How to tell if a catalytic converter is clogged?
You can find out if your catalytic converter is clogged by checking for an exhaust restriction. To do this, you would need to place the car in neutral gear and rev up to about 3,500 RPM. If there is a significant drop in RPMs compared to the normal driving conditions then it shows that the catalyst has been restricted due to foreign particles.
Why is a catalytic converter important?
The catalytic converter is crucial for your car’s emission control systems. This means that if it breaks down, there will no longer be an efficient way to control the engine’s emissions. Any unburned fuel will be emitted directly into the environment. In turn, this affects your car’s performance and cause loss of power by causing carbon buildup.
What to check if your car is losing power?
If you are driving and suddenly notice your car is losing power, the first thing to check is your catalytic converter . Catalytic converters help cars run efficiently by converting harmful gases like nitrogen oxide (NO) into less-harmful carbon dioxide (CO2). They also reduce engine emissions that cause smog. In this article, we want to fully answer the question, “Will a clogged catalytic converter cause loss of power?”
What happens when gasoline burns?
When gasoline burns, it creates a byproduct called sulfur dioxide (SO), which finds its way into emissions that are released through the tailpipe. This, in turn, creates sulfuric acid when combined with water and oxygen from the air. Debris can clog up a converter if it gets sucked into an engine’s intake and is burnt along with gasoline during combustion. Even dirt or dust particles that get into the catalytic converter can cause problems for it over time. You should understand that all these issues leading to a clogged catalytic converter eventually makes your car lose power.
Can a clogged catalytic converter cause a car to run?
Yes, a clogged catalytic converter will cause loss of power to your car. A catalytic converter works by converting harmful gases like nitrogen oxide (NO) into less harmful carbon dioxide (CO). If it is clogged, your car will not be able to run efficiently because of insufficient oxygen in the exhaust for adequate combustion. This would result in lower RPMs compared to normal driving conditions.

A clogged catalytic converter results in a loss of power because an engine is aspirated and must breathe; if the restriction is severe enough, the engine may not run.
What is a catalytic converter?
A catalytic converter has an aluminum oxide honeycomb coated with platinum and palladium. These components react to remove CO and HC's from the exhaust stream. A two-way catalytic converter works by oxidizing CO (carbon monoxide) and HC (hydrocarbons "unburned fuel") to CO 2 (carbon dioxide) and water. A three-way catalytic converter also removes NO x (oxides of nitrogen) from the exhaust. NO x is formed at high cylinder temperatures. The EGR or variable valve system inhibits NO x formation.
What is the purpose of a three way catalytic converter?
A three-way catalytic converter also removes NO x (oxides of nitrogen) from the exhaust. NO x is formed at high cylinder temperatures. The EGR system is responsible for inhibiting NO x. When a vehicle is running rich, the catalytic converter is working harder and running hotter than intended.
What happens if a catalytic converter goes bad?
If your catalytic converter went really bad, there is a risk that the catalytic converter is not doing its job properly anymore, and this will cause an increment of the car engine’s emissions. The overall purpose of the catalytic converter is to remove emissions, so this is maybe pretty obvious.

The catalytic converter is located on the exhaust pipe system, between your muffler and the exhaust pipe manifold. Depending on the car model, it is installed at different lengths away from the exhaust pipe manifold. It’s under the hood on some cars, and on other cars, it is located almost in the middle of the car.
Why does a catalytic converter make noise?
It gives harmful substance which directly come from engine exhaust. Also it creates unplesant sound while driving a vehicle. Because when air is coming out from engine exhaust it creates noise which can't reduce by faulty converter.
Why does a catalyst degrade?
The catalyst can also degrade and become dislodged due to excessive vibration, impact, rapid temperature change, or excesive heat. Once the honeycomb is no longer facing with the openings parallel with the exhaust pipe it creates a restriction creating a circumstance like a clog.
Why does my honeycomb catalyst get clogged?
Let's start with the obvious, a clogged catalyst. Engines with significant soot or unburned oil from mechanical wear, poor fuel, and short trip driving that does not allow for the catalyst to heat to operating temperature can allow cause the honeycomb catalyst to become clogged. Exhaust gasses back up causing resistance on the exhaust stroke and subsequently poor intake due to space being taken up by unexpected exhaust gasses, and the motor loses power.
What causes a cat to overheat?
A number of things, including a cylinder that doesn't fire (air and fuel get into the cat and burn there, resulting in an overheated cat), leaded fuel ("poisons" the cat by producing an atom-thick layer of lead over the catalyst), and speed bumps taller than the clearance between the cat and the ground.
What happens when an engine is blocked?
Once blocked the engine becomes less efficient, unable to pass the gases out efficiently. And as such not allowing the engine to breathe. When it can’t breathe it can’t pass the air through fast enough at peak revs . Engines are really nothing more than an air pump . If you stop them sucking in
Is diesel fuel leaded?
The leaded fuel issue is why (car) diesel nozzles are bigger than gas nozzles. No, diesel isn't leaded. Back in the days of leaded gas, gas and diesel nozzles were the same size. When catalytic converters were introduced, unleaded was more expensive than regular, so the government took steps to keep people from "poisoning" cats by using cheaper leaded fuel. They legislated the use of a restrictor plate in the filler neck of cars needing unleaded, and a matching smaller nozzle on pumps dispensing unleaded - the nozzle from a pump dispensing leaded gas wouldn't fit. Since there was no such issue with diesel vehicles (leaded and unleaded gas ruin Diesel engines equally well), they weren't covered by the legislation, and kept the old nozzle size. Leaded automotive gas is no longer allowed in North America, but the legislation is still there even though the need no longer exists.
