Abstract: A system for purifying exhaust gas generated by an internal combustion engine having a bypass exhaust gas passage branching from an exhaust pipe which is opened or closed by a switch-over valve, and an adsorbent which adsorbs unburneds component in the exhaust gas installed at the bypass exhaust passage. In the system, when the engine operation is within a high engine speed and high load region, the switch-over valve is operated to open the bypass exhaust gas passage to reduce noise due to switch-over valve chattering, etc. Similarly, the bypass exhaust gas passage is opened at that range, when the exhaust gas temperature is greater or equal to a predetermined value, to introduce high temperature exhaust gas to burn away cloggy material adhered to the adsorbent which would otherwise deteriorate or degrade the adsorbent.

Abstract: A plant control system has a reference value setting unit for variably setting a reference value for an air-fuel ratio to be given to an exhaust system including a catalytic converter, depending on a component based on an adaptive control law of a manipulated variable of the air-fuel ratio generated by a controller according to an adaptive sliding mode control process in order to converge an output of an O2 sensor disposed downstream of the catalytic converter to a target value. The manipulated variable generated by the controller represents the difference between the air-fuel ratio and the reference value, required to converge the output of the O2 sensor to the target value.

Abstract: A base sheet path for peeled issue for guiding a base sheet in a direction different from a label issue port after passing a peeling section following the printing by a printing section and a base sheet path for continuous issue for guiding the base sheet to the label issue port with labels printed by the printing section stuck on the base sheet are provided. Two operating modes, namely, the label peeled issue mode in which the base sheet is set to the base sheet path for peeled issue and the label continuous issue mode in which the base sheet is set to the base sheet path for continuous issue are executed selectively. In this case, depending on the result of detection by a base sheet sensor arranged facing the base sheet path for peeled issue for detecting the presence of the base sheet, namely, depending on the setting state of the base sheet, the label peeled issue mode or the label continuous issue mode is recognized automatically for determining the issue mode. Namely, depending on the difference between the positions at which the base sheet is set in the label peeled issue mode and the label continuous issue mode, the label issue mode is recognized without adding an issue mode parameter to an issue command.

Abstract: An air-fuel ratio control system for an internal combustion engine has a first air-fuel ratio sensor arranged in an exhaust passage at a location upstream of a catalyst and a second air-fuel ratio sensor arranged in the exhaust passage at a location downstream of the catalyst. In response to an output from the first air-fuel ratio sensor, an air-fuel ratio correction coefficient is calculated for correcting an amount of fuel supplied to the engine in a manner such that an air-fuel ratio of a mixture supplied to the engine is converged to a desired air-fuel ratio. In response to an output from the second air-fuel ratio sensor, a desired air-fuel ratio correction amount is calculated for correcting the desired air-fuel ratio. A learned value of the desired air-fuel ratio correction amount is calculated, and the desired air-fuel ratio is corrected. Calculation of the learned value of the desired air-fuel ratio correction amount is permitted depending on a ratio between a time period over which the output from the second air-fuel ratio sensor is on a richer side with respect to a predetermined reference value and a time period over which the output from the second air-fuel ratio sensor is on a leaner side with respect to the predetermined reference value.

Abstract: An exhaust purification system for an internal combustion engine is provided that can maintain the NOx purification rate of a selective reduction catalyst at near the maximum thereof. The exhaust purification system is provided with an oxidation catalyst and CSF provided in the exhaust plumbing of the engine, a selective reduction catalyst that is provided in the exhaust plumbing on the downstream side of oxidation catalyst and CSF, and selectively reduces NOx in the exhaust, and a NO2 sensor that detects NO2 in the exhaust inside of the exhaust plumbing on the downstream side of the selective reduction catalyst. An ECU executes NO2-NOx ratio decrease processing to cause the NO2-NOx ratio corresponding to the ratio of NO2 to NOx in the exhaust flowing into the selective reduction catalyst to decrease, in a case of a detection value Vno2 from the NO2 sensor being greater than a predetermined value Vno2_th.

Abstract: In a control apparatus for an automatic transmission, it is configured to calculate a change amount (ΔNC estimation value) of an output rotational speed of the transmission (S10); calculate an average (I phase initial average G) of the change amount of the output rotational speed over a predetermined period of an initial inertia (I) phase of shifting; calculate an average (after-shift average G) of a vehicle acceleration after the completion of the shifting, assuming that the change amount of the output rotational speed indicates the vehicle acceleration G; calculate a difference (I phase initial G) between the average of the change amount of the output rotational speed and the average of the vehicle acceleration; incrementally and decrementally correct the desired value of the transmission torque of the frictional engaging element such that the calculated difference falls within a predetermined range; and control supply of hydraulic pressure to the frictional engaging element such that it becomes the corrected desired value (S14 to S20). With this, since the vehicle acceleration at shifting is estimated and evaluated and based thereon, variation in the transmission torque of the frictional engaging element, etc., is learned, it becomes possible to fully exploit the potential of the frictional engaging element, thereby improving a feel given to the vehicle occupant(s) at shifting.

Abstract: An EGR control apparatus for an internal combustion engine, which is capable of properly controlling an inert gas amount of two types of EGR gas supplied to cylinders of the engine via two paths different from each other, thereby making it possible to ensure a stable combustion state, reduced exhaust emissions, and improve operability.
