System of release of the fulfilled gases

The general information

Models 2.0 and 2.5 l

Design of system of release of the fulfilled gases (models 2.0 and 2.5 l with OBD II)


1 — the Right reception pipe 2 — the Left reception pipe 3 — Forward каталитический the converter 4 — the Dokatalitichesky ljambda-probe 5 — the Postkatalitichesky ljambda-probe	6 — the Central pipe 7 — Back каталитический the converter 8 — the Resonator 9 — Back section 10 — the Muffler

Design of system of release of the fulfilled gases (models 2.0 and 2.5 l with OBD Subaru, equipped catalytic the converter)


1 — the Right reception pipe 2 — the Left reception pipe 3 — Forward каталитический the converter 4 — the Ljambda-probe 5 — the Central pipe	6 — Back каталитический the converter 7 — the Resonator 8 — Back section 9 — the Muffler

Design of system of release of the fulfilled gases (models 2.0 and 2.5 l with OBD Subaru, without каталитического the converter)


1 — the Right reception pipe 2 — the Left reception pipe 3 — the Central pipe	4 — the Resonator 5 — Back section 6 — the Muffler

On models 2.0 and 2.5 l the final path consists of assemblage of reception pipes, каталитических converters (at a corresponding complete set), the central pipe, back section and the muffler. Forward каталитический the converter fastens directly to reception assemblage, back is built in in a back part of the central section. For the purpose of decrease in level of a noise background the point of connection of reception pipes of forward section of system of release is located on equal removal from final ports of the engine, and in a back part of system, besides the 16-litre muffler resonators (on latest models of 2.5 l are equipped by resonators also both receptions of a pipe) are established.

L models 3.0

Design of system of release of the fulfilled gases (model 3.0)


1 — Right докаталитический a ljambda-probe 2 — Left докаталитический a ljambda-probe 3 — the Right reception pipe 4 — the Left reception pipe 5 — Right forward каталитический the converter 6 — Left forward каталитический the converter	7 — Back каталитический the converter 8 — the Postkatalitichesky ljambda-probe 9 — the Resonator 10 — Back section 11 — the Muffler

Design of the muffler with a variable direction of a stream


1 — Small turns of the engine	2 — High turns of the engine

The design of system of release of the fulfilled gases is presented on an illustration.

Distinctive feature of system of release on l models 3.0 is use of the muffler equipped with the special valve-switch with a variable direction of the stream considerably reducing level of a noise background published by the engine.
