How to Solve Engine Noise?

[DeJoshua]

Methods to solve engine noise are as follows: 1. If the engine noise is loud and you want to reduce it, you can install soundproofing cotton on the engine cover, which can effectively block part of the noise. You can also install soundproofing cotton inside the car doors to block some noise. 2. There are many reasons for loud engine noise, and some cars have inherently noisy engines from the factory. 3. Most noisy engines are direct-injection engines, and many direct-injection engines produce a ticking sound during operation. This is actually normal and is the sound of the high-pressure fuel pump working.
