Abstract: A turbocharger includes a turbine housing including an interior surface defining a turbine housing interior. The interior surface extends between a turbine housing inlet and a turbine housing outlet. The turbine housing also includes a wastegate duct disposed downstream of the turbine housing inlet and defining a wastegate channel. The turbocharger also includes a valve seat disposed about the wastegate channel, with the valve seat having a valve seat plane extending along the valve seat. The turbocharger further includes a wastegate assembly including a valve element engageable with the valve seat. The wastegate channel extends along a channel axis, and the channel axis is obliquely oriented with respect to the valve seat plane such that the wastegate channel and the valve element are configured to direct exhaust gas to a catalytic converter.

Abstract: A wastegate assembly includes a valve arm moveable between a first position and a second position to control flow of exhaust gas to a turbine housing interior of a turbocharger. The valve arm includes a proximal end, a distal end spaced from the proximal end, and a valve arm orientation projection spaced from the distal end and extending away from the proximal end. The wastegate assembly also includes a valve body coupled to the distal end of the valve arm that is moveable with the valve arm. The valve body includes a valve body orientation component, and the orientation projection of the valve arm extends toward and is orientable with the orientation component of the valve body to orient the valve arm relative to the valve body. The valve body is disposed between the orientation projection of the valve arm and the distal end of the valve arm.

Abstract: A connecting assembly includes an actuator connecting rod defining a rod aperture, configured to be coupled to an actuator, and moveable between first and second rod positions by the actuator. The connecting assembly also includes a lever arm coupled to the actuator connecting rod, defining a lever aperture, configured to be coupled to a wastegate valve, and moveable between first and second arm positions by the actuator connecting rod. The connecting assembly further includes a pin having a first pin portion disposed in one of the rod and lever apertures and having a first diameter, a second pin portion disposed in the other of the rod and lever apertures and having a second diameter larger than the first diameter, and a third pin portion having a third diameter larger than the first and second diameters to allow pivotable movement between the actuator connecting rod and the lever arm.
