摘要： An air-fuel ratio imbalance among cylinders determining apparatus (a determining apparatus) according to an aspect of the present invention, obtains a parameter X for imbalance determination which becomes larger as a variation of an air-fuel ratio of an exhaust gas passing through a position at which the air-fuel ratio sensor is disposed becomes larger, based on an output value Vabyfs of an air-fuel ratio sensor 67. At the same time, the determining apparatus changes a target air-fuel ratio which is a target value of an air-fuel ratio of a mixture supplied to an engine to “an air-fuel ratio (a target rich air-fuel ratio AFrich or a target lean air-fuel ratio AFlean) other than a stoichiometric air-fuel ratio” from the stoichiometric air-fuel ratio. Accordingly, the determining apparatus can obtain the parameter X for imbalance determination in a state in which a responsivity of the air-fuel ratio sensor 67 is not low. As a result, it can make a determination on the air-fuel ratio imbalance among cylinders with high accuracy.

摘要： A warm-up system for an exhaust system of an internal combustion engine includes an electronic control unit that performs warm-up control for warming up an exhaust system component upon start-up of the internal combustion engine and a failure diagnosis performing module of the electronic control unit that performs failure diagnosis for the exhaust system component after the completion of warm-up of the exhaust system component. If the internal combustion engine repeatedly stops before completion of the failure diagnosis for a predetermined period of time, then the electronic control unit changes the warm-up control performed upon start-up of the internal combustion engine to a control that raises the temperature of the exhaust system component more quickly than the warm-up control performed during the predetermined period.

摘要： In a fuel injection system of an internal combustion engine in which a first fuel, which has a property to inhibit the adsorption of exhaust gas components by an exhaust gas purification catalyst, and the second fuel, which has a property not to inhibit the adsorption of the exhaust gas components by the exhaust gas purification catalyst, are able to be selectively used, the present invention has a task to decrease an amount of consumption of the second fuel in a suitable manner. In order to solve this task, the fuel injection system of an internal combustion engine according the present invention is constructed such that the second fuel is first supplied to the internal combustion engine when the exhaust gas purification catalyst is in a cold state, and a change from the second fuel to the first fuel is then made before the exhaust gas purification catalyst subsequently rises in temperature to an activation temperature thereof.

摘要： To provide a method for enhancing adhesion of a thin film, and a method for enhancing adhesion of a thin film provided with a surface function caused by the shape. Adhesion of a thin film can be enhanced by irradiating the surface of a parent material with a laser beam at a fluence in the vicinity of the machining threshold, scanning the irradiated part while overlapping to form a grating structure, and then forming a solid thin film in the grating structure. When the grating structure formed on the parent material is left on the solid thin film, adhesion of the thin film is enhanced and surface functions, e.g. reduction of friction and wear caused by the shape, suppression of adhesion of fine particles, and cell sensibility, can be exhibited in conjunction with the function of the solid thin film.

摘要： An inter-cylinder air-fuel imbalance determination apparatus according to the present invention obtains, based on the output value of the air-fuel ratio sensor, an air-fuel ratio fluctuation indicating amount whose absolute value becomes larger as a fluctuation of the air-fuel ratio of the exhaust gas passing through the air-fuel ratio sensor becomes larger, and further obtains an imbalance determination parameter which becomes larger as an absolute value of the air-fuel ratio fluctuation indicating amount becomes larger. In addition, the determination apparatus obtains an average value of the air-fuel ratio of the exhaust gas when the imbalance determination parameter is being obtained, and obtains an imbalance determination threshold which becomes smaller as the average value of the air-fuel ratio is closer to the stoichiometric air-fuel ratio. The determination apparatus determines that an inter-cylinder air-fuel ratio imbalance state has been occurring when the imbalance determination parameter is larger than the imbalance determination threshold.
