What are the main failure types of fuel injectors?
Share
If the engine fuel system lacks maintenance (regular cleaning of the fuel injector), it may cause colloid accumulation inside the fuel injector, but the valve hole is blocked or the needle valve is stuck.
The clogging of the injector valve hole will lead to failure of fuel injection (all clogged) or poor fuel injection atomization (partial clogged), and the sticking of the needle valve will lead to dripping after spraying, resulting in unstable idling speed, poor acceleration or difficult starting of the engine, etc. This phenomenon will seriously affect the emission performance of the engine.
In addition, if the injector connector is leaking water, it will cause a short circuit, resulting in failure to inject fuel, so it needs to be cleaned during maintenance. The engine cannot be started, the engine is running unstable, and the exhaust is severely smoky. These are the symptoms of a broken fuel injector.
The main failure types of injectors:
1. Blockage of the valve hole leads to failure of fuel injection or poor atomization.
2. Needle valve failure leads to flow error or leakage after spraying.
3. The disconnection/short circuit of the connector makes it impossible to inject fuel.
