How to Check the Condition of Fuel Injectors?
1 Answers
To inspect the condition of fuel injectors, they need to be removed and tested using a fuel injector atomization tester to observe their spray pattern. If no fuel is sprayed, the injector is definitely damaged; if the fuel atomization is noticeably poor, it also indicates damage. For more professional analysis, the injector should be sent back to the manufacturer. Below is an introduction to automotive fuel injectors: A car fuel injector is essentially a simple solenoid valve. When the electromagnetic coil is energized, it creates magnetic force that lifts the needle valve, opening the injection hole. Fuel is then sprayed at high speed through the annular gap between the needle valve tip and the injection hole, forming a fine mist for optimal combustion. As one of the key components in electronic fuel injection engines, the performance of fuel injectors significantly impacts engine operation.
