  • Volumetric Efficiency and Pumping Torque Estimation and Compressor Recirculation Control of Turbocharged Engines (.pdf)
    This paper presents three sub-models of production Engine Management Systems software for turbocharged engines; 1) new load variable for volumetric efficiency modelling, 2) new pumping torque model, where 1) and 2) both solve non-monotonic behavior of traditional techniques for active boost
  • Blackmer C-Series Mouvex Principle Eccentric Disc Sealless Pump Technology
    , the global demand for highly reliable pumps that can eliminate leaks, provide gentle handling of liquids and provide high volumetric efficiencies and economic advantages has substantially increased. Eccentric disc technology pumps are uniquely qualified to meet all of these demands. (Figure 1). Key Design
  • A Mean-Value Model for Estimating Exhaust Manifold Pressure in Production Engine Applications (.pdf)
    A key quantity for use in engine control is the exhaust manifold pressure. For production applications it is an important component in the calculation of the engine volumetric efficiency, as well as EGR flow and residual fraction. For cost reasons, however, it is preferable to not have to measure

    competitiveness and viability. Sliding vane technology is being used worldwide to reduce energy costs and consumption, and create a more efficient pumping system. While world-renowned for its ability to offer increased suction, reduced product shear and consistent volumetric efficiency, sliding vane
  • Fluid Motors
    , the shaft is driven through a differential-gear arrangement that permits low speed and high torque. Axial-piston motors have a reputation for high volumetric efficiency, combined with excellent operation at both high and low speeds. In hydraulic designs, axial-piston motors produce maximum torques
  • When to Use PD Pumps (Copyright Viking Pump, Inc.)
    on the capacity of the pump. You will notice in the flow rate chart how the centrifugal pump loses flow as the viscosity goes up but the PD pump's flow actually increases. This is because the higher viscosity liquids fill the clearances of the pump causing a higher volumetric efficiency. Remember
  • Fluid Performance Factors
    be penalized harshly by pump cavitation and sluggish response of critical actuators. Low-viscosity fluids permit efficient low-drag operation, but tend to increase wear, reduce volumetric efficiency, and promote leakage. In theory, this leakage can be predicted on the basis of fluid viscosity
