1.05L REVOTORQ ENGINE

C. 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 ex-

haust 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.

D. Silencer :

The main function of the silencer is to re-

duce 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 silencers are divided into two main groups.

i) Pre silencer with pipe :

ii) Main silencer with pipe

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 spe-

cifically designed such that opposite sound waves

collide to cancel each other out.
