Is It Necessary to Clean Carbon Deposits Inside the Engine Cylinder?
2 Answers
Cleaning carbon deposits inside the engine cylinder is necessary. Carbon deposits are inevitable in every vehicle, though the amount varies. Excessive carbon buildup can alter the engine's original structural parameters, reduce engine power, and increase fuel consumption. In severe cases, it may also cause engine knocking, abnormal acceleration noises, and damage to pistons and crankshafts. Additional tips for winter maintenance: 1. Keep the engine warm: The main reason for difficult cold starts is the low temperature of the engine. Therefore, keeping the engine warm and preventing cold wind from directly blowing into the engine compartment can help avoid starting issues. 2. Pay attention to the direction of the car's front: When parking in winter, it's best to face the car's front toward a building to use the structure as a windbreak, preventing the engine from becoming too cold due to the cold wind.
I've been driving for over a decade and never take maintenance lightly. Carbon buildup in cylinders is extremely common, especially in today's direct injection engines which are particularly prone to carbon deposits. Last week I helped my neighbor clean his 80,000-kilometer car - when we opened up the engine, the back of the valves were completely black. If left uncleaned for long periods, you'll notice the car's acceleration becomes sluggish, the steering wheel vibrates like a massage chair at red lights, and the exhaust develops a pungent smell. Most importantly, fuel consumption secretly creeps up! Veteran driver's advice: For turbocharged cars doing mostly short city trips, cleaning every 30-40 thousand kilometers is safest. Disassembly cleaning works far better than fuel system cleaners.
