1.16. TURBOSUPERCHARGER

TM 5-3895-373-20 1.16. TURBOSUPERCHARGER. The turbosupercharger is designed to increase the overall efficiency of the engine. Power to drive the turbosupercharger is extracted from the waste energy in the engine exhaust gas. The turbosupercharger consists of a wheel housing, turbosupercharger housing and impeller housing. The wheel housing, which encloses the turbosupercharger housing provides an ambient air inlet and a compressed air discharge outlet connected to the intake turbosupercharger manifold. The center turbosupercharger housing has a radial inward flow compressor wheel, impeller shaft, and center lubrication connections for oil inlet and oil outlet fittings. The turbosupercharger housing serves to support the rotating assembly, bearings, and seals. The impeller housing consists of the exhaust gas outlet and provides the mounting surface to the exhaust manifold. The turbosupercharger receives air from the air cleaner to the ambient air inlet. The power of the exhaust gas drives the impeller shaft inside the impeller housing. This force is transmitted to the turbosupercharger housing where air is drawn through the ambient air inlet and compressed. The compressed air flows out of the turbosupercharger housing into the compressed air discharge outlet, and into the intake manifold on the engine. Lubricating oil for the turbosupercharger is supplied under pressure through the engine oil adapter plate. From the adapter plate, the oil flows into an oil line which is connected to the oil inlet on the turbosupercharger housing. The oil returns by gravity to the engine oil sump through an external oil line extending from the oil outlet into a drain line and back into the engine. 1-20
