What does engine cleaning with an IV bag mean?
2 Answers
Automotive IV bag cleaning is a method for cleaning the car engine and related components, targeting areas such as the intake tract, throttle valve, intake valve, fuel injector, and inside the cylinder. During the IV bag cleaning process, a bottle-shaped tool is suspended above the engine. The cleaning agent is poured into this tool and then introduced into the engine through a tube to remove carbon deposits. Functions of automotive IV bag cleaning: The purpose of automotive IV bag cleaning is to remove carbon deposits. After prolonged operation, certain components in gasoline can condense into carbon deposits, which accumulate over time, forming a black, coal-like substance. These deposits adhere to areas such as the intake tract, throttle valve, intake valve, fuel injector, and inside the cylinder, affecting the engine's normal operation. Excessive carbon buildup can lead to various issues, such as difficulty starting the engine, sluggish acceleration, excessive exhaust emissions, increased fuel consumption, fluctuating engine speeds, and poor low-speed acceleration, among others.
Last time I went for car repair, we talked about engine carbon cleaning with the 'hanging bottle' method, which I found quite interesting. Simply put, the shop uses a device shaped like a large hanging bottle, connected to the engine via a tube to pour in special cleaning fluid that removes dirt like carbon deposits or sludge. While the car is running, the fluid mixes with fuel and burns, gradually dissolving those contaminants. The benefits include smoother acceleration, reduced idle vibration, and slightly better fuel efficiency. After doing it once, my car noticeably drove better. But I must remind everyone not to overuse this – only reputable shops are safe, as poor-quality fluid may corrode internal parts. Older cars can do it every 20,000 km, while new cars hardly need it. Spending a few hundred bucks is a reasonable investment, cheaper and faster than engine disassembly, though severely clogged engines still require major overhaul.
