Is Fuel Injector Cleaner Useful?

[Patrick]

Fuel injector cleaner does have certain practical effects. However, due to the short duration it remains in the engine for cleaning during use, coupled with the inherent limitations of the no-disassembly cleaning method, its cleaning effectiveness has certain constraints. Here are the relevant details: 1. Definition: A car fuel injector is essentially a simple solenoid valve that generates suction, lifting the needle valve to open the injection port. Fuel is then sprayed at high speed through the annular gap between the needle valve's tip and the injection port, forming a fine mist. The quality of the fuel injector determines the engine's performance. If the injector becomes clogged, it directly affects the vehicle's performance. 2. Cleaning Interval: Generally, if the vehicle is in good condition and the fuel quality is high, cleaning can be performed every 40,000 to 60,000 kilometers. Even if the injector is slightly clogged, there is no need for excessive concern, as impurities can be blown away or dissolved during high-gear acceleration. This is why it is recommended that drivers frequently drive at highway speeds during regular use to reduce the likelihood of carbon deposit formation.
