摘要： PURPOSE:To accurately control an injection quantity and accelerate atomization by increasing the number of times of fuel injection when injection quantity at one time is above a defined value while reducing the number of times when below a defined value in a device which carriers out an air-fuel ratio feedback control. CONSTITUTION:An electronic controlling device 32 receives signals from a throttle position sensor 18, an intake pressure sensor 20, an O2 sensor 30, etc. and outputs a fuel injection signals to fuel injection valves 22 to carry out the feedback control of air-fuel ratio. The electronic controlling device 32 judges whether a learned value which is added to each injecting time by the air-fuel ratio feedback control is within a defined range or not and, when it is above a defined value, the number of times of injection is increased while reducing the number of times when it is below a defined value, to keep the learned value within the defined range.

摘要： PROBLEM TO BE SOLVED: To suppress the distortion in the outer peripheral shape of an inner ring member while maintaining a small number of components, when the rotating member, provided with the inner ring member and an outer ring member which are relatively rotatably arranged in inner and outer positions in the radial direction, is mounted to a member formed of a plate member to be mounted with the rotating member. SOLUTION: The inner ring member 37 is fitted and secured onto a projection portion 63 integrally formed with and projecting from an end face of the member 55 to which the rotating member is to be mounted. In the structure for fitting and securing the inner ring member 37 onto the projection portion 63, the inner ring member 37 is formed with a square through-hole 39 which extends therethrough in the axial direction and the projection portion 63 is inserted in the through-hole 39 and is subject to plastic deformation so that a front end 63t of the projection portion 63 is expanded outwardly in the radial direction, whereby the inner ring member 37 is secured by caulking to the member 55 to which the rotating member is to be mounted. The shape of the projection portion 63 upon securing by caulking is such that there are no corner portions fitted in the corner portions of the through-hole 39 at least in the plastic-deformed range in the axial direction.

摘要： PROBLEM TO BE SOLVED: To enhance NOx storage capability and the NOx purifying rate of a NOx storage-reduction catalyst.
SOLUTION: An upstream catalyst (28U) and a downstream catalyst (28D) are arranged in series and are housed in a common casing (25) disposed in an engine exhaust passage. The upstream catalyst (28U) consists of the NOx storage-reduction catalyst that adsorbs NOx contained in incoming exhaust gas when the air-fuel ratio of the incoming exhaust gas is lean, and releases and reduces the adsorbed NOx when the air-fuel ratio of the incoming exhaust gas becomes rich, and the downstream catalyst consists of a three-way catalyst. The upstream catalyst (28U) has a higher oxidizing capacity than the downstream catalyst (28D), and the downstream catalyst (28D) has a higher reducing capacity than the upstream catalyst (28U). The upstream catalyst (28U) has multilayered structure including an upper layer and a lower layer, and is prepared such that the upper layer has a higher oxidizing capability than the lower layer, and the lower layer has a higher reducing capability than the upper layer.

摘要： PROBLEM TO BE SOLVED: To provide a guide roller for a sliding door, which prevents a hindrance to a sliding door opening/closing operation by smoothly rotating even if a roller is inclined with respect to a guide rail.
SOLUTION: This guide roller 1, which is rotatably held on a supporting shaft 2 erected from a leading end of the supporting arm provided on the sliding door of the vehicle, rolls in the approximately U-shaped cross-section guide rail 3 installed in a vehicle body, in the opening/closing of the sliding door. The guide roller for the sliding door of the vehicle makes a vertical angle of inclination changed along with door opening/closing movement. In the guide roller, a longitudinal section of a peripheral surface of an outside diameter portion 11 guided by an inner surface of the guide rail 2 is formed in such a shape as to be gently and convexly curved toward the inner surface, and a longitudinal section of a peripheral surface of an inside diameter portion 10, through which the supporting shaft 2 passes, is formed in such a shape as to be gently and convexly curved toward the supporting shaft 2, so that the inside diameter portion 10 cannot be strongly pressed against the supporting shaft 2 when the sliding door is inclined.

摘要： PROBLEM TO BE SOLVED: To provide an exhaust emission control device for an internal combustion engine capable of inhibiting formation of cyanic acid by appropriately executing urea injection control. SOLUTION: The exhaust emission control device for the internal combustion engine is suitably used for purifying exhaust gas with using a NOx storage reduction catalyst and a NOx selective reduction catalyst. The NOx selective reduction catalyst is provided at a downstream side of the NOx storage reduction catalyst in an exhaust gas passage. The exhaust emission control device for the internal combustion engine is moreover provided with an urea injection means and an urea injection control means. The urea injection means is, for example, an injection valve injecting urea into the exhaust gas passage. The urea injection control means stops urea injection by the urea injection means when catalyst temperature of the NOx storage reduction catalyst and/or the NOx selective reduction catalyst is not more than predetermined temperature. Consequently, formation of cyanic acid can be inhibited and leak of cyanic acid from the NOx storage reduction catalyst and/or the NOx selective reduction catalyst can be inhibited.
