7 ways to make the car engine quieter
The following are the methods to stop the noise of engine sound :
Use Synthetic Oil and avoid regular Oil
Synthetic oil, due to its good performance, will work efficiently. It will clean the engine well. Lubricate all parts of the engine eventually and reduce the loud noise of the engine.
Remember if you were using any other regular oil and started using synthetic oil, it will take time to settle down the system within a few days. But the result will be satisfactory.
Use of by-pass engine oil filter process
Keep changing the oil every 90 days; using a bypass oil filter will make your dual VVT-I engine quiet.
A bypass filter is called a Pressure Relief Valve.
When the oil consistency becomes thick, the valve opens. If the valves do not open, the filter will burst .It will easily remove the organic and inorganic particles.
Use additives and reduce wear on vital parts.
Using different useful ways, we can increase the engine’s life. Do raise gas mileage, and output will be satisfactory as you expected. An example of an additive is Z Max 55-032..

Exhaust Muffler Gas
Before the gas passes out through the exhaust , it will pass through different paths and resonating chambers due to the Muffler exhaust. This process will help to reduce noise anywhere in the engine.
Exhaust resonator
In the exhaust system, the resonator works to cancel a certain range of sound frequency while you are driving. Resonator r reduces loud noises and sound ranges when exhaust creates regular buzz.
Universal Silencer
It is a volumetric bulb seated at the end of an exhaust. It controls loud noises, the noise that the outflow of combustion gasses makes.

How to stop a car engine from knocking?
Engine knock or pinging happens when a separate pocket of air-fuel mixture ignites after the spark has ignited the air-fuel mixture within the combustion chamber.
Knocking will happen when the peak of the combustion process no longer comes at the optimum moment for the four-stroke cycle. By following a few steps, you can avoid this problem :
Always keep cleaning the combustion chamber

Spark Plugs
The engine’s spark plugs bring an electric spark that ignites the cylinder‘s fuel. These are the reasons for the knocking noises.
Regular car timings checking
