#ArticlePremiere Challenge#Whenever we get into an old car, or our long-loved four-wheeled buddy, do we notice a change in engine sound? Today, we're going to unravel this engine mystery and explain why cars are getting louder and louder as they get longer.
1. Wear parts
Just like we use the muscles and joints of our body, the engine of a car can wear out due to frequent running. Prolonged friction and wear can lead to loosening and failure of internal engine parts, especially critical components such as pistons, crankshafts, and connecting rods. These loose parts cause more vibration and noise when the engine is running.
2. Poor lubrication
Modern car engines rely on lubricating oil to reduce friction and wear. However, with the passage of time and the increase in usage, the lubricant will gradually lose its lubricating properties and become dirty and thin. This will lead to increased friction between the engine parts, which in turn will produce a louder sound. Therefore, changing the oil regularly and maintaining good lubrication is an important step in reducing noise.
3. Exhaust system problems
The sound of a car's engine comes not only from the work of the internal mechanical parts, but also from the exhaust system. Damage or blockage of components such as exhaust pipes, mufflers, and throats can cause exhaust gases to not escape smoothly, resulting in increased noise. At this time, it is particularly important to check and repair the problems in the exhaust system in time.
4. Air filter issues
The engine needs plenty of air and fuel to run. If the air filter is contaminated or clogged, it can cause insufficient air flow, resulting in incomplete combustion and a louder engine. Therefore, ensuring that your air filter is replaced regularly is key to keeping your engine up and running and reducing noise.
5. The hood sound insulation is worn
One factor that has been overlooked is the sound insulation under the hood of the car. Acoustic insulation is often used to reduce the spread of engine noise. However, over time and with daily use, the sound insulation can wear out and fail, making it easier for engine sound to be transmitted to the interior of the vehicle. In this case, remodeling or replacing the acoustic insulation to reduce noise is a solution.
Epilogue:
As an indispensable means of transportation in our lives, it is inevitable that engine noise will gradually increase over time. However, with regular maintenance, timely replacement of key components and attention to the details of use, we can slow down this process and ensure that our car always presents a comfortable and pleasant driving experience. Let's cherish every roar of the engine and start the journey of our dreams!
