How to Reduce Engine Noise in Car Cabin

When you’re driving your car, you probably don’t want to hear the noise of the engine. But even if you’re trying to be as quiet as possible, there’s likely still some noise coming from your engine. In this article, we’ll show you how to reduce engine noise in your car cabin.

What Causes Engine Noise?

There are many sources of engine noise. Here are some of the most common:

– Crankshaft vibration:
This is caused by the motor’s rotating crankshaft. The crankshaft vibrates due to engine RPM and heat. This type of noise is usually noticeable at high speeds and is usually reduced by adding a heavy flywheel to the engine.
– Piston slap:
Piston slap is caused when the piston hits the cylinder head. This creates a loud noise that can be heard through the car’s speakers. To reduce piston slap, use heavier pistons and/or larger valves.
– Piston ring slap:
Piston ring slap occurs when the piston rubs against the top of the piston ring. This can cause a loud noise that can be heard through the car’s speakers. To reduce piston ring slap, use bronze or silicone rings instead of steel rings.
– Camshaft noise:
Camshaft noise is caused by the cam lobes hitting each other as they rotate. This type of noise is usually noticeable at low speeds and is usually reduced by using cam seals that prevent oil from leaking between the cam lobes.
