How Do Car Exhausts Breathe Flame?

These flames that suddenly come out of car exhaust are also known as after fire, and of course every car It is not suitable to repel this fire. Again, let us say from the beginning that this situation is not as simple as you think.

Well, from car exhausts What kind of system is behind the fire eruption?

In fact, the basis of these flames is the mixture of fuel and oxygen vaporized in an engine suitable for ignition.

These explosions, which can be kept under control, cause the engine and wheels to rotate. But sometimes, not all of this fuel is burned. If fuel If it manages to enter the hot exhaust pipes and meet the oxygen outside, That’s when it ignites with a huge fire when it comes out of the exhaust pipe.

Of course, this does not happen in a typical car used in daily life. of these vehicles Because their engines are smallerthe amount of fuel it needs to run is much less.

In addition, passenger vehicles have a comprehensive exhaust system that allows fuel to pass through before reaching the exhaust pipe.

catalytic converter

Again in the exhausts of these vehicles catalytic converters It is also available. These converters aim to provide cleaner emissions and remove pollutants such as excessive amounts of fuel vapor.

However, if it is a Lamborghini with a 12-cylinder engine and considering that this vehicle emits 760 horsepower worth of combustion gas, it needs a very hot exhaust results. In short, it is not possible for the catalytic converter to be active without catching fire thanks to the extra fuel.

It is also possible to see these flame explosions in engines with slightly smaller turbochargers and especially engines with anti-lag systems.

Anti-lag

Turbochargers provide extra power by sucking compressed air into the engine. This is thanks to the anti-lag found in racing and tuner cars. The basis of operation of this part is to suck compressed air into the engine.

We all know that fire cannot exist without oxygen. This results in better combustion and a more powerful engine. Turbochargers, on the other hand, are powered by car exhaust gases, which It winds a turbine connected to a propeller that begins to draw in air.

The moment you take your foot off the gas, exhaust gases and turbochargers stop. When you put your foot on the gas again, the extra time it takes for the turbo to switch back to boost mode is known as delay.

Anti-delay in vehicles allows the engine to be programmed to create a smaller ignition with a delay.

A late spark not only allows more fuel to enter the cylinders, but also causes combustion to slow down. to occur as late as possible It also causes. This fuel mixture continues to ignite outside the cylinder.

In addition, the heat of the exhaust causes the turbine to wind, and thus the vehicle’s engine receives power continuously. Like this Flames resulting from combustion outside the engine come out of the exhaust pipe.

Another thing that causes exhaust flares is two-stage rev limiters, or launch control systems.

Rev limiters are located near the engine’s redline and allow an internal combustion engine to It is the maximum engine speed designed to ensure operation without damaging internal parts.

Essentially, vehicles are programmed to limit the engine’s rotation speed to maximize acceleration while preventing the engine from blowing up. It’s almost as if these limiters control the engine for take-off. He tells him to stay in the period he thinks is best.

This allows the tires to provide as much grip as possible, to minimize wheel skidding and allows the vehicle to accelerate on the road while starting up again after stopping.

Besides all this have a cool fire breathing car If you do, you may want to think twice. Because the use of vehicles modified to produce flames in public places can often result in various penalties.
