Components :

a) Closed Coupled Catalytic Converter :

The Close Coupled Catalytic Converter is a critical

element of the system used to reduce vehicle

exhaust emissions. The catalytically active

element within the converter lowers the activation

energy needed to selectively transform harmful

combustion products into less harmful gases. The

catalyst becomes active when it reaches a

threshold temperature.

Close coupled Catalytic Converter is physically

positioned very close to the engine exhaust ports

to enable quicker light-off. It also enables flushing

out of the carbon particles present in the Catalytic

Converter.

Benefits :



Positioned close to the engine exhaust ports

for fast light-off and reduced cold start

emissions



Robust construction offers excellent durability.

Internally insulated construction design enables

improved durability, reduced heat rejection and

lower noise.

b) Silencer :

The function of silencer is to reduce exhaust

noise. The silencers are divided into three main

groups.

Pre-silencer :

ii.

Main silencer :

iii.

Post silencer :

The main function of the silencer is to reduce the

amount of noise emitted by the engine exhaust

gases flow. It typically makes use of the change in

the cross sectional area which can be made as a

chamber to filter or reduce the sound waves which

the engine produces.

The silencer is typically installed along the

exhaust pipe as part of the exhaust system of the

engine. It has a resonating chamber, which is

specifically designed such that opposite sound

waves collide to cancel each other out.

c) Exhaust Manifold :

The exhaust manifold has a precisely machined

hole through which the exhaust gases are tapped

out.
