Why don't old cars recommend cleaning up carbon deposits? Does it matter if the car has not been washed for ten years?

Old cars need to be cleaned of carbon deposits. The parts of the old car have worn out, the fuel consumption will increase and the power will decrease. If the carbon deposit is not cleaned up, there will be phenomena such as weak acceleration, unstable idle speed and difficult start-up when the carbon deposit is serious.

If there is more carbon deposit, the intake passage will be blocked, and it will be difficult for the air for auxiliary combustion to enter the cylinder, so the ignition time of the cylinder will be delayed due to the increase of pressure, the power of the vehicle engine will be reduced, and the acceleration will be weakened. When fuel is injected, some fuel will be adsorbed by carbon deposits, and insufficient fuel supply will affect the start of the vehicle. The engine will also be unable to send gasoline and air from the combustion chamber to the combustion chamber because of carbon deposition, which will affect the speed and make the engine idling unstable.

Does it matter if the car has not been washed for ten years?

The influence of carbon deposition on vehicles that have not been washed for ten years is very great. Generally speaking, the cycle for vehicles to clean up carbon deposits is one to twenty thousand kilometers. The bad driving habits of the owner, the quality of fuel and the temperature of the engine will all affect the carbon deposition of the engine. If the engine has serious carbon deposit, it is necessary to clean up the carbon deposit in advance. If the engine carbon deposit is slight, the cycle of removing carbon deposit can be postponed.

The best way to clean the carbon deposit is to remove the throttle and then clean the front and rear of the throttle with carburetor cleaner. It is best to dry it with cotton cloth to clean it. Removing carbon deposits from diesel vehicles. Before replacing the new engine oil, pour the cleaner into the oil tank, mix it with the engine oil, and then run at idle speed for more than 10 minutes, and the carbon deposits in the engine will be gradually cleaned up. Car owners can buy cleaning agent for the air intake system to clean the carbon deposits in the air intake and manifold, pour the cleaning agent into the liquid storage tank of the cleaning equipment, and then connect it with the air intake system. After starting the vehicle, the cleaning agent can be sucked into the air intake by vacuum to clean the carbon deposit.
