Carbon Accumulation: Symptoms And Solutions

Engine carbon accumulation is a common problem in the long-term use of fuel vehicles, caused by carbon particles generated by incomplete combustion of fuel adhering to key internal components of the engine, which can seriously affect engine performance and service life. Timely identification of carbon accumulation symptoms and adoption of effective solutions are crucial for ensuring the normal operation of vehicles.

1、 Common Symptoms of Carbon Accumulation

The symptoms of carbon accumulation are often reflected in the engine operating status and vehicle driving experience. Firstly, it is difficult to start, especially when starting a cold car. The engine needs multiple attempts to start, and after starting, it may also be accompanied by unstable idle and body shaking. This is because carbon particles adhere to the throttle valve and fuel injectors, affecting fuel atomization and intake volume. Secondly, there is a significant decrease in power, with weak acceleration and difficulty climbing hills. Even if the accelerator is pressed deeply, the power response is relatively slow. This is due to carbon deposits in the combustion chamber, which reduces combustion efficiency and prevents the full release of power. In addition, an increase in fuel consumption is also a typical symptom, as carbon deposits cause an imbalance in the engine's air-fuel ratio, requiring more fuel consumption to maintain normal power; Some vehicles may also experience excessive exhaust emissions, with carbon particles being emitted along with the exhaust, resulting in blackening of the exhaust color and worsening of the odor.

2、 Solution to Carbon Accumulation

Different solutions can be adopted based on the severity of carbon accumulation. Mild carbon buildup can be improved through daily driving optimization, such as regular high-speed driving, using high RPM to raise exhaust temperature, and burning off some attached carbon particles; Simultaneously choose high-quality fuel to reduce the probability of incomplete combustion of fuel. Moderate carbon buildup can be treated with professional fuel additives, whose active ingredients can dissolve carbon buildup and be discharged with exhaust gas. It is easy to operate, cost-effective, and suitable for regular maintenance and use. Severe carbon deposition requires disassembly and cleaning, such as disassembling throttle valves, fuel injectors, intake manifolds, and other components for manual wiping or ultrasonic cleaning. This method of cleaning thoroughly takes a long time and is expensive. It is recommended to go to a professional repair shop after driving the vehicle for a certain mileage (usually 30000 to 50000 kilometers). In addition, regularly replacing the air filter and maintaining the normal operating temperature of the engine can effectively prevent the accumulation of carbon.
