摘要： Downstream side air-fuel ratio sensor signal based adaptive air-fuel ratio control. When the air-fuel ratio detected by the downstream side air-fuel ratio sensor is maintained lean unduly, a stuck learning control is performed to decrease a learning value to lower the air-fuel ratio. Adaptive learning value update control is performed based on the downstream side air-fuel ratio sensor signal to increase the learning value when an upstream air-fuel ratio deviates to the rich side and to decrease the learning value when the upstream air-fuel ratio deviates to the lean side. It is judged that the downstream side air-fuel ratio sensor is abnormal when a certain value or more of decrease of the learning value and a certain value or more of increase of the learning value are repeated.

摘要： In cases where a control device determines that a load is continuously less than a predetermined value for a predetermined period, the control device executes a first control to maintain the engine speed at a first rotation speed or higher, and when the control device determines that the load reached the predetermined value within the predetermined time, the control device executes a second control to maintain the engine speed at a second rotation speed or higher, which is higher than the first rotation speed. This provides a control device for an engine and an engine, which can restrain activation of an oil pressure switch attributed to an oil temperature.

摘要： This invention has an object to enable update of learning values of a large number of grid points in one session of a learning operation and also to easily adjust learning speed and efficiency in a wide learning region.
An engine 10 is provided with an ECU 60 for executing engine control by using various control parameters. The ECU 60 includes a learning map storing a learning value of the control parameter and executes weighting learning control of the learning value. In the weighting learning control, each time the control parameter is acquired, a weight w kij decreasing larger if a distance from a position of an acquired value z k of the control parameter to a grid point is larger is set to each of the grid points of the learning map. Then, on the basis of the acquired value z k of the control parameter and the weight w kij , the learning values Z ij (k) at all the grid points are updated. As a result, all the learning values can be efficiently updated in one session of the learning operation.摘要翻译： 本发明的目的在于能够在一次学习操作中更新大量网格点的学习值，并且还能够在宽广的学习区域中容易地调整学习速度和效率。 发动机10设置有用于通过使用各种控制参数来执行发动机控制的ECU 60。 ECU 60包括存储控制参数的学习值的学习图并且执行学习值的加权学习控制。 在加权学习控制中，每当获取控制参数时，如果从控制参数的获取值zk的位置到网格点的距离较大，则将权重wkij减小得更大， 学习地图。 然后，基于所获得的控制参数值zk和权重wkij，更新所有网格点处的学习值Zij（k）。 结果，所有学习值可以在学习操作的一个会话中有效地更新。

摘要： The present invention provides for a system for adjusting NOx estimations based on the calculation of an error given by the difference between a first measured value obtained from a NOx sensor (7") and a second one estimated from a NOx estimation (6"). Said sensor (7") can be used in an adaptation loop so as the expected NOx emissions match the ones measured with the NOx sensor under steady-state conditions.
