Definitions

  • the present disclosure relates to turbochargers for an internal combustion engine. More particularly the disclosure relates to a method of modular construction and assembly of a turbocharger housing.
  • the turbocharger housing is assembled from modules which are fastened to one another using V-clamps, circlips, bolts, clamp load force, or other suitable attachment devices.
  • a turbocharger is a type of forced induction system used with internal combustion engines. Turbochargers deliver compressed air to an engine intake, allowing more fuel to be combusted, thereby boosting the horsepower of an engine without significantly increasing engine weight. Thus, turbochargers permit the use of smaller engines that develop the same amount of horsepower as larger, normally aspirated engines. Using a smaller engine in a vehicle has the desired effect of decreasing the mass of the vehicle, increasing performance, and enhancing fuel economy. Moreover, the use of turbochargers permits more complete combustion of the fuel delivered to the engine, which contributes to the highly desirable goal of a cleaner environment.
  • Turbochargers typically include a turbine housing connected to the exhaust manifold of the engine, a compressor housing connected to the intake manifold of the engine, and a bearing housing coupling the turbine and compressor housings together.
  • a turbine wheel in the turbine housing is rotatably driven by an inflow of exhaust gas supplied from the exhaust manifold.
  • a shaft rotatably supported in the bearing housing connects the turbine wheel to a compressor impeller in the compressor housing so that rotation of the turbine wheel causes rotation of the compressor impeller.
  • the shaft connecting the turbine wheel and the compressor impeller defines an axis of rotation. As the compressor impeller rotates, it increases the air mass flow rate, airflow density and air pressure delivered to the cylinders of the engine via the intake manifold of the engine.
  • the compressor housing, bearing housing, and turbine housing are frequently connected by bolts, although V-clamps or circlips as attaching devices may also be used.
  • Figure 2 is an exploded view of a two stage compressor having modular construction.
