The exhaust system is a fundamental component of your vehicle that ensures its optimal performance and safety. Its main function is channeling out the harmful combustion gases from the engine to the atmosphere.
Additional Functions of the Exhaust System
The different components of the exhaust assembly work independently or jointly to achieve their specific roles.
- Catalytic converter — converts harmful gases into environmentally friendly gases (e.g. carbon monoxide to carbon dioxide).
- Muffler — reduces noise pollution by suppressing exhaust gas noise.
- Exhaust manifold — collects gasses from the cylinders and directs them to a single channel for easy transport out of the exhaust system.
Each of these parts is essential to the perfect functioning of the exhaust assembly, and a failure of any one part triggers system failure. When this happens, seek the expertise of a professional mechanic to repair the fault.
Indicators of a Faulty Exhaust System
The exhaust releases an unpleasant loud sound with hisses. This happens when it is cracked, and the gas leakage is responsible for the noise.
The smell of raw gasoline in the passenger cabin or at the exhaust is also an indicator of exhaust assembly damage. This is attributed to a faulty component in the exhaust scheme, often caused by a leakage. The gases then invade the car's cabin, hence the smell.
The vehicle experiences reduced acceleration and power output. Exhaust faults affect the performance of the engine thereby reducing its torque. This is notable when driving uphill as the vehicle will seem to struggle with the climb.
A physical effect like a dandling/hanging exhaust pipe due to an impact is also an indicator of an urgent need for repair.
The check engine light is another signal for a fault within the vehicle. Often, any damage to the exhaust system triggers the appearance of this light. It is, therefore, prudent to have it checked by a mechanic and identify the cause.
Reduced fuel efficiency is another key sign of a malfunctioned exhaust assembly. Due to reduced power, the car will consume more fuel to compensate for the efficiency loss. Whenever you notice an upsurge in your vehicle's consumption, please consult a mechanic for diagnosis.
What to Do After Noticing
The first step is to always contact your trusted mechanic or automobile company and schedule a diagnosis and repair session for your car.
Alternatively, if you are familiar with car repairs, troubleshoot and identify the damaged parts and do a temporary fix as you await a trip to the mechanic. This will prevent exacerbation of the damage and maintain the safety of the vehicle.
