2.1.6.1. General information

The final collector settles down behind the engine.

Fig. 2.64. System of production of the fulfilled gases: 1 – main muffler; 2 – average pipe; 3 – three-component catalytic converter; 4 – final collector; 5 – H02S (forward part); 6 – HO2S (back part); 7 – L3 engine


This arrangement allows to use shorter exhaust pipes and to increase efficiency of release. Besides, thanks to the reduced distance to catalytic converter, temperature of the fulfilled gases falls slightly therefore the catalyst works more effectively. Cooling of the fulfilled gases is also prevented by application of two-layer pipes of a final collector (fig. 2.64).
