How to Soundproof Excessive Engine Noise?

[Martinez]

Here are the methods for soundproofing excessive engine noise: 1. If the engine noise is very loud and you want to soundproof it, you can install soundproofing cotton on the engine cover, which can effectively block a portion of the noise. You can also install soundproofing cotton inside the car doors to block some of the noise as well; 2. There are many reasons that can cause excessive engine noise, and some cars' engines are noisier by design when they leave the factory; 3. Most noisy engines are direct-injection engines. Many direct-injection engines make a ticking sound during operation, which is actually normal—it's the sound of the high-pressure fuel pump working.
