Abstract: Provided is an exhaust gas purification apparatus having a control device that monitors the transition of a detection value of each of an upstream NOx sensor and a downstream NOx sensor, and when the NOx purification rate of the SCR catalyst falls to a value of a first threshold or lower, generates an abnormality detection signal indicating that an over storage state has occurred in an SCR catalyst if the amount of change in the detection value of the upstream NOx sensor per unit time is at least a second threshold and the amount of change in the detection value of the downstream NOx sensor per unit time is at most a third threshold.

Abstract: An electronic fuel injection apparatus for a diesel engine comprising a driving state detection means for detecting a driving state of a vehicle associated with an automatic transmission and a controller for periodically determining a target injection quantity based on the driving state. The target injection quantity at a time when a gearshift position is in a driving position is set to a driving target injection quantity which is obtained by adding a predetermined correction quantity to a target injection quantity at a time when the gearshift position is in a non-driving position. When the change of the gearshift position from the non-driving position to the driving position is detected, the target injection quantity is increasingly corrected to the driving target injection quantity.

Abstract: An apparatus for controlling a transmission includes a detecting device for detecting the speed of rotation of an electric motor of a selecting actuator and a learning device for learning angular positions of the motor which correspond respectively to gear selecting positions based on a detected signal from the detecting device. Gear selecting operation of the selecting actuator is controlled by the learned angular positions of the motor.
