摘要:
A method for minimizing emission output from a diesel powered system having at least one diesel-fueled power generating unit, the method including determining at least one power level required from the diesel powered system in order to accomplish a specified mission, determining an emission output based on the power level required, and using at least one other power level that results in a lower emission output wherein the overall resulting power is proximate the power required.
摘要:
A method for determining the configuration of a diesel powered system having at least one diesel-fueled power generating unit, the method including a step for determining a minimum power required from the diesel powered system in order to accomplish a specified mission, and a step for determining an operating condition of the diesel-fueled power generating unit such that the minimum power requirement is satisfied while yielding at least one of lower fuel consumption and lower emissions for the diesel powered system.
摘要:
A method is provided including determining a first power level required from a diesel powered system. The first power level corresponds to a first proportion of a maximum power. The method also includes determining an emission output for a mission based on the first power level. The method further includes determining a second power level corresponding to a second proportion of the maximum power, wherein alternate use of the second power level and at least one of the first power level or a third power level results in a lower emission output for the mission, with the overall resulting power being proximate the minimum power required. The method also includes automatically controlling operation of the diesel powered system by using the second power level alternately with at least one of the first power level or the third power level.

A diffuser (30) for a centrifugal compressor (60) having a flow slot (34) formed between the leading edge portion (36) of a diffuser vane (32) and an adjoining diffuser wall (70) for the passage of working fluid (67) over the vane from the pressure side ((40) to the suction side (42) of the vane. The portion (38) of the working fluid passing over the vane is injected into the flow boundary region (43), thereby minimizing the growth of a flow separation zone (58) along the suction side.
摘要:
A method for operating a diesel powered system having at least one diesel-fueled power generating unit, the method including evaluating an operating characteristic of the diesel powered system, comparing the operating characteristic to a desired value to satisfy a mission objective, and adjusting the operating characteristic to correspond to the desired value with a closed-loop control system that operates on a feedback principle to satisfy a mission objective. A system and a computer software code are also disclosed for operating a diesel powered system having at least one diesel-fueled power generating unit.
摘要:
A flexible hose (1) with a corrugated wall (2), comprising an internal surface (3) with projections (4, 5) and recesses (6, 7), said hose (1) being obtained by moulding a plastic material, wherein each internal projection (4, 5) comprises a substantially flat and smooth top face (8, 9). Each top face (8, 9) has a first width (W1) and each internal recess has a second width (W2). The ratio between first width and second width (W1/W2) is preferably larger than or equal to 2.2. The hose may comprise a hollow longitudinal protuberance or score.
