What is the reason why the sound of sagitar engine becomes louder?

If there is carbon deposit, just clean the throttle.

Because the old engine oil is getting thinner and thinner, more and more carbon is deposited. When the engine oil is thin, it is easy to run the engine oil, resulting in more and more carbon deposits and loss of a lot of power. When replacing the new oil, the engine can't adapt to the viscosity of the oil, which may increase the speed and cause engine noise.

Coolant problem: if the temperature is too low, it is likely to cause problems and the noise of the engine will become louder. This should be checked and replaced to avoid other problems.

Precautions:

When a high-quality engine is used, the metal surfaces inside the cylinder block run at high speed and rub against each other at a high temperature of hundreds of degrees Celsius, which will inevitably bring about engine wear. Especially for trucks that run continuously for a long time and have heavy loads, the possibility of wear and tear is greater.

High-quality engine oil can effectively control engine wear, not only that, but also effectively inhibit the generation of carbon deposits and sludge, thus controlling the wear of impurities in the oil circuit on the engine surface.
