How to Check the Condition of Fuel Injectors?
1 Answers
To check the condition of fuel injectors, remove them and test using a fuel injector atomization tester to observe their spraying performance. No fuel spray indicates a faulty injector, while poor atomization also suggests a malfunction. For a more professional assessment, the injector can be sent back to the manufacturer for analysis. Here is extended information about automotive fuel injectors: 1. An automotive fuel injector is essentially a simple solenoid valve. When the electromagnetic coil is energized, it generates a magnetic force that lifts the needle valve, opening the injection orifice. Fuel is then sprayed at high speed through the annular gap between the needle valve head and the orifice, forming a fine mist for optimal combustion. 2. As one of the key components in electronic fuel injection engines, the performance of fuel injectors significantly impacts engine operation. Clogged injectors can severely degrade vehicle performance. 3. Clogging typically occurs due to carbon deposits accumulating on the injectors or impurities in the fuel blocking the injector pathways. The primary causes are: First, gasoline naturally contains gums and impurities, or may accumulate dust and contaminants during storage/transportation, gradually forming sludge-like deposits in the fuel tank and fuel lines. Second, unstable components in gasoline can chemically react at certain temperatures, forming sticky gum and resin-like substances.
