Abstract: A hybrid vehicle is equipped with an internal combustion engine, a motor/generator, and a Rankine cycle system for recovering thermal energy of exhaust gas. The output of the Rankine cycle system is input into a transmission or, alternatively, converted into electric power and used for charging a battery. The Rankine cycle system has temperature setter that sets the temperature of steam at the outlet of an evaporator. A pressure setter is provided for setting steam pressure at the inlet of an expander. A pressure controller is provided for controlling the steam pressure at the inlet of the expander. The evaporator generates steam to be supplied at a pressure that is optimum for the expansion ratio of the expander. The Rankine cycle system is operated when the vehicle is accelerating or cruising and efficiently recovers thermal energy of the exhaust gas and reduces the fuel consumption of the internal combustion engine.

Abstract: Provided is a load balancing method for a computer system having one or more host computers, one or more storage systems, and a management computer. Each storage system has a physical disk for storing data that is requested by the host computer to be written, and a disk controller for controlling the physical disk. The load balancing method is characterized in that the storage system provides a storage area of the physical disk as one or more logical units to the host computer, and that the management computer calculates the processing amount of a component passed by a logical path, and refers to the calculated processing amount of the component when distributing, to the logical path, I/O issued from the host computer. Accordingly, it is possible to choose which path to use for access appropriately.

Abstract: A Rankine cycle system includes an evaporator for heating water with thermal energy of exhaust gas of an engine for generating steam with a displacement type expander for converting thermal energy into mechanical energy. A temperature controller manipulates the amount of water supplied to the evaporator so that the temperature of the steam supplied from the evaporator to the expander coincides with a target temperature. A pressure controller manipulates the rotational speed of the expander by changing a load of the expander so that the pressure of the steam supplied from the evaporator to the expander coincides with a target pressure. The temperature controller and/or the pressure controller continue to control the amount of water supplied to the evaporator and/or the rotational speed of the expander in set ranges at least in a state in which the engine has stopped and the thermal energy of the exhaust gas has disappeared.

The distribution device controls a distribution ratio between the amount of water supplied to the entrance of the evaporator and the amount of water supplied to a portion partway along the evaporator, thereby suppressing an overshoot in the temperature of the gas-phase working medium due to a sudden increase in the thermal energy of the exhaust gas.

Abstract: A Rankine cycle system is provided in which, in order to make a pressure (P) of a gas-phase working medium at the inlet of an expander (13) coincide with a target pressure (PO), a feedforward value (NFF) is calculated on the basis of the target pressure (PO) and a flow rate (Q) of the gas-phase working medium at the outlet of an evaporator (12), a feedback value (NFB) is calculated by multiplying a deviation (?P) of the pressure (P) of the gas-phase working medium at the inlet of the expander (13) from the target pressure (PO) by a feedback gain (kp) calculated on the basis of the flow rate (Q) of the gas-phase working medium, and the rotational speed of the expander (13) is controlled on the basis of the result of addition/subtraction of the feedforward value (NFF) and the feedback value (NFB).

Abstract: A Rankine cycle system is provided in which the amount of water supplied to an evaporator (12) and the rotational speed of an expander (13) are controlled so as to make the temperature of steam at the outlet of the evaporator (12) coincide with a target steam temperature. When the amount of water supplied to the evaporator (12) is decreased stepwise, the temperature of the steam at the outlet of the evaporator (12) increases slowly and converges to a predetermined temperature. When the rotational speed of the expander (13) is decreased stepwise the steam temperature increases quickly, although the increase is temporary.

Abstract: Evaporator temperature control means (U) that, in order to make the temperature of steam generated by heating water using exhaust gas of an engine coincide with a target temperature, controls the amount of water supplied to the evaporator based on the flow rate of the exhaust gas, the temperature of the exhaust gas, the temperature of the water, and the temperature of the steam. Calculating an exhaust gas flow rate (Gmix) based on a fuel injection quantity, an air/fuel ratio, and a rotational speed of the engine improves the precision and the responsiveness of the calculation. Controlling the amount of water supplied to the evaporator based on this exhaust gas flow rate (Gmix) therefore improves the accuracy with which the steam temperature is controlled so as to make it coincide with the target temperature.
