US 2020/0131998 A1 · CONTROL DEVICE FOR AN INTERNAL COMBUSTION ENGINE

Abstract

A control device for an internal combustion engine includes an intake channel with an inlet and an outlet, a control element, an exhaust gas recirculation channel with an opening, a recirculation channel, and a shaft having the control element eccentrically mounted thereon. The exhaust gas recirculation channel enters the intake channel. The opening of the exhaust gas recirculation channel is a valve seat for the control element. The shaft acts as an axis of rotation for the control element. A rotation of the shaft moves the control element between a first end position where the control element throttles the intake channel and a second end position where the control element contacts the valve seat at the opening of the exhaust gas recirculation channel. The axis of rotation is arranged in a plane which passes through the valve seat at the opening of the exhaust gas recirculation channel.

A control device for an internal combustion engine, the control device comprising:

an intake channel comprising an inlet and an outlet;
a control element;
an exhaust gas recirculation channel comprising an opening, the exhaust gas recirculation channel being configured to enter into the intake channel, the opening of the exhaust gas recirculation channel being configured as a fixed valve seat for the control element in a closing state of the exhaust gas;
a recirculation channel;
and
a shaft on which the control element is eccentrically mounted, the shaft being configured to act as an axis of rotation for the control element;
wherein,
a rotation of the shaft moves the control element between a first end position in which the control element at least throttles the intake channel and a second end position in which the control element contacts the fixed valve seat at the opening of the exhaust gas recirculation channel, and
the axis of rotation is arranged in a plane which passes through the fixed valve seat at the opening of the exhaust gas recirculation channel.
