Components :
1. Exhaust Manifold :
The exhaust manifold is mounted on the
cylinder head. The exhaust gases are trapped
out from the engine through the exhaust
manifold.
2. Lambda Sensor :
The oxygen sensor operates on the
principle of galvanic oxygen concentration cell
(Nernst cell) with solid electrolyte (Nernst's
principle). The ceramic sensing element is a
conductor of oxygen ions from a temperature
of 350 C. A heater is integrated on the
sensing element. It is placed into the exhaust
manifold. The sensing element compares the
residual oxygen content in the exhaust gas
with the oxygen content in the reference
atmosphere (air surrounding the sensing
element). This gives an output voltage
between 100mV (lean exhaust gas) to 800mV
(rich exhaust gas), depending on whether the
exhaust gas is lean or rich.
3. Close Coupled Catalytic Converter (CCC) :
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.
Benefits -:
•
Positioned close to the engine exhaust
ports for fast light-off and reduced cold
start emissions.
•
Internally insulated construction design
enables improved durability, reduced heat
rejection and lower noise.
4. Muffler Assy :
To attenuate or muffle the Engine noise
emitted from the vehicle to the surroundings.
