*How the fuel injector works and symptoms of its damage* *How the fuel injector works:* The fuel injector sprays gasoline directly into the combustion chamber inside the engine (cylinder). The timing and amount of spray are controlled by the engine control unit (ECU), which takes readings from multiple sensors to precisely adjust the combustion process. Through this process, the fuel is mixed with air to produce engine power. *Symptoms of injector damage:* 1. *Check Engine light comes on:* If this light appears, there may be a malfunction in the fuel injection system, although the causes of the light are multiple. 2. *Engine vibration or tremor during operation:* Lack of fuel in the combustion chamber due to clogged injectors may lead to noticeable vibrations while driving. 3. *Poor vehicle performance:* Injector damage weakens the combustion process, leading to a significant loss of the power needed to accelerate the car. 4. *Fuel leak or gasoline smell:* Cracked or damaged injectors can cause gasoline to leak, which can be noticed by the smell of gasoline or by seeing the leak around the engine area. 5. *Increased gasoline consumption:* Damaged injectors sometimes cause them to not close completely, which increases the amount of fuel entering the engine. 6. *Irregular engine rotation:* The driver may notice a cut in the engine's performance or it may stop working suddenly. 7. *Black smoke coming out of the muffler:* Excess gasoline entering the combustion chamber due to damaged injectors leads to incomplete combustion, resulting in black smoke. 8. *Loud engine noise:* Damaged injectors may make the engine sound louder than usual due to a disruption in the combustion process. 9. *Delay in starting:* Not enough fuel reaching the combustion chamber prevents the engine from starting at the appropriate time. *Note:* Some of these symptoms are similar to other problems in the car, so it is best to have the car checked by a specialist to confirm the cause of the malfunction
