摘要： An inter-cylinder air-fuel ratio imbalance determination apparatus (determination apparatus) according to the present invention obtains, as an “EGR supplying state imbalance determination parameter”, a value corresponding to a differential value d(abyfs)dt of a detected air-fuel ratio abyfs represented by an output value of an air-fuel ratio sensor when an EGR gas is being supplied, and obtains, as an “EGR stop state imbalance determination parameter”, a value corresponding to a differential value d(abyfs)dt when an EGR gas supply is being stopped. The determination apparatus obtains an “EGR-causing imbalance determination parameter Pegr” by subtracting the EGR stop state imbalance determination parameter Poff from the EGR supplying state imbalance determination parameter Pon, and determines that an inter-cylinder air-fuel ratio imbalance state has occurred due to the supply of the EGR gas when the parameter Pegr is larger than a threshold Pegrth.

摘要： An apparatus for determining an air-fuel ratio imbalance among cylinders based on an output value of an air-fuel ratio sensor, an imbalance determination parameter which becomes larger or smaller as a difference among air-fuel ratios becomes larger, and performs determining an air-fuel ratio imbalance among cylinders based on a result of a comparison between the imbalance determination parameter and a imbalance determination threshold. The determining apparatus calculates a purge correction coefficient which compensates for a change in the air-fuel ratio due to an evaporated fuel gas which is generated in a fuel tank, while the evaporated fuel gas is being introduced into an intake passage, and corrects a fuel injection amount with the purge correction coefficient FPG.

摘要： The present invention provides a mechanical seal sliding member with high lubricating characteristics, in which the coefficient of friction and the temperature of sliding surfaces are lowered and stabilized without excessive leakage. In the mechanical seal sliding member of the present invention, on the sliding surface 2, a plurality of grating sections 5 are formed separately in each of which a plurality of linear shape ridge portions parallel to each other are formed in a predetermined region with a predetermined pitch. The linear shape ridge portions of the plurality of grating sections are formed as inclined at a predetermined angle to a sliding direction of the sliding surfaces 2. Such periodic structure can improve the lubricating characteristics for lubrication. By irradiating a linearly polarized femtosecond laser with irradiating energy adjacent to a process threshold level to a material surface, a fine periodic structure with a cycle interval comparable with a laser wavelength and with a ridge depth half or less than the laser wavelength can be formed by a self-structuring manner.
