What is the Function of Engine Cleaner?

Engine internal cleaner is a product developed to address the issue of deposits. More details are as follows: 1. It is composed of multiple highly effective cleaning components and is an additive capable of automatically cleaning the internal lubrication system. 2. By adding the engine internal cleaner into the engine crankcase, the cleaning process is completed as the engine oil flows during operation. This dissolves gum, loosens bonded deposits, and causes them to detach. Deposits such as varnish, carbon buildup, and sludge on piston rings, piston skirts, etc., will be thoroughly removed. The dislodged deposits are then filtered out by the oil filter through the oil circulation or settle in the oil pan, to be removed when replacing or cleaning the oil filter and oil pan. 3. Engine internal cleaner mainly consists of surfactants, alkali, chelating agents, detergents, metal corrosion inhibitors, water, etc. The products on the market are primarily divided into three categories: sludge removers, carbon deposit removers, and sludge-carbon deposit removers.

I've been driving an old car for over a decade. Engine cleaners work by removing carbon deposits and sludge inside the engine, making the car run smoother. After prolonged use, carbon buildup acts like accumulated grime, causing sluggish acceleration, increased vibration, and higher fuel consumption. When added to the engine oil during operation, the cleaner dissolves and flushes away these contaminants. The benefits are numerous: restoring engine performance, reducing wear, lowering noise levels, and improving throttle response. Frequent city traffic congestion or short-distance driving tends to accelerate deposit formation. Regular use of cleaners during oil changes, approximately every 20,000 kilometers, helps maintain engine vitality, extend its lifespan, and save on maintenance costs. When selecting products, pay attention to whether the ingredients are gentle yet effective—avoid low-quality products that could damage the engine.

For car enthusiasts who love to delve into details, engine cleaners primarily remove carbon deposits from pistons and combustion chambers, preventing them from clogging valves and affecting ignition compression. Carbon buildup, formed from gasoline residues, hinders combustion efficiency and increases emissions. The cleaner dissolves deposits through chemical action, improving air-fuel mixture and enhancing efficiency. After use, you may feel quicker acceleration, smoother idling, and slightly reduced emissions. It also protects key components like piston rings, reducing wear. When choosing a cleaner, distinguish between solvent-based and detergent-based types. It's recommended to use them during maintenance, combined with replacing the filter to ensure thorough flushing and avoid residue. In the long run, it helps maintain engine condition and economically prevents major overhauls.

In terms of safe driving, I believe the key benefit of fuel system cleaner is reducing failure risks. It removes carbon deposits to minimize knocking and stalling hazards, ensuring reliable engine operation with stable starts in both winter and summer. After using the cleaner, the car feels smoother, preventing unexpected breakdowns and boosting driving confidence. When combined with regular maintenance, it also delays oil degradation, protects the lubrication system, and extends overall engine lifespan. It's worth using periodically to maintain safe travels.
