    • An engine exhaust gas purifier includes: an injection controller allowing a fuel injection valve to inject fuel near the top dead center on each compression stroke; an EGR amount controller for controlling the amount of exhaust gas recirculated into a combustion chamber; an excess air ratio controller for controlling the excess air ratio so that the local equivalence ratio in a late combustion stage is lower than the equivalence ratio at which soot is produced; and an intake air temperature controller for controlling the temperature of intake air after being mixed with exhaust gas. The intake air temperature controller controls the temperature of intake air within a temperature range lower than an upper temperature limit below which a predetermined ignition delay time can be secured and higher than a lower temperature limit above which the production of HC and CO can be avoided.

    • A polishing estimation/evaluation device includes a dividing unit, an overpolished area extracting unit, and a dummy modifying unit. The dividing unit divides a layout of an integrated circuit into a plurality of partial areas. The overpolished area extracting unit refers to an overpolishing condition indicating whether overpolishing occurs in a vicinity of a partial area based on a wiring density in the partial area and a wiring density in surrounding areas of the partial area, and extracts a partial area where the overpolishing occurs from the plurality of partial areas obtained by the division by the dividing unit. The dummy modifying unit modifies dummy wiring in the partial area where the overpolishing occurs extracted by the overpolished area extracting unit and/or dummy wiring in surrounding areas of the partial area to reduce the number of partial areas where the overpolishing occurs.
