The issue of carbon deposition in automobiles has always been the focus of attention of car owners. Carbon deposits not only affect vehicle performance, but can also lead to higher fuel consumption. So, how can you tell if there is carbon deposition in a car? Here are a few practical ways to tell.

First of all, it is an intuitive way to observe the changes in fuel consumption. Under normal driving conditions, if the vehicle's fuel consumption suddenly increases, and external factors such as driving habits and road conditions do not change, it is likely to be a signal of carbon deposition inside the engine. Carbon deposits affect the combustion efficiency of the engine, preventing fuel from being fully combusted, requiring more fuel to maintain the same power output. For example, a tank of fuel that used to be able to travel 400 kilometers can now only run about 0 kilometers, which may be an abnormal fuel consumption caused by carbon deposits.

Secondly, the dynamic performance of the vehicle is also an important basis for judging carbon deposits. When there is carbon deposits inside the engine, it will interfere with the normal ratio of the mixture and the combustion process, thereby reducing the power output of the engine. During driving, if the owner obviously feels that the vehicle is slow to accelerate, especially when overtaking, climbing and other power output is needed, it is likely that the combustion chamber, air intake and other key parts have generated carbon deposits.

Engine idling is also a key indicator of carbon deposits. Under normal circumstances, the engine idle speed should be smooth. If the owner finds that the engine shake is significantly aggravated when idling, or the idle speed is unstable and the tachometer index swings up and down, then it is possible that carbon deposits have been generated in the throttle and other parts. Carbon deposits can affect the angle at which the throttle opens and closes, resulting in unstable air intake, which in turn causes engine idle jitter.

By observing changes in fuel consumption, checking power performance, and paying attention to engine idling, car owners can initially determine whether the car has carbon deposits. Once signs of carbon deposition are found, measures should be taken to clean it up in time to ensure the normal operation of the vehicle and prolong the service life.
