  • In a combined cycle system having a multi-pressure heat recovery steam generator, a gas turbine and steam turbine, steam for cooling gas turbine components is supplied from the intermediate pressure section of the heat recovery steam generator supplemented by a portion of the steam exhausting from the HP section of the steam turbine, steam from the gas turbine cooling cycle and the exhaust from the HP section of the steam turbine are combined for flow through a reheat section of the HRSG. The reheated steam is supplied to the IP section inlet of the steam turbine. Thus, where gas turbinemore » cooling steam temperature is lower than optimum, a net improvement in performance is achieved by flowing the cooling steam exhausting from the gas turbine and the exhaust steam from the high pressure section of the steam turbine in series through the reheater of the HRSG for applying steam at optimum temperature to the IP section of the steam turbine.« less
  • A cooling fan coupling system is described for an engine for an automotive vehicle, the engine comprising a rotating member and a coolant circulation system comprising a coolant radiator, a cooling fan for propelling air past the radiator to cool the coolant radiator, and a thermostatic valve for controlling flow of coolant through the coolant radiator. The thermostatic valve is constituted to start to open at a first determinate coolant temperature value, to be fully opened at a second determinate coolant temperature value, and to be partly opened at a third determinate coolant temperature value and the second determinate coolantmore » temperature value and the second determinate coolant temperature value.« less
  • An apparatus is described for cooling a cylinder head of an engine comprising: a cylinder head cover in the form of a plate adapted to fully cover an upper opened surface of the cylinder head. The cylinder head cover is formed in an upper wall thereof with an insert hole for inserting an ignition plug fitting and removing tool. The insert hole is formed on an inner wall thereof with an inclined guide groove for guiding the ignition plug fitting and removing tool; an oil passage formed in the cylinder head cover, one end of the oil passage being openedmore » at a side portion of the cylinder head cover and the other end being branched such that the branched ends extend around a plug seat in the cylinder head; a recess formed around the plug seat in the cylinder head; covers adapted to cover the recess; and nozzles each disposed between the recess and the other end of the oil passage, one end of the nozzle connecting with the other end of the oil passage and the other end extending into the recess. Lubricating oil pumped up from an oil pan is fed via the oil passage and the nozzle and is spouted into the recess so as to cool the engine.« less
  • Apparatus and method are described for improving the operation of an internal combustion engine and reducing hydrocarbons emissions therefrom by cooling the fuel during its passage from the fuel supply tank to the intake manifold.
  • An apparatus is described for cooling the cylinder head of an engine, wherein oil introducing means for introducing oil to the area located above the combustion chambers in the cylinder head is arranged at the position located in the vicinity of each of ignition plug fitting bosses in the cylinder head, oil feeding passages by way of which oil is delivered to the oil introducing means are formed on the cylinder head cover fixedly mounted on the cylinder head, cover fixedly mounted on the cylinder head, each of the oil supplying passages includes a main passage extending in the longitudinalmore » direction of the cylinder head and a flow rate adjusting device for adjusting a flow rate of oil flowing through a branched passaged branched from the main passage is disposed at the extreme end of the main passage.« less
