  • Patent number: 8621916
    Abstract: A system for measuring an injection process includes a measurement chamber filled with a fluid. An injection valve injects the fluid into the measurement chamber. A piston is arranged in the measurement chamber. A sensor generates a voltage which is a measure of a piston travel. The sensor is connected with an evaluation unit which continuously detects the piston travel in the measurement chamber. A rotary displacement pump arranged in a bypass channel to the measurement chamber is driven dependent on an existing volume difference. A pressure sensor is arranged in the measurement chamber. A heating element and/or a cooling device is/are arranged at the measurement chamber and is/are actuated by a controller so that an amount of energy introduced by the fluid injected by the injection valve and an amount of energy introduced by the heating element and/or the cooling device is substantially constant for every injection.

  • Patent number: 7254993
    Abstract: The invention relates to a device for measuring time-resolved volumetric throughflow processes, especially injection process in internal combustion engines, having a translational volume difference sensor having a piston disposed in a measuring compartment and a detection device detecting the excursion of the piston, the detection device being linked with an evaluation unit. According to the invention, a pressure sensor is mounted in the measuring compartment in addition to the detection device which detects the excursion of the piston. The signal of the detection device corresponding to the excursion of the piston can be better evaluated as the compressivity of the fluid in the measuring compartment can be taken into consideration for the calculation of the amount to be injected. The inventive device allows for a highly time-resolved representation of throughflow processes so that both overall amount and exact course of the throughflow can be represented and evaluated.

  • Patent number: 4507021
    Abstract: An arcuate or circular profile element of generally V-shaped cross-section has a curved bottom wall, arcuate sidewalls having free edges, and laterally projecting flanges projecting from the free edges. By choosing specific relationships between the thickness of the different parts of the element, lighter-weight elements can be used to withstand the same loads as before, or elements having the same weight as before can be used to support heavier loads.
