Abstract:
1. A method of making an engine assembly, comprising: a cylinder head having an exhaust port and an exhaust port mounting flange disposed proximate the exhaust port; a turbocharger having a turbine, the turbine having a turbine housing, the turbine housing comprising a turbine inlet and turbine outlet, the turbine inlet configured to receive an exhaust flow from the exhaust port and fluidly communicate the exhaust flow through the turbine housing to the turbine outlet, the turbine inlet comprising a turbine inlet mounting flange that is removably mounted on and in sealed engagement with the exhaust port mounting flange, the turbine outlet comprising a turbine outlet mounting flange; an exhaust conduit, the exhaust conduit comprising an exhaust conduit inlet, the exhaust conduit inlet configured to receive the exhaust flow from the turbine outlet, the exhaust conduit inlet comprising an exhaust conduit inlet mounting flange that is removably mounted on and in sealed engagement with the turbine outlet flange; a first assembly aid disposed between the exhaust conduit and the cylinder head; a second assembly aid axially disposed between the turbine housing proximate the turbine outlet and the exhaust conduit proximate the exhaust conduit inlet and configured to provide alignment of the turbine outlet mounting flange and exhaust conduit inlet mounting flange; a third assembly aid disposed circumferentially about and configured to provide nested engagement of the turbine outlet and the exhaust conduit inlet; and a clamp configured for sealing attachment of the exhaust conduit inlet mounting flange to the turbine outlet mounting flange, wherein the first assembly aid comprises a joint between the cylinder head and the exhaust conduit, the second assembly aid comprises a first joint between the turbine and the exhaust conduit and the third assembly aid comprises a second joint between the turbine and the exhaust conduit; using a single human assembler, comprising: removably and sealably mounting the turbine inlet mounting flange to the exhaust port mounting flange; using the first assembly aid to form a slidable joint and dispose the exhaust conduit on the cylinder head; using the second assembly aid to form a movable joint between the turbine housing and the exhaust conduit and movably align and dispose the turbine outlet mounting flange on the exhaust conduit inlet mounting flange; using the third assembly aid to pilotingly engage the turbine outlet mounting flange and the exhaust conduit inlet mounting flange; circumferentially disposing the clamp about the turbine outlet mounting flange and the exhaust conduit inlet mounting flange; tightening the second assembly aid sufficiently to form an immovable joint between the turbine housing and the exhaust conduit; tightening the clamp to form a sealed joint between the turbine outlet mounting flange and the exhaust conduit inlet mounting flange; and tightening the first assembly aid to form a fixed joint and dispose the exhaust conduit on the cylinder head.
