Abstract: A method is for route identification that is conducive for successful diagnosis of an exhaust gas treatment system of a vehicle. In the method, an ECU in the vehicle receives a value of GPS coordinates from a GPS module, and the ECU retrieves a value of day, date, and time from an ECU clock. The ECU monitors a value of engine operating conditions with reference to the received value of GPS coordinates and the retrieved value of day, date, and time. The ECU identifies a segment of GPS coordinates for successful diagnosis of an exhaust gas treatment system based on the monitored value. Upon the identification, the segment of GPS coordinates is stored in ECU memory.

Abstract: In an electromagnetic fuel injection valve, a plurality of recess parts are provided in an attracted face of a movable core, the recess parts dividing a taper face of the movable core into a plurality of sections along a peripheral direction of the movable core. Accordingly, a fuel oil film present in an engaged part between an annular projection of a fixed core and the taper face is sectioned at a plurality of locations, thereby suppressing a sticking phenomenon of the engaged part caused by the fuel oil film. Therefore, when energization of a coil is cut off, a delay in detachment of the movable core from the fixed core is eliminated, thus contributing to improvement of valve-closing responsiveness.
