摘要： PROBLEM TO BE SOLVED: To provide a controller of an internal combustion engine capable of suppressing deterioration of the exhaust emission in case a flow rate adjusting means to adjust the flow rate of EGR gas and a temperature adjusting means to adjust the temperature of EGR gas are arranged to be driven interlocking by a single actuator. SOLUTION: In a constitution in which an EGR valve 13 (flow rate adjusting means) and a selector valve 16 (temperature adjusting means) are driven interlocking by a single electric motor 131, driving the valve 16 is admitted on condition that it is in the fuel cut state. Driving the valve 16 is exceptionally admitted if the fuel cut is not executed for a period over a prescribed time period after a request to drive the valve 16 was placed. However in this case, such a compensation control is conducted that the EGR amount is corrected incrementally (or corrected decreasing) so as to reduce the NOx generation amount (or PM generation amount) after the exceptional drive is completed.

摘要： PROBLEM TO BE SOLVED: To provide a temperature control system capable of reducing costs and suppressing temperature error of a heating element.
SOLUTION: ECU (electric control unit) 40 opens and closes a power supply passage from a battery 21 to a glow plug 20 by GDU (glow plug driving unit) 30.

摘要： PROBLEM TO BE SOLVED: To secure stable operation of an actuator without making gas flow rate zero by stop of power supply to an actuator even if quantity of power supplied to the actuator of a valve element reaches an upper limit value in an exhaust gas recirculation control device. SOLUTION: ECU divides a numerical value range which duty value can take into a permissible range and a nonpermissible range determined from a point of view of stable operation of the actuator, stores a first threshold value dividing the permissible range and the nonpermissible range, and limits duty value to a second threshold value and moves the same to the permissible range not to make gas flow rate zero when difference between a target valve position and an actual valve position gets to a predetermined value or less and duty value moves to the first threshold value or the nonpermissible range from the permissible range. Consequently, duty value changes mostly in the permissible range even if the same temporarily moves in the nonpermissible range. Thus stable operation of the actuator can be secured without making gas flow rate zero. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide an EGR-gas temperature estimation device capable of accurately estimating the EGR-gas temperature at an outlet of an exhaust gas recirculation pipe by accurately estimating cooling efficiency of an EGR-gas cooling device. SOLUTION: The EGR-gas temperature estimation device for the internal combustion engine is equipped with the exhaust gas recirculation pipe 51 and the EGR-gas cooling device 53. The EGR-gas temperature estimation device obtains the cooling efficiency ηegr of the EGR-gas cooling device from the EGR-gas temperature Tex at the inlet of the exhaust gas recirculation pipe and an EGR-gas flow rate Gegr, and obtains the temperature THW of engine cooling water of refrigerator temperature in the EGR-gas cooling device. The EGR-gas temperature Tegr at the outlet of the exhaust gas recirculation pipe is calculated by the expression Tegr=Tex-ηegr ×(Tex-THW). Since the cooling efficiency ηegr greatly changes depending on the EGR-gas flow rate Gegr and the EGR-gas temperature Tex, the estimation device can accurately estimate the cooling efficiency ηegr, and therefore can accurately estimate the EGR-gas temperature Tegr.

摘要： PROBLEM TO BE SOLVED: To further properly set a threshold value becoming a standard for performing deposit removing operation in a valve control device for variably controlling the effective opening area of a flow passage by the rotational movement of a butterfly valve.
SOLUTION: A rotational movement range of the butterfly valve is divided into a plurality by a valve abnormality determining means of the valve control device, and threshold values CI and CII are set and prestored with respective divided rotational movement ranges I and II to a rotational resistance force index value corresponding to rotational resistance force acting against the rotational movement of the butterfly valve, and a determination is made on whether or not the rotational movement of the butterfly valve is slackened by comparing a detecting value of the rotational resistance force index value with the threshold values CI and CII in the respective rotational movement ranges. Thus, the further proper threshold values CI and CII can be set more than when uniformly setting the threshold values regardless of a rotational movement position like a conventional case.

摘要： PROBLEM TO BE SOLVED: To improve the estimation accuracy of an exhaust oxygen concentration by providing a means which feedback-controls the opening of an EGR valve so as to match an estimation value of the exhaust oxygen concentration to a target value.SOLUTION: A normative value of an EGR amount is preliminarily stored for each engine operating range. In the case of stable control in which an error between a corrected estimation value CEX_s of the exhaust oxygen concentration and a detection value CEX_sensor is within a predetermined range, and an error between the corrected estimation value CEX_s and a target value CEX_trg is within a predetermined range, a divergence amount ΔMEGR between a normative value MEGR_norm corresponding to the operating range of the moment and the corrected estimation value CEX_s is calculated (S25). Based on the divergence amount ΔMEGR, a consumed oxygen amount correction coefficient K1f (combustion parameter) showing a combustion state is corrected and learnt in association with the operating range of the moment (S30). The exhaust oxygen concentration is estimated using the learnt consumed oxygen amount correction coefficient K1f.
