If the engine gasoline system lacks upkeep (regular cleaning of the fuel injector), it might trigger colloid accumulation inside the gas 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 gasoline injection [https://inatautoparts.com/en-hk/collections/1000cc-injectors lsa injectors] atomization (partial clogged), and the sticking of the needle valve will lead to dripping after spraying, resulting in unstable idling speed, poor acceleration or tough beginning of the engine, etc. This phenomenon will critically affect the emission performance of the engine.

In addition, if the injector connector is leaking water, it's going to trigger a short circuit, resulting in failure to inject gas, so it needs to be cleaned during maintenance. The engine can't be began, the engine is working unstable, and the exhaust is severely smoky. These are the symptoms of a broken fuel injector.

The major failure types of injectors:

1. Blockage of the valve hole results in failure of fuel injection or poor atomization.

2. Needle valve failure results in move error or leakage after spraying.

3. The disconnection/short circuit of the connector makes it impossible to inject fuel.
