Abstract: In a control device for an internal combustion engine including an air-fuel ratio sensor that includes a catalyst layer that covers an exhaust gas-side electrode, an oxygen storage capacity of the catalyst layer is acquired based on a sensor output of the air-fuel ratio sensor. The sensor output is corrected if the oxygen storage capacity is higher than a predetermined value and the sensor output is in a predetermined range in the vicinity of the theoretical air-fuel ratio. Preferably, the oxygen storage capacity is calculated by integrating the product of a deviation amount ?A/F of the sensor output with respect to the theoretical air-fuel ratio and a dwell time thereof. A correction period in which a correction operation is performed is set based on the oxygen storage capacity.

Abstract: Disclosed herein are embodiments of combined cycle power plants having elevated exhaust pressure from a steam turbine. The elevated exhaust pressure from the steam turbine may result in an elevated condensate pressure and temperature. A cooling system removes sensible heat from the condensate. The elevated condensate temperature results in a greater temperature difference between the condensate and the working medium in the cooling system. The amount of heat that is dissipated by the cooling system is proportionate to the heat transfer surface and the temperature difference between the condensate and the working medium. As a result of the greater temperature difference, a smaller cooling system configured to operate with a higher temperature condensate may be utilized in place of a larger cooling system configured to operate with lower temperature condensate. By reducing the size of the cooling system, the overall size of the combined cycle power plant may be reduced.
