Why is a stronger needed in a car exhaust system?

Hello, dear friends! I would like to study in more detail such an issue as replacing the catalyst with a flame arrester. Many people strive to carry out such a procedure, sometimes without understanding what it can lead to.

But I will try to be as objective as possible. I will tell you not only about the consequences, but also about what positive aspects arise when replacing the standard catalyst in the exhaust system of a car with a flame arrester or stronger. This is the same concept, but it is the flame arrester that is most widespread among car enthusiasts.

This is not to say that this is a universal element that can be installed always and everywhere. We need to understand this issue and get the most important answers.

Correct installation of a stronger, selection, pros and cons.

Hello dear guests and customers of our online store!
In this article we will try to give you answers to questions such as:

- pros and cons of this device

In such cases, it is the stronger that helps solve this kind of problem. The spare part itself is a barrel with pipes on the sides; inside there is a pipe with gill-shaped holes twisted in a spiral and also a filler in the cavity of the tank. The essence of the stronger's work is that it takes on all the excess exhaust gases during sharp acceleration and thereby reduces the pressure in the system. This in turn leads to a more balanced exhaust operation.

— stronger 550 mm from 3 liters and above.

Of course, it wouldn’t hurt to estimate the size of the stronger right away on the car so that it fits with its dimensions.

As a rule, a stronger is installed instead of a catalyst that has become unusable. If the catalyst is working, then the stronger can be welded after it, in front of the resonator, or in place of the resonator (if there is none). You should not install the stronger further than the middle of the exhaust, as this will not bring you much effect.

Stronger is made of aluminized steel, excellent for welding with both electrode and TIG, MIG welding.

Another important point that you should pay attention to when installing this spare part is which side to put it on. After all, there is a significant difference.

If we look inside the stronger, we will see smooth bulges on one side and holes on the other. The holes should be placed towards the main muffler (towards the rear of the car), and the other side towards the engine. Usually the manufacturer marks the side facing the motor with a yellow ribbon.

PROS AND CONS OF STRONGER:

The advantages include:

- improved vehicle dynamics

— reduction of vibration of the exhaust system

- smoother engine operation during acceleration

— if you install the stronger on the wrong side, there will be no effect

— if you install a stronger as a resonator, the sound will not become particularly quieter, since its purpose is different.

Advantages and disadvantages

In conclusion, I propose to look at the pros and cons, that is, at the possible negative and positive consequences if you replace the standard catalyst with a not quite standard flame arrester.

What is a stronger?

Installing additional elements that can optimize the performance of the exhaust system has become quite popular in recent years.
Such modernization is carried out not only on domestic cars, but also on foreign cars of different brands. You can often find the installation of new equipment instead of a catalyst (flame arrester or stronger), or the addition of a muffler corrugation to reduce oscillatory processes in the exhaust system, etc. Today we will focus on the topic, stronger - what it is, what function it performs, and why it is installed in the exhaust system.

Stronger, what is this?

A stronger is a part installed in the exhaust system of a car, which serves to optimize its operation. The part consists of two pipes of the same diameter, inlet and outlet, and a working part of a larger diameter. The working part of the stronger consists of a cylinder, inside of which you can see blades arranged in a spiral.

This product must be correctly installed in the exhaust system, since the location of the blades must be in the direction of the flow of exhaust gases. The diameter of the pipes should be the same as that of the connecting pipes of the exhaust system.

Stronger, what is it for?

Stronger, due to the spiral arrangement of the blades inside the working area, is able to spin and accelerate the exhaust gas stream.
This approach allows for better conductivity of exhaust gases along the muffler system path, as well as reducing the effect of the backflow phenomenon. Counterflow is the back pressure of exhaust gases that occurs in the exhaust system. As a rule, the counterflow effect is seriously enhanced by the catalyst at the initial level and the muffler at the end of the exhaust tract. Stronger is able to somewhat reduce the effect of this phenomenon.

Backflow is directly related to a decrease in net engine power. You may ask why a stronger is needed if the exhaust system has a muffler that will still extinguish the stream of exhaust gases accelerated by the stronger? It is not that simple!

The point here is the stronger's shoulder blades, or rather their location. On the one hand, the blades twist and accelerate the stream of exhaust gases, and on the other hand, they slow down the movement of exhaust gases moving in the opposite direction (counterflow). They are a physical barrier to counterflow due to their structural features, and inhibit its action.

And so let’s summarize what a stronger is needed for:

I hope we helped you answer the question of why this part is needed in the muffler system. However, it is still worth dwelling on the topic of where to install it.

Stronger instead of a catalyst, stronger or resonator

Already in the title of this subheading we indicated where the stronger is most often installed. Let's consider both cases.

Stronger instead of a catalyst.

In this case, a stronger is installed instead of a catalyst. There are two ways to do this:

In the second case, the stronger is welded into the catalyst body:

Problems with the second oxygen sensor (catalyst) can be solved by installing a fake lambda probe, or by flashing the engine control program.

Stronger or resonator.

A stronger is often installed instead of a resonator, or as an additional and independent element of the exhaust system. We recommend installing the stronger separately, since the resonator and the stronger perform different functions.

The resonator acts as a primary muffler and is responsible for partial compensation of sound vibrations. It is especially effective for the low peak frequency range. If the resonator is removed from the car, you may have problems with increased engine noise, especially at higher speeds.

Stronger performs the role of optimizing the operation of the exhaust, and is not responsible for compensating for sound waves, although when a sound wave hits it, it is subject to additional damping through crushing.

Installing a stronger in front of the resonator will improve engine performance, because will reduce the effect of countercurrent. Stronger, instead of a catalyst, plays exactly the same role.

Since there was already a topic about replacing the catalyst. Then let’s look at what types of catalysts there are, which catalyst is more important to replace? How many of them are there and what does it depend on? Also, what is a flame arrester, its purpose, how it is installed and its composition. The car exhaust system has two types of catalyst.

The first catalyst is located in the exhaust manifold block (photo No. 1); as a rule, it is replaced with a stainless steel collector flame arrester (steel wool) with ceramic fiber packing. It is inserted into the manifold body instead of the removed catalyst and scalded.

Second mainline catalyst "Doge"

"smoking" is responsible for the environment (affects toxicity - smell in the cabin). After removal, it is replaced with a universal type stronger.

The universal stronger AWG Polonez differs from each other only in diameter and length, standard factory sizes (D45mm, D50mm, D55mm, D60mm, length L300mm, L400mm, L550mm). After removing the two catalysts and replacing them with a flame arrester and a stronger , the exhaust manifold and exhaust pipe assembly is installed back under the car. In what cases are collector and universal stronger flame arresters installed? The collector (exhaust) catalyst is designed to dampen the temperature of the exhaust gases and reduce their resonance. If over time it fails, it is not necessary to change the entire collector, you can limit yourself to a collector flame arrester (photo No. 2).

The flame arrester acts as a primary resonator and also effectively reduces the temperature of the exhaust gases. The dimensions of flame arresters depend on the engine power and have different diameters, lengths and pipe diameters, which affect the throughput. For example, the diameter of the pipe is 57mm, the length is 100mm, the diameter of the barrel is 100mm, the wall thickness is 1.5mm. Manifold flame arresters are installed in the exhaust manifold housing, and strongers are installed instead of free-standing catalysts, which are located on a straight line or exhaust pipe. If you do not have the first catalyst (manifold flame arrester) , which is designed to dampen the temperature of the exhaust gases, the exhaust system will fail faster .

What determines the number of catalysts and their size?

The number of catalysts depends on the number of cylinders. Four cylinder engines have one or two catalysts. On modern cars, one catalyst is always located immediately after the manifold or combined with it.

Design and material of the collector flame arrester

The principle of operation of a collector flame arrester is similar to a resonator. In the usual case, this is a pipe of small (different) diameters with perforations for gases, inserted into a steel casing. A heat-resistant filler is laid between the body and this pipe. Two layers: stainless steel wool and ceramic fiber, they additionally dampen sound waves. The collector flame arrester has an inlet and an outlet (pay attention during installation), the end sides are tightly wrapped. This design has diffusers (funnels) designed to more effectively reduce the speed of the gas stream.

Pros and cons of a stronger in the exhaust system

The first advantage is saving your budget; the stronger is installed as an alternative to a very expensive catalyst. The second plus is that if a stronger is installed, then if you fill up with bad gasoline, the catalyst will be in good working order. The third plus is that the stronger has a direct-flow structure, unlike a catalyst with a dense honeycomb. In the future, this contributes, although not greatly, to an increase in engine power.

One of the downsides, and you can’t live without them, is environmental pollution. Exhaust gases are not cleaned and escape into the atmosphere (smell and soot may appear in the cabin). Another disadvantage is that the load on the muffler components located behind the stronger (resonators, rear banks, muffler pipes) increases; they are exposed to high temperatures. Here are the pros and cons of replacing the catalyst with a flame arrester. There are still more advantages, but it’s definitely up to you to decide whether to install a cheap original catalytic converter unit (catalyst) or a flame arrester.

What else do you need to know when installing a stronger?

Some cars have devices (oxygen sensors or lambda probes) to take readings of the purified gases released from carbon dioxide (CO2). If you remove the catalyst from the system, the sensors will incorrectly adjust the fuel supply. In this case, it is necessary to install a mechanical decoy for the lambda probe, or reprogram the engine control unit to Euro-2 standards, in other words, flash it or do chip tuning.

Why do they replace?

I won’t tell anyone a secret if I say that the decision to replace the catalyst with a flame arrester is largely due to the economic component. That is, the car owner simply wants to save money.

Just look at the cost of this element. If we take into account even domestic cars, the price tag will look impressive. Now imagine that your VAZ has already covered about 200-300 thousand kilometers. And here the need arises to change the catalyst. Such a purchase will cost 50-70 thousand rubles. Agree, the amount is more than serious. And compare it with the cost of a flame arrester, the price of which is several times less. Some even make it with their own hands from a piece of pipe, making many holes in it. Then the price will be completely zero.

If you decide to install such a design for yourself, do not forget about the mandatory equipment of a stronger with blende. Decoy, catalyst emulator, lambda decoy. Call it what you want. This will not change the essence.

The lambda decoy serves to correct the incoming signal from the oxygen sensor to the electronic control unit of your car. Moreover, it is necessary to install such a device if a flame arrester is installed in place of the catalyst.

Without doing this, the ECU will begin to perceive the operation of the exhaust system as problematic, and the emergency mode of operation of the internal combustion engine will begin to constantly turn on. This will result in a decrease in engine life and an increase in fuel consumption.

Similar designs, made from stronger and blende, can be installed on any car:

Our works

Stronger (flame arrester) is a part of the exhaust system responsible for reducing the temperature and speed of exhaust gases. This facilitates the functioning of vehicle components and improves the exhaust sound. The operating principle of the stronger is based on the absorption and reflection of sound waves. Hot gases leave the combustion chamber at high speed. Once in the stronger, they quickly cool down and slow down. It is more efficient than a catalyst. In addition, the cost of the flame arrester is significantly lower.

The essence of a stronger

Based on the principle of operation, there is much in common between a damper and a resonator. But the task of the first is to dampen sound waves and vibrations from the engine, as well as at the same time reduce the temperature of the exhaust gases.

In simple words, you can describe a stronger like this. This is a device that performs 2 functions simultaneously. Namely, it reduces the temperature, lowering it to a level that is safe for the car and specifically the exhaust system itself, and also reduces the noise level. This automatically refutes some of the myths presented earlier. Thus, you can already draw some of your own conclusions regarding the fairness of blaming the flame arrester for all the troubles associated with the exhaust system of the car.

If we talk about installation, it is carried out on the car muffler pipe, or in the exhaust manifold itself. This allows you to distinguish the main (on the pipe) and collector stronger.

Moreover, according to experts, there is no significant difference in noise level. After replacement, as confirmed by reviews from motorists, the noise of the car even decreases.

Stronger instead of a catalyst. 9 features of this replacement.

Today, markets are inundated with strongers. But, far from it, not every one of them can be installed instead of a catalyst. And all because not all of them have the proper quality.

If you install a stronger (flame arrester) instead of a catalyst, then only one that can actually replace it. Flame arrestors are a kind of deception that convinces the car of the presence of a catalyst. Chinese and similar inventions are not able to display all the functions of a high-quality flame arrester. The most popular are Polish and German made. Among these two options, greater preference is given to Polish products, since they are distinguished by reasonable prices and high quality. The price for Polish stronger is not much higher than for Chinese and other counterfeits, but the quality is identical to branded brands.

Where to order and how to choose a flame arrester?

Buying the first flame arrester you like is wrong. They are selected depending on the car model and personal requests. Accordingly, if the consumer is not familiar with all the properties, then it is better to consult with the manager of the store where you plan to purchase the stronger. Buying “blindly” is a mistake, since an incorrectly selected flame arrester will not bring the benefit that is expected from it. If the car enthusiast knows exactly what he needs, then he should indicate some information when ordering:

Choosing a seller is also an important point. Some stores sell cheap spare parts. Therefore, before purchasing, you need to ask what manufacturers the seller works with.

Interesting topic, I’m also going to cut the cut, I’m thinking about what to put))

guys, it’s better to install a stronger or a Fox type flame arrester, the engine is a turbo V6

In your photo you have the Resonator on the left, and the Stronger on the right. Although they are very similar, they perform completely different functions. The stronger prevents exhaust gases from being sucked back into the cylinder when the piston begins to leave TDC while the valve is still open. The resonator dampens (makes the sound quieter) due to the resonance of sound passing through the holes, they are visible in the photo, but due to the absence of any partitions with minimal loss of speed. They BOTH do NOT impede the movement of hot masses and almost do not cool them down... Therefore, the jar will be ruined =) Flamegas happens, as they say, whoever is good at what, but the main thing is that there are physical obstacles for the gas, against which it cools.

There will be no damage to the jar if it is direct flow)))

Thank you, I read it. I'll bookmark it for the future.
