4 Pcs Fuel Injectors
What Are Fuel Injectors?
Fuel injectors spray fuel into a car’s engine using electronic controlled valves, capable of opening and closing many times a second. They have an atomising nozzle that distributes the petrol or diesel evenly, for optimum combustion and efficiency. Injectors were introduced as a replacement for the old carburettor system, since they help engines run with greater fuel efficiency and also help to reduce emissions.
A car generally has one fuel injector per cylinder. So, if you drive a four-cylinder car, it will most likely have four fuel injectors.
How Do Fuel Injectors Work?
Fuel injectors control the volume of fuel delivered to the combustion chamber, ensuring the right amount is injected at the right time. The process is:
The fuel pump pushes petrol or diesel through the fuel lines to the injectors.
The ECU (engine control unit) uses sensors to work out the right time to fire the injectors and spray fuel into the combustion chamber.
When the ECU activates the injector, pressurised fuel is sprayed into the combustion chamber through the nozzles. Because the nozzles are so small, the fuel is atomised, which makes it burn more efficiently.
Common Bad Fuel Injector Symptoms
1.Rough Idle or Engine Stalls
Because your vehicle is not getting enough fuel or an uneven supply of fuel, the RPM while idling drops below the optimal level and results in a rough or even violent idle. If the RPM falls too low, the car will actually stall and you will need to restart.
2. Engine Vibrates
A faulty fuel injector will cause the corresponding cylinder to not be able to fire. This means that while driving, the engine will vibrate or hiccup after it tries to finish each cycle without fuel.
3.Engine Misfires
If the engine does not get enough fuel sprayed into due to a clogged injector, then the engine will misfire as you drive. Your vehicle will struggle to accelerate or there will be a pause after you step on the gas pedal.
4.Check Engine Light Turns On
The most obvious sign of a problem is when the “Check Engine” light illuminates on your dashboard. Although this could mean a lot of things, a bad fuel injector could be one of them.
5.Fuel Leak
If your fuel injector is actually broken or cracked from damage or old age, then gasoline will begin to leak out of it. This means the fuel won’t be able to reach the nozzle but instead, it will leak from the body.
6.Fuel Odor
This goes along with a fuel leak but when you have gasoline that’s not getting burned due to a damaged injector or one that’s stuck open, you’re going to smell gasoline. Sometimes the issue may be your fuel lines or a faulty sensor telling the ECU to inject more fuel than in necessary.
7.Engine Surge
If the fuel injector is spraying too much fuel into the engine cylinder, this will create a surge in the engine causing your acceleration to be much slower. When you drive, you’ll notice that the engine RPM will change noticeable under constant load rather than remaining at a constant RPM.
8.Bad Fuel Economy
If the engine is not getting the right amount of fuel it needs for combustion, then it will place more demand on the injector to supply it with additional fuel. This results in poor fuel economy due to the excess fuel that the car’s ECU thinks is needed but is in fact not necessary.
9.Failed Emissions Test
How Often Do Fuel Injectors Need to Be Replaced?
Fuel injectors tend to be very reliable. On average, they last between 80,000 and 100,000 miles. With proper maintenance and a close eye, you can probably get yours to last toward the higher end of that spectrum. If your vehicle is nearing that mileage since it was built or since you had replacement injectors installed, it could be time to have them replaced. You definitely want them looked at if they are getting that far along.
