Operation Manual / TPR56-F + TPR61-F1 Preliminary remarks / 1.2 Layout and function© Copyright 2018 . All rights reserved. HZTL2490_EN Revision D May 2018Mode of operationThe turbocharger is a turbomachine consisting of two main compon-ents, a turbine and a compressor. These components are mounted on acommon shaft and form the rotor.In the turbocharger shown in the illustration, the exhaust gas flowsthrough the gas inlet casing (06) and the nozzle ring (07) and arrives atthe turbine (08). The turbine utilises the energy contained in the exhaustgas to drive the rotor. The exhaust gases then escape into the open airthrough the gas outlet casing (05) and the exhaust gas pipe connectedto it.The rotor runs in two radial plain bearings, which are located betweenthe compressor and the turbine in the bearing bush (04). The axial bear-ing is also a plain bearing. The plain bearings are connected to a centrallubricating oil duct which is normally supplied by the lubricating oil cir-cuit of the engine. The oil outlet is situated at the lowest point of thebearing casing (09).The compressor wheel (02) connected to the shaft draws in fresh airthrough the filter silencer (01) or the air suction branch. The air is com-pressed in the compressor and the downstream diffuser (03) and thenled to the charge air cooler via the compressor casing (10).Page 5 / 79
