Embodiments of the present invention relate to a control device for an internal combustion engine. The control device controls an internal combustion engine 10 that includes a throttle valve and a TCV. The control device selectively implements a stoichiometric mode that causes the internal combustion engine to operate in a stoichiometric region, and a lean mode that causes the internal combustion engine to operate in a lean region. The control device executes a process that places the TCV in a closed state for generating a tumble flow, and a process that places the TCV in an open state for suppressing a tumble flow. A process that switches the TCV from the open state to the closed state is executed during implementation of the lean mode.

A hollow portion (23) through which a rotation member (19) rotatably penetrates is formed in an intake manifold (10) which is a nonmagnetic member. A magnet holding portion (27) which holds the magnet (26) is inserted into the hollow portion (23) from the opening end portion (25)'s side. A position sensor (22) is assembled to a retaining portion (30) formed on an outer circumference portion of the hollow portion (23). A cover (35) is spin-welded to close the opening end portion (25) in a state where the magnet holding portion (27) and the position sensor (22) are assembled. This cover (35) restricts the movements of the magnet holding portion (27) and the position sensor (22) in a rotation axis direction.

The invention relates to a flow body (4) which, arranged in an inlet (3) of an internal combustion engine, permits a diversion of the air flowing through the inlet (3) and/or of the fuel-air mixture as it passes from the inlet (3) through an inlet opening (2) into a combustion chamber (1). The invention also relates to a masking module (8) having the flow body (4) and to an internal combustion engine having at least one combustion chamber (1) and having an inlet opening (2) to the combustion chamber (1), which inlet opening can be closed and opened by an inlet valve (2), wherein the combustion chamber (1) is assigned a duct-like inlet (3) for air and/or a fuel-air mixture, in which inlet is arranged a flow body (4) and/or a masking module (8).

Die Erfindung betrifft eine Klappenvorrichtung (2) für eine Sauganlage (1) einer Brennkraftmaschine, insbesondere eine Kraftfahrzeugs, mit einem Gehäuse (5), das genau einen Einlasskanal (6) je Zylinder der Brennkraftmaschine aufweist, und mit einer Klappenanordnung (7), die für jeden Einlasskanal (6) eine Klappe (8) zum Verändern des durchströmbaren Querschnitts des jeweiligen Einlasskanals (6) aufweist. Eine vorteilhafte Bauform lässt sich erreichen, wenn die Klappenanordnung (7) für alle Klappen (8) eine gemeinsame Betätigungswelle (13) zum gemeinsamen Verschwenken der Klappen (8) um die Klappenschwenkachse (12) aufweist, die Betätigungswelle (13) einen Magnetträger (43) drehfest trägt, der seinerseits einen Permanentmagneten (44) trägt, der mit einem Drehwinkelsensor (32) zur Drehlagenerkennung der Klappenanordnung (7) zusammenwirkt, und das Gehäuse (5) zwischen dem Permantmagneten (44) und dem Drehwinkelsensor (32) einen Wandabschnitt (46) aufweist.
摘要:
Provided is an operational rod coupling arrangement that can be comprised of fewer number of parts and that allows easy assembly. Provided also is a connecting member for use in the coupling arrangement. The arrangement includes a motion member constituting a portion of a motion mechanism, an operational rod having a coupling hole at an end thereof to be pivotally coupled with the motion member for transmitting an operational force thereto and a connecting member configured to clamp the end of the operational rod in cooperation with a portion of the motion member. One of the motion member and the connecting member includes a shaft portion and the other one of the motion member and the connecting member includes a bearing portion in which the shaft portion can be inserted. The shaft portion, as extending through the coupling hole of the operational rod, can be inserted into the bearing portion. An engaging portion and an engaged portion for preventing withdrawal of the shaft portion from the bearing portion are provided at different positions than the shaft portion and the bearing portion in the connecting member and the motion member, respectively.
