1.5L REVOTORQ ENGINE



No foreign particles (dust/dirt) should enter the

vacuum line.



Ensure the conditions of handling and installa-

tion of turbocharger/manifold are such that there

is no risk of shocks, dropping the turbocharger or

damage to the sealing surfaces (turbine housing

inlet and outlet surfaces, compressor inlet and

outlet, oil circuit), or damage to the actuator or

flow adjusting rod and screw which might lead to

the misalignment.



If the turbocharger is dropped, then it should be

inspected. If it is damaged, it should not be used.



Put few drops of oil during assembly and rotate

the wheel with finger. Look for free movement of

wheel with no wheel rubbing.

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 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.

D. Silencer

The main function of the silencer is to reduce the

amount of noise emitted by the engine exhaust

gases that flow out. 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) Exhaust Pipe Assy. with Pre-silencer

ii) Exhaust Assy., Rear (Main Silencer)

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 de-

signed such that opposite sound waves collide to

cancel each other out.
