摘要： PROBLEM TO BE SOLVED: To determine the proper catalyst typical temperature corresponding to a deterioration state of a catalyst, in a catalyst typical temperature acquiring device of an internal combustion engine.
SOLUTION: The catalyst 40 for purifying exhaust gas is arranged in an exhaust passage of the internal combustion engine. The inside of the catalyst 40 is divided into a plurality of parts up to the downstream side from the upstream side. Temperatures of respective parts are determined, and the temperature of any part is set as a representative temperature. When the catalyst 40 is not deteriorated, since a catalytic reaction mainly occurs in an upstream side part, the temperature of the upstream side part is set as the representative temperature. As the catalyst 40 deteriorates, a part of mainly causing the catalytic reaction shifts to the downstream side. Considering this phenomenon, the temperature of a part nearer to an outlet is set as the representative temperature as the deterioration in the catalyst 40 advances.

摘要： PROBLEM TO BE SOLVED: To provide an air/fuel ratio control device for an internal combustion engine which appropriately executes correction of a basic fuel injection quantity even at the time of purge and properly compensates an error in the basic fuel injection quantity. SOLUTION: In the air/fuel ratio control device, a purge fuel quantity Fprg (a value greater than 0 at the time of purge, and 0 at the time of non-purge) is taken into account, and an injection quantity Fbaset in which an injection command should be issued to set an air/fuel ratio to a target air/fuel ratio is acquired in accordance with the formula of Fbaset=(Fi+Fprg)*(abyfs/abyfr)-Fprg (wherein Fi is a command fuel injection quantity, abyfs is detected an air/fuel ratio and abyfr is a target air/fuel ratio). The basic fuel injection quantity correction coefficient KF is acquired on the basis of the Fbaset. The basic fuel injection quantity is corrected by multiplying the basic fuel injection quantity Fbaseb before correction by the KF. Thus, the device can calculate the Fbaset to be an appropriate value in which an injection command should be issued to set the air/fuel ratio to the target air/fuel ratio abyfr and executes an appropriate correction of the basic fuel injection quantity regardless of under purging or non-purging.

摘要翻译：要解决的问题：提供即使在清洗时适当地执行基本燃料喷射量的校正的用于内燃机的空燃比控制装置，并适当地补偿基本燃料喷射量的误差。解决方案：在空/燃比控制装置中，考虑清洗燃料量Fprg（清洗时大于0的值，在非清洗时为0），并且注入量根据Fbaset =（Fi + Fprg）*（abyfs / abyfr）-Fprg的公式（其中，Fi是Fbaset =（Fi + Fprg）*（abyfs / abyfr）-Fprg）获得其中应当发出喷射命令以将空气/燃料比设定为目标空气/燃料比的Fbaset 指示燃料喷射量，检测到空气/燃料比的abyfs，而abyfr是目标空燃比）。基于Fbaset获取基本燃料喷射量校正系数KF。通过将校正前的基本燃料喷射量Fbaseb乘以KF来校正基本燃料喷射量。因此，设备可以将Fbaset计算为适当的值，其中应该发出喷射命令以将空燃比设定为目标空气/燃料比abyfr，并且执行基本燃料喷射量的适当校正，而不管下述清洗或不清洗。版权所有（C）2008，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide an air-fuel ratio control device for an internal combustion engine capable of enhancing determination accuracy in "sticking determination" of an air-fuel ratio feedback correction value to a guard value. SOLUTION: In this air-fuel ratio control device, a feedback correction value is obtained based on each output value of air-fuel ratio sensors disposed upstream and downstream of a catalyst, respectively, and air-fuel ratio feedback control is performed using a value DFi obtained by guard processing this value within a predetermined range. "DFi sticking" is determined in the case a value DFilow obtained by low pass filter processing a guard processed feedback correction value DFi is maintained to the guard value over a predetermined amount of time, and air-fuel ratio feedback control is stopped. As such, because "sticking determination" is performed using the value DFilow in which fluctuation is suppressed by the low pass filter processing, occurrence of the "DFi sticking" not being determined due to abnormality in an air-fuel ratio control system can be suppressed in the case where "DFi sticking" should be determined.

摘要翻译：要解决的问题：提供一种能够将空燃比反馈校正值的“确定”确定为保护值的内燃机的空燃比控制装置。解决方案：在该空燃比控制装置中，分别基于设置在催化剂上游和下游的空燃比传感器的每个输出值获得反馈校正值，并且执行空燃比反馈控制使用通过在预定范围内对该值进行保护处理而获得的值DFi。在通过低通滤波处理将防护处理反馈校正值DFi获得的值DFilow在预定时间量内保持为保护值的情况下，确定“DFi sticking”，并且停止空燃比反馈控制。因此，由于通过低通滤波处理抑制波动的值DFilow进行“粘附判定”，所以能够抑制由于空燃比控制系统的异常而不能确定的“DFi”的发生在确定“DFi贴”的情况下。版权所有（C）2008，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a fuel injection control device for an internal combustion engine, quickly setting the amount of oxygen storage in a catalyst to be proper when resetting stopped fuel injection while more effectively preventing the worsening of driveability.
SOLUTION: The fuel injection control device stops fuel injection from an injector 39 if an engine revolution speed Ne is higher than an injection stopping revolution speed NEFCth when a throttle valve opening TA is zero. The device resets the fuel injection so that the air-fuel ratio of the engine is richer than a theoretical air-fuel ratio when the throttle valve opening TA is zero or greater during stopping fuel injection (forcible reset), and resets fuel injection so that the air-fuel ratio is the theoretical air-fuel ratio when the revolution speed NE is lower than an injection resetting revolution speed NEREth (natural reset at a time t4) as the valve opening TA remains zero during stopping fuel injection.

摘要： PROBLEM TO BE SOLVED: To release almost all the oxygen adsorbed in a three-way catalyst device by an O
2 storage capacity by enriching control immediately after fuel cut in an air-fuel ratio control device of an internal combustion engine controlling a combustion air-fuel ratio to a desired air-fuel ratio according to the output of an air-fuel ratio sensor on the upstream side of the three-way catalyst device.
SOLUTION: The output of the air-fuel ratio sensor on the upstream side of the three-way catalyst device is corrected by a differential term due to a variation in output of an oxygen sensor on the downstream side of the three-way catalyst device. The correction of the output of the air-fuel ratio sensor by a differential term is prohibited or suppressed (step 102) until the oxygen adsorbed into the three-way catalyst device by the O
2 storage capacity is determined to be almost all released by the enriching control immediately after the fuel cut (step 105).
