The SVO's turbocharger unit consists of five major components as shown above:
1
The ACTUATOR is a spring-loaded diaphram device that senses the pressure in the intake manifold and controls the wastegate's
(see 4) operation.
2
The COMPRESSOR uses a centrifugal (directed away from a center) radial-type outflow. It consists of a cast-aluminum compressor wheel, backplate assembly, and specially designed housing that encloses the wheel and directs the air-fuel mixture through the compressor.
3
The TURBINE uses a centripetal (directed toward a center) radial-type inflow. It is comprised of a high-temperature cast turbine wheel, wheel shroud, and specially designed housing that encloses the wheel and directs the exhaust gas through the turbine.
4
The outlet elbow contains the WASTEGATE ASSEMBLY, which allows a portion of the exhaust gas to bypass the turbine wheel to limit compressor speed (see 1).
5
The CENTER HOUSING supports the compressor and turbine wheel-shaft bearings which contain oil holes for directing lubrication to the
bearing bores and shaft journals.
