When you take your car for a routine check-up, you will see that many mechanics attribute the problems to a faulty fuel injector. In fact, the most competent car mechanic Adelaide has to offer will tell you how important it is to keep an eye out for faulty injectors. In this article, you’ll learn all about comprehensive fuel injector repair.
History of the Fuel Injector
The concept of a fuel injector is quite old, but it was not applied to mainstream cars until a few years ago. In the old days, fuel injectors were generally limited to racing cars and “hot rods”. In the 21st century, fuel injectors have become an essential element of the modern vehicle’s fuel management system.
What Exactly Is a Fuel Injector?
A fuel injector is a device that is in charge of injecting fuel into the engine of the car. The device is fit with a number of valves that can be controlled electronically. These valves open and close multiple times in a second to make sure that the engine receives its required fuel amount.
It is the duty of the fuel injector to ensure that the engine always receives an optimum ratio of air and fuel. For the best combustion and fuel efficiency, a constant ratio of fuel and air has to be maintained. Old car models had a carburettor system – but in newer vehicles, the fuel injectors make the system way more efficient.
How Exactly Does a Fuel Injector Work?
As said before, the duty of a fuel injector is to control the volume of fuel received by the engine. First of all, the fuel pump of the car pushes the fuel towards the injector. Every car is fit with a device called an Electronic Control Unit or ECU. The ECU is an on-board computer that determines the way the fuel injector works. The fuel injector follows the direction of the ECU unit and sprays pressurized fuel into the engine. By obeying the exact commands of the ECU unit, the fuel injector is able to maintain a constant ratio of fuel and air.
Signs and Symptoms That You Might Need a Fuel Injector Specialist
Here are some of the signs and symptoms that will warn you beforehand if you need to visit an auto repair shop and ask for a fuel injector specialist.
1. Difficulty Starting the Car: One scenario where you might need a fuel injector cleaning service or a repair service is if your car has difficulty starting. A leaky fuel injector can cause the fuel pressure to fall, which means that the engine does not receive proper fuel. If you can smell gas coming from the engine bay of your car when it doesn’t start, that’s probably a bad fuel injector.
2. Engine Keeps Stalling: If your car’s engine keeps stalling all of the time without a reason, then that is a sign of a faulty fuel injector. You might need to go for fuel injector repair since the device is not supplying the engine with the amount of fuel it needs. The nozzles on your injector might be badly blocked.
3. Bad Fuel Economy: If you notice that the mileage of your car has gone down suddenly in the past few days, then it is a good time to consider fuel injector replacement. A bad fuel injector means that your car is unable to utilize the fuel properly. As a result, your car’s control unit will try to make up for it by providing the unit with extra fuel. All of this will eventually result in the loss of fuel.
4. Failing Emissions Test: If your car has recently failed its Emissions Test, then you should go to the auto repair shop ASAP. A bad fuel injector that has blocked nozzles will not be able to provide the engine with the optimum mix of air and fuel. The ensuing improper combustion will send harmful emissions to the vehicle’s exhaust system.
5. Vibrating or Misfiring Engine: If your car has a faulty fuel injector, then your engine will be prone to misfiring and vibrating. A vibrating engine is not in itself a sign of a bad fuel injector. However, if you notice poor fuel economy and a smell of gasoline along with a vibrating engine, then you will need to consider getting your fuel injector serviced.
Last but not least, one of the biggest signs of a faulty fuel injector that needs to be subjected to an injector cleaning service is the “check engine” light. Try to get it repaired quickly.
Final Thoughts
If you are experiencing any of the above 5 issues, then you should take your car to the best car mechanic Adelaide has to offer. It is very important to get scheduled and regular maintenance done on the fuel injector if you want to enjoy proper uninterrupted service.
