feedback control is stopped by fuel cut or the like and the feedback correction coefficient FAF is reset to an initial value 1.0, a difference between the initial value and the proper value of the feedback correction coefficient FAF is much smaller than that of the conventional case, and the deviation of an air-fuel ratio A/F after the resumption of the air-fuel ratio feedback control is reduced.

摘要： PROBLEM TO BE SOLVED: To always detect misfires occurring in an internal combustion engine with high accuracy irrespective of the running condition of the engine. SOLUTION: In the misfire detector of an internal combustion engine, a crank angular speed fluctuation amount is usually calculated for each cylinder based on a rotational angle signal NE corresponding to the rotation of a crankshaft and the occurrence of misfires in the engine is detected by comparing the calculated cylinder crank angular speed fluctuation amount with a specified misfire determination value. Here, under the condition that the engine is normally ignited, an inter-cylinder crank angle difference is calculated by an electronic controller 9 and the calculated crank angle difference is learned for each cylinder of the engine and each running condition. On the other hand, in the electronic controller 9, a crank angular speed is calculated for each cylinder by correcting the crank angle difference based on learned values regarding each corresponding cylinder and each running condition of the engine and crank angular speed fluctuation amount for each cylinder compared with the misfire determination value is calculated based on changes in the obtained crank angular speed.
