Exhaust system (OG) includes exhaust manifolds with three-way catalytic converters, on which oxygen sensors in the exhaust gas are installed (pic. 5.25), mufflers (front, middle, additional) and pipelines with elements of fastening the system to the body.
The exhaust manifold has a flange connection with the engine cylinder head. Oxygen sensors are mounted on the body of the converter. The fastening elements for the system are bolted connections, clamps, retaining rings and rubber shock absorbers, which must be replaced with each disassembly of the system as a whole or replacement of its individual elements.
The structural diagram of the exhaust system after the converters is shown in Figure 5.26.
Integrated engine management system (KSUD) has a closed control system, because The end result of the combustion process is controlled by the amount of residual oxygen in the exhaust gas. The connection between the electronic control unit of the EBU-KSUD and the sensors for the oxygen content in the exhaust gas allows you to accurately dose the amount of fuel supplied, which in turn reduces the emission of toxic components into the atmosphere. Structurally, they are made similar to the sensors installed on the engine «M54».
