Abstract
A guide element for a pressure system of an internal combustion engine has a hollow body with a guide element inlet (27), a guide element outlet (28) and a longitudinal axis (26). The guide element (25) is designed so that flow can pass through it along its longitudinal axis (26). To eliminate disruptive oscillations, the guide element (25) is of streamlined form in a flow direction from the guide element inlet (27) to the guide element outlet (28). A pressure system for an intake tract of an internal combustion engine and an internal combustion engine with a supercharging unit also are provided.
Claims23
A guide element for a pressure system of an internal combustion engine, comprising a hollow body with a guide element inlet, a guide element outlet and a longitudinal axis, the guide element being configured so that a flow can pass through the hollow body along the longitudinal axis, the guide element being of streamlined form in a flow direction proceeding from the guide element inlet to the guide element outlet to eliminate disruptive oscillations, areas of the hollow body adjacent the guide element outlet defining a cylindrical section having a guide element outlet diameter, an outwardly curved flared section extending along the hollow body from the cylindrical section to the guide element inlet, the guide element inlet having a guide element inlet diameter, the guide element outlet diameter has a value of at least 0.3 times the guide element inlet diameter and at most 0.5 times the guide element inlet diameter.
A pressure system for an intake tract of an internal combustion engine with a distributor pipe, through which flow can pass, the distributor pipe having a flow inlet and a flow outlet, a collector tank of the pressure system being arranged at the flow outlet, the collector tank having a tank inlet connected to the flow outlet and further having a tank outlet connected by way of a primary pipe of the pressure system so that flow can pass through to a cylinder of the internal combustion engine;
- and a guide element having a hollow body with a guide element inlet, a guide element outlet and a longitudinal axis, the guide element being configured so that a flow can pass through the hollow body along the longitudinal axis and being of streamlined form in a flow direction proceeding from the guide element inlet to the guide element outlet to eliminate disruptive oscillations, wherein the guide element is arranged at the flow outlet or between the flow inlet and the flow outlet of the distributor pipe, downstream of a branching point of the distributor pipe.
A pressure system for an intake tract of an internal combustion engine with a distributor pipe, through which flow can pass, the distributor pipe having a flow inlet and a flow outlet, a collector tank of the pressure system being arranged at the flow outlet, the collector tank having a tank inlet connected to the flow outlet and further having a tank outlet connected by way of a primary pipe of the pressure system so that flow can pass through to a cylinder of the internal combustion engine;
- and a guide element having a hollow body with a guide element inlet, a guide element outlet and a longitudinal axis, the guide element being configured so that a flow can pass through the hollow body along the longitudinal axis and being of streamlined form in a flow direction proceeding from the guide element inlet to the guide element outlet to eliminate disruptive oscillations, wherein the guide element outlet diameter has a value of at least 0.3 times the diameter at the flow inlet of the distributor pipe and at most 0.5 times the diameter at the flow inlet of the distributor pipe.
