Is Fuel Injector Cleaning Necessary?
2 Answers
Fuel injector cleaning is very necessary. Here are the detailed explanations: 1. If the fuel injector is clogged or has excessive carbon deposits, it needs to be cleaned promptly. 2. The cleaning interval for fuel injectors is every 2 years or 50,000 kilometers. 3. If the vehicle frequently drives on roads with poor conditions, the fuel injector should be cleaned earlier (areas with poor fuel quality also require earlier cleaning). 4. If the fuel injector becomes clogged, the vehicle's power will be significantly affected, and in severe cases, it may even fail to ignite. 5. The main function of a car's fuel injector is to coordinate the ignition timing of the valve train and inject gasoline into the cylinder in a timely and measured manner, allowing the vehicle to generate power after the spark plug ignites. 6. The condition of the fuel injector affects the degree of fuel atomization; the higher the atomization degree, the higher the vehicle's combustion efficiency.
I've been running an auto repair shop for over a decade. Whether to clean fuel injectors depends on the situation. Vehicles under 50,000-60,000 km generally don't need it, but older cars frequently stuck in traffic or using gas from small stations tend to accumulate carbon deposits. Last time we had a Bora with poor acceleration - after cleaning the injectors, its fuel consumption dropped by 0.8L immediately. Watch for these symptoms: violent shaking during cold starts, sluggish response during sudden acceleration, or gasoline smell from exhaust - these mean it's time for cleaning. With modern equipment, we can do ultrasonic cleaning without engine disassembly for just around 100 yuan. Neglecting this may eventually require replacing entire injectors, which could cost thousands - much more expensive.
