The exhaust manifold has a flange connection with the engine cylinder head. Oxygen sensors are installed on the neutralizer housing. The fastening elements for the system are bolted connections, clamps, retaining rings and rubber shock absorbers, which must be replaced each time the system is disassembled as a whole or its individual elements are replaced.
The design diagram of the exhaust system after the neutralizers is shown in Figure 5.26.

The integrated engine management system (ECMS) has a closed control system, since the final result of the combustion process is controlled by the amount of residual oxygen in the exhaust gas. The connection between the electronic control unit ECU-ECMS and the oxygen content sensors in the exhaust gas allows for precise dosing of 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 M54 engine.
