What Are the Effects of Excessive Engine Carbon Deposits?

[LaMariana]

Here are the specific effects caused by excessive engine carbon deposits: 1. Vehicle idle vibration: Excessive carbon deposits often adhere to the intake valve, reducing the pressure in the engine cylinders, which causes the vehicle to vibrate at idle. The interruption of the air-fuel mixture entering the combustion chamber reduces engine efficiency. 2. Failure to start: Excessive carbon deposits can cause issues with components like the spark plugs, affecting the quality of ignition and even leading to failure to start. 3. Excessive engine exhaust emissions: Carbon deposits usually form due to incomplete combustion of gasoline. When carbon deposits adhere to the oxygen sensor, it cannot accurately detect exhaust conditions, often leading to excessive engine emissions and the release of more toxic gases like PM2.5.
