3 signals that indicate serious carbon deposits in your engine

Carbon deposits on vehicles bother many drivers because they cause many problems. Carbon deposits are inevitable no matter how you use the truck. Carbon deposits need to be cleaned in time. So how do you know if your vehicle has carbon deposits? There are several signals.

1. Power changes

Under normal circumstances, the engine's power output should be stable, but if there is too much carbon deposit inside the engine, it will affect the normal combustion of fuel and the intake volume, resulting in reduced combustion efficiency and incomplete combustion, and you will feel that your vehicle's power output is insufficient. For example, when you are overtaking, the power will come up immediately after you step on the accelerator, but now it has become slow, and it takes a while to get strong power after stepping on the accelerator, or even the power has decreased and it has become powerless.

In addition, when the power drops, the fuel consumption will definitely increase, because the combustion is incomplete and some fuel is wasted. If other factors such as insufficient tire pressure and changes in road conditions are excluded, then the sudden increase in fuel consumption is likely a manifestation of excessive carbon deposits in the engine.

2. Severe engine shaking at idle speed

Shaking at idle speed is the most obvious sign of carbon deposits. Normal vehicles should be stable at idle speed. In severe cases, the engine shaking can be felt in the cab, and the steering wheel will also shake. You can clearly feel it when holding the steering wheel. This is most likely caused by carbon deposits. Originally, at idle speed, the intake and fuel injection volumes are the smallest, which can only keep the engine from stalling. If carbon deposits form, the air intake and fuel injection volumes will further decrease. At this point, the engine can only barely maintain operation and will shake due to lack of power.

3. Observe the throttle and exhaust pipe

This is the most intuitive. Check whether the area around the throttle baffle has turned black and whether the area is large. If it is a thin strip and the blackness is not serious, it means that the carbon deposit is very slight. If the black circle is very thick and even looks oily, it means that the carbon deposit is serious. As long as the throttle is seriously carbon deposited, there is a high probability that there will be a lot of carbon deposits in other places.

The second place to look is the exhaust pipe. Wipe the inside of the exhaust pipe with your hands or a paper towel. If it is very black, it also means that there is a lot of carbon deposits in the cylinder. Because the exhaust gas is discharged from the exhaust pipe, there are a lot of carbon deposits in the exhaust gas, which are gathered at the exhaust pipe outlet, indicating that the combustion is not complete.
