摘要： A turbine of a turbocompound engine (10) for extracting energy from the exhaust fluid flow of an and a controller (40) thereof is described. The turbine (10) comprises a housing (30); a turbine wheel (12) rotatably coupled within the housing (30) and rotatable by a fluid flow to provide a rotational output (14); a variable load (34) applying a load to the rotational output; and a controller (40). The controller (40) is configured to: receive information (404) relating to the operating conditions of the turbine (10); calculate an optimum operating velocity (402) of the rotational output based on the operating conditions; and supply a signal (410) to the variable load (34) to vary the load applied to the rotational output (14) in response to said operating conditions so that the rotational output (14) rotates at a corrected operating velocity (408). Such an arrangement increases the ability to operate the turbine at its optimum operating velocity.

摘要： A fuel injection system (70) for a gas turbine engine (20) can be used to ensure successful transition in all conditions, while avoiding the possibility of steady state, or increasing power mode, operations with an insufficiently filled secondary fuel line (78). This may be accomplished by altering a pressure in a secondary fuel line (78). The present disclosure allows for the elimination of individual fuel injector valves, which may reduce the total complexity and number of parts of the fuel injection system.

摘要： The present invention relates to a water supply apparatus that pressurizes water from a water main pipe to supply the water to a building, such as an apartment building, a commercial building, or the like. The water supply apparatus includes a controller (10) storing a first lower limit value L1 higher than a shutoff rotational speed N0 and a second lower limit value L2 lower than the shutoff rotational speed, which is a rotational speed required for achieving a target pressure PA in a shutoff state. The controller (10) is configured to switch a lower limit of the rotational speed of the pump (1) from the first lower limit value L1 to the second lower limit value L2, and determine that the pump (1) is in a low-flow-rate state if the rotational speed of the pump (1) becomes equal to or lower than the shutoff rotational speed N0 within a predetermined detection time.
