What Issues Can Arise from Carbon Deposits in the Engine?
2 Answers
The following issues may arise from carbon deposits in the engine: 1. Reduced engine performance and power output; 2. Increased exhaust emissions; 3. A noticeable lack of power and sluggishness during driving, particularly evident when overtaking, with slower acceleration response, significantly different from when the car was new; 4. Pungent exhaust fumes and emissions exceeding standards. Below are two concepts related to carbon deposits: 1. Engine carbon deposits: A charred substance formed from unsaturated olefins and colloids in fuel under high temperatures during engine operation. 2. Carbon deposits in electrical discharge machining (EDM): Carbon deposits in EDM should be avoided as much as possible, especially in precision mold processing, where they can have a fatal impact.
Engine carbon buildup is really troublesome. I've been driving for over a decade and have seen many similar cases. The most obvious symptom is a noticeable drop in power – the engine responds sluggishly when you step on the gas, making highway overtaking difficult. Fuel consumption also spikes dramatically. My small-displacement car used to consume 7 liters per 100km in the city, but after carbon buildup, it jumped to 9 liters, costing me dozens more in fuel each month. The engine shakes during startup, with unstable idling, especially when the AC is on – the steering wheel vibrates noticeably. If left untreated long-term, carbon deposits can clog fuel injectors or piston rings, accelerating internal engine wear and potentially causing serious failures that cost thousands or even tens of thousands to repair. Prevention is simple: I recommend regular highway driving where high engine RPMs can flush out carbon particles, or using fuel additives for cleaning – it's cost-effective and convenient. Don't wait until the engine warning light comes on; early inspection of spark plugs and valve cleanliness can prevent major issues.
