Know What Happens When a Car’s Exhaust System Stops Working Properly

 

There is a misconception that the car’s efficiency can only be retained by properly maintaining its engine.  While this is true, there are many other components in a car that contribute to its efficiency. And one such overlooked key component of a car is its exhaust system. The exhaust system plays a crucial role in enhancing the efficiency of a car by removing the toxic gases from the vehicle’s engine. 

Consequences of a Faulty Exhaust System 

Let’s take a look at how a car's exhaust system might impact the vehicle’s performance. 

Increases engine strain: The main purpose of a car’s exhaust system is to safely remove toxic gases from the car. To keep a car moving, the engine burns fuel, which produces harmful gases such as carbon monoxide, nitrogen oxides, and hydrocarbons. If these gases are trapped inside the car, it can be extremely dangerous; this is where the exhaust system of a car comes in. If the exhaust system does not work properly and is unable to expel the gases correctly, the engine can experience increased back pressure, leading to higher strain, reduced performance, and increased fuel consumption. 

Emission problems: The catalytic converter in the exhaust system transforms dangerous chemicals like carbon monoxide and nitrogen oxides from the engine into less poisonous gases before releasing them from the car. The environment may suffer if the catalytic converter is unable to filter these gases due to improper operation. A failed MOT may even result from this. Therefore, make sure the car's exhaust is operating correctly to keep the vehicle's emission levels within the permitted range. 

Noise and vibrations: While driving, the car owner may experience noise and vibrations if the exhaust system does not work properly. It happens if the silencer or exhaust pipe is broken.  The main function of the silencer is to reduce noise during combustion. So, if the car is making a lot of noise, it usually indicates that the silencer or exhaust pipe is broken. Due to excessive noise, the trip may turn unpleasant and exhausting. And the vibration frequently happens when the car's exhaust system is loose or misplaced. 

Overheating of the Engine: The engine heats up as the combustion produces gases. However, the engine may overheat and get damaged if the toxic gases produced during the combustion process don’t get released easily. So, it is crucial to have a well-functioning exhaust system to prevent overheating of the engine. 

Signs That Indicate a Car’s Exhaust System Is Malfunctioning 

If any of the below signs are noticed by a car owner/driver, they must take their car to the service centre for exhaust repair Coventry. 

  • Loud or Weird Noises: If the car gets noisy while driving, the exhaust system might be faulty. Loud noises often mean the silencer is damaged. 

  • Strange Smells: While driving, if a weird smell comes out from the car, there might be an exhaust leak. A rotten egg smell could mean the catalytic converter isn't working properly. 

  • Bad Mileage: If a car is consuming more fuel, the exhaust system may not be working well, as a bad exhaust system can make the engine work harder, using more fuel. 

  • Shaking: If the car shakes or the seat/steering wheel vibrates, the exhaust system could be the problem. This often happens when the exhaust pipe is loose. 

The drawback of a faulty exhaust system is not only poor driving performance, but it can also cause the vehicle to fail the MOT test. Passing the MOT test is crucial for vehicles over 3 years old to stay legal. A faulty exhaust system often leads to a failed MOT test. Let’s understand what an MOT test is and why this test is necessary. 

Know What the MOT Test Is 

All vehicles that are older than 3 years old have to pass an MOT test to remain legal on the roads of the UK. Without this certificate, the vehicle cannot be driven on the roads of the UK. The car owner will face a hefty fine of up to 1000 pounds or get penalty points on his/her licence, and even the car insurance may become void if caught driving without a valid MOT certificate. The purpose of this test is to ensure the vehicle complies with all the legal and environmental standards of the UK. When a car passes this test, it means it is safe to drive. During the MOT Coventry test, the professional checks all the important parts of the car, including the exhaust system. For this reason, along with all the parts in the car, the car owners must also ensure the exhaust system of their car is in top shape. 

Conclusion 

One of the most important parts of a car is the exhaust system. The performance of a car can get reduced if its exhaust is not operating correctly. Toxic gases are eliminated from a car by the exhaust system in order to keep the engine running at the right temperature. As a result, it is essential to maintaining the engine's health. Poor performance may result from trapped gases in the car caused by a malfunctioning exhaust system. So, if the car owner encounters hissing, popping, or rumbling sounds coming out from their vehicle while speeding up, they must get their exhaust system checked.
