A heat conduction member includes: a cylindrical ceramic body, a metal pipe on the outer periphery side of the cylindrical ceramic body, and an intermediate member held between the cylindrical ceramic body and the metal pipe. The cylindrical ceramic body has passages passing through from one end face to the other end face and allowing the first fluid to flow therethrough. The intermediate member is made of material having at least a part having a Young's modulus of 150 Gpa or less. The first fluid is allowed to flow through the inside of the cylindrical ceramic body while the second fluid having lower temperature than that of the first fluid is allowed to flow on the outer peripheral face side of the metal pipe to perform heat exchange between the first fluid and the second fluid.

A cooling water control apparatus has a setting device which sets a target heat amount line such that a condition where a transferred heat amount which is transferred to a heater core is equal to a required heat amount which is required by the heater core is satisfied at a desired time point at which the transferred heat amount starts to be actually used, the target heat amount line representing a successive target value of the transferred heat amount during a period until the desired time point; and a first controlling device which makes a cooling water circulate in a first pipe, stops the circulation of the cooling water in a second pipe and adjusts an output of an engine such that the transferred heat amount follows the target heat amount line.

A water recovery device includes: an exhaust gas pipe that is connected to a combustion device; a water generation unit that generates water by cooling exhaust gas in the exhaust gas pipe to condense water vapor in the exhaust gas; and a water container that stores water generated by the water generation unit. The water generation unit includes: an acoustic-wave generator that generates acoustic waves by absorbing heat from the exhaust gas pipe and giving the heat to working fluid, which transmits acoustic waves by oscillating, to cause the working fluid to oscillate; a transmission pipe that is internally filled with the working fluid and transmits acoustic waves generated by the acoustic-wave generator; and a cold-heat generator that generates cold heat to supply the cold heat to the exhaust gas pipe by receiving acoustic waves transmitted through the transmission pipe and giving heat to the acoustic waves.

A method for controlling a vehicle propulsion system. More particularly, the method estimates a future, upcoming driving condition and controls the vehicle propulsion system to operate the prime mover in a specific operation mode based on a determined regeneration level of a particle filter for the estimated future, upcoming driving condition.

An apparatus comprises an input chamber being configured for accepting a flow of material. An output chamber is configured for flowing the material along a first pathway and a second pathway. A diverter member is disposed within the input chamber. The diverter member comprises a half wing shape pivotally joined at a juncture of the input chamber and the output chamber. The diverter member is operable to be positioned at a first position for diverting the flow to the first pathway and to be positioned at a second position for diverting the flow to the second pathway. A lever mechanism is configured to be operable for moving the diverter member between the first position and the second position in which the flow is uninterrupted.

A method and system are disclosed for safe, efficient, economically productive, environmentally responsible, extraction and utilization of dissolved gases in deep waters of a rare type of “exploding” lake, where methane (CH.sub.4) is accompanied by abundant CO.sub.2. CH.sub.4 is combusted to generate electricity. CO.sub.2 usually is considered a contaminant requiring removal to avoid power loss. Cleaning high CO.sub.2 levels from CH.sub.4, however, is costly and causes CH.sub.4 loss. Venting CO.sub.2 is environmentally undesirable. Or, if CO.sub.2 is disposed in water flow returned to the deep lake, danger persists. CO.sub.2 and CH.sub.4 are degassed efficiently together and input into oxy-fuel combustion. Three process outputs are: degassed nutrients-rich water flow, power and CO.sub.2+H.sub.2O exhaust, all usable for industrially productive purposes. Extracting and using both gases together in an integrated method advances safety, economic productivity and environmental stewardship. Previously, it has not been possible to accomplish these ends together. The invention provides a hyper-efficient way.

A method includes receiving information indicative of a temperature of exhaust gas emitted from an engine operating at an engine speed, determining that the temperature of the exhaust gas is below a predefined temperature threshold, determining an engine load sized to increase the temperature of the exhaust gas above the predefined temperature threshold, increasing a load on the engine to the determined engine load while maintaining the engine at the engine speed by increasing at least one of a fuel flow rate and a fuel flow pressure of the fuel pump powered by the engine, and diverting the excess fuel from the fuel flow path upstream of the engine. Increasing at least one of the fuel flow rate and the fuel pressure of the fuel pump causes excess fuel to be provided to the engine than is necessary to maintain the engine at the engine speed.

An emission signature modification device for modifying an acoustic signature of an exhaust gas stream, including an exhaust gas guiding device that guides the exhaust gas stream in the flow direction thereof from an inlet area to an outlet area. An active acoustic emission modification device modifies the acoustic emission of the exhaust gas stream in predetermined operating states. If an actuator system of the active acoustic emission modification device is designed such that in a circumferential direction, the actuator system is surrounded by more than 30% of the guided exhaust gas stream, the actuating system can be protected against harmful influences from the environment by way of the exhaust gas guiding device on the one hand, and on the other hand, the required space signifier can be reduced as compared to a lateral, external arrangement of the actuating system.
