TM 5-3895-373-201.16.TURBOSUPERCHARGER.The turbosupercharger is designed to increase theoverall efficiency of the engine. Power to drive theturbosupercharger is extracted from the waste energy inthe engine exhaust gas.The turbosupercharger consists of a wheel housing,turbosupercharger housing and impeller housing. Thewheel housing, which encloses the turbosuperchargerhousing provides an ambient air inlet and a compressedair discharge outlet connected to the intaketurbosupercharger manifold. The centerturbosupercharger housing has a radial inward flowcompressor wheel, impeller shaft, and center lubricationconnections for oil inlet and oil outlet fittings. Theturbosupercharger housing serves to support the rotatingassembly, bearings, and seals. The impeller housingconsists of the exhaust gas outlet and provides themounting surface to the exhaust manifold.The turbosupercharger receives air from the air cleanerto the ambient air inlet. The power of the exhaust gasdrives the impeller shaft inside the impeller housing.This force is transmitted to the turbosuperchargerhousing where air is drawn through the ambient air inletand compressed. The compressed air flows out of theturbosupercharger housing into the compressed airdischarge outlet, and into the intake manifold on theengine.Lubricating oil for the turbosupercharger is suppliedunder pressure through the engine oil adapter plate.From the adapter plate, the oil flows into an oil line whichis connected to the oil inlet on the turbosuperchargerhousing. The oil returns by gravity to the engine oil sumpthrough an external oil line extending from the oil outletinto a drain line and back into the engine.1-20
