In most cases these are or have been trademarks that a particular manufacturer has used with reference to their product. There are a number of different acronyms that are commonly used when referring to turbochargers with variable geometry turbines. Pivoting vane (left) and moving wall (right) variable geometry turbochargersġ. These designs will be discussed in more detail in the following sections. Others include the variable area type, variable flow type and the sliding ring designs. Two of the more common ones are the pivoting vane and moving wall types, Figure 1. Since that time, a number of different designs have appeared. The idea of using a variable geometry turbine in a turbocharger dates back at least to the 1950s. ability to raise exhaust temperature for aftertreatment system management.a better ability to cover a wider region of low BSFC in the engine speed–load domain.control over engine ΔP that can be used to drive EGR flow in diesel engines with High Pressure Loop (HPL) EGR systems.potential for lower engine ΔP (the difference between exhaust manifold and intake manifold pressures).improved vehicle accelerations without the need to resort to turbines with high pumping loss at high engine speeds. ![]() higher air–fuel ratio and higher peak torque at low engine speeds.no throttling loss of the wastegate valve.The benefits of variable geometry turbines over wastegated turbines include : Variable Geometry Turbines for SI EnginesĪn alternative to the fixed geometry turbine is the variable geometry turbine.Applications of Variable Geometry Turbochargers.The most common designs of variable geometry turbochargers include the pivoting vane design and the moving wall design. In diesel engines, this flexibility can be used for improving low speed torque characteristics, reducing turbocharger lag and driving EGR flow. Abstract: The variable geometry turbine allows significant flexibility over the pressure ratio across the turbine. ![]()
