converter unlimited engine is part of the exhaust system and is located in the immediate vicinity of a vehicle’s exhaust manifold.
converter unlimited enters into that incandescent exhaust manifold, and after that, significantly slowed down,
cooled and cleaned of harmful substances, it appears in a resonator and in a muffler.
The principle of operation of a catalyst is based on chemical reactions that neutralize harmful emissions of nitrogen oxide, carbon,
and all kinds of hydrocarbon groups.
main element of a converter unlimited
The main element of a converter unlimited is made in a form of a massive ceramic or metal block with small honeycombs,
on walls of which precious metals are applie:
an alloy of iridium and platinum, as well as rhodium and palladium.
When touching chemically active surfaces, harmful compounds are burne and remove from the exhaust pipe in the form of harmless N2 and CO2.
Platinum and palladium act as oxidants in a catalyst and greatly accelerate the combustion of hydrocarbons.
The active element is place in a metal casing and provide with a layer of thermal insulation.
converter unlimite not only traps and neutralizes harmful compounds but also directly affects the operation of an engine.
Signals from sensors locate at the input and output of a catalyst are constantly read by the “brains” of a car and help to optimize working mixture in the best way.
It is better to know in advance all possible reasons for a malfunction to avoid engine and vehicle damage.
converter unlimited malfunction symptoms
The service life of an expensive converter unlimited is usually about the same as the service life of the entire car,
but it often breaks down much faster than it should be and can pull the engine with it.
It is important to remember that a converter unlimited does not fail for no reason.
Its breakdown is a sign of improper operation of the ignition system, incomplete combustion of a mixture in cylinders, severe engine wear, or prolonged use of low-quality fuel.
You can understand that your converter unlimite is being scrappe by several characteristic symptoms:
– the decrease in motor performance;
The most common symptom of a catalyst failure is a severe decrease in engine power. The car starts to lose momentum and accelerates poorly.
Engine runs unstable, overheats, and stops. This happens when the throughput of a converter unlimite is greatly reduced:
the honeycomb is destroye, melte and sintere, clogging the hole and interfering with the free passage of exhaust gases.
At the initial stage of such converter unlimited malfunction, the car will accelerate to a relatively low speed, the engine starts hard,
and then “suffocate” and stall. Fuel efficiency also deteriorates markedly. Also, during a cold start, a strong unpleasant odor appears.
– rumble under the bottom;
A loud rumble under the underside of a car indicates that the active element of a catalyst has begun to deteriorate and fall apart.
Ceramic converter unlimited fragments affected by exhaust gas flow randomly beat against walls of a casing and create an unpleasant rumble.
As a rule, this is most clearly manifested at increased engine speeds and during start-up.
– low pressure of exhaust gases from a muffler
If you bring your hand to an exhaust pipe, you can feel a pulsation. Exhaust valves of cylinders work alternately.
If the exhaust flow is even and constant at idle, this is a sure sign of a clogged converter unlimited.
If you increase the speed and then turn off the engine, exhaust gases will continue to build up pressure for a short time,
gases accumulated in the clogged converter unlimited pipe come out.
