It is rarely ever pleasant to experience an injector noise on your Ford Flex. It is a noise that appears continually, usually when you accelerate or your engine is idling. However, this symptom may be related to several kind of problems with your automobile injectors. It may not be anything major, but when a continuing noise appears, you have to be sure. Especially since replacing your Ford Flex’s injectors can be costly. That’s why our team decided to produce this article in order to help you see more clearly, learn about the different plausible failures and distinguish your issue. To do this, we will first look at the normal functioning and usefulness of the injectors in your Ford Flex, then at the plausible triggers from which an injector noise may come.
Attributes of the injectors
Injectors are a very significant element of the operation of your engine. They were introduced to the modern vehicles about 20 years ago. Before their introduction, more conventional carburettor-type intake systems were used, which handled the intake of air and fuel into the engine cylinders. With the injectors, manufacturers now have the ability, thanks to the injectors pump, to control electronically each stage of the intake process very accurately (quantity of fuel injected, air/fuel mixture) via the analysis of the data received from the various sensors equipping the automobile (engine temperature, acceleration level, engine speed, etc.). Their purpose is therefore to inject under high pressure a precise quantity of an air/fuel mixture at a perfect timing to get the best possible combustion in the cylinders.
The different reasons of a clicking or knocking noise coming from the injectors of your Ford Flex
Finding out injector noises on your Ford Flex may result from different origins, we will now focus on the potential causes of these. In most cases, the typical noise of a faulty injector is of the snap type. Here are the several sources of these noises and the solutions to be adopted to get rid of them. If you experience another clicking noise but it is not from your injectors, we recommend you to go through this article about clicking noise on Ford Flex to locate the cause.
The reasons for injector clicking or knocking noise Ford Flex
A clicking or knocking noise from your injectors can be justified by different reasons. Indeed, the injectors of your Ford Flex have three main missions, to control the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to ease its combustion. Then, its objective is to deal with the air/fuel dosage and at last the homogeneity of the mixture, always with the aim of improving combustion. If one of these three functions is modified, the main purpose of the injectors will be disturbed and this will lead to poor combustion. This bad combustion will be a violent explosion in the cylinders resulting from bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will trigger thoses knocking or clicking noises on your Ford Flex. The main cause of these concerns generally originates from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible blockage will inevitably end up in a malfunction of the injector. If after verifying, this noise originates from another element of the engine of your Ford Flex, browse this article for more infos.
The end result of injector noise on Ford Flex
Now that we have analyzed the different causes for injector noise on your Ford Flex, we will end by stating the possible side effects of malfunctioning one or more of your injectors. Whether only one is obstructed, or damaged, or your entire fuel rail is involved, you cannot escape these side effects which can promptly become severe….
First, you risk destroying your exhaust unit in the long run, because the unburned fuel residues that will end up in your exhaust system can corrode the metal in it.
One of the most known consequences noticed by drivers is a significant loss of power. Indeed, if your engine is running on 3 out of 4 cylinders for example, you will inevitably have a loss of power
Finally, you risk deteriorating one of your pistons or your engine. Poor combustion will promptly affect your cylinders or pistons and your engine may tighten.
Here are three little recommendations to limit the risks associated with your injectors and protect you from engine failure:
- Do not drive at the bottom of the tank, as you may absorb impurities
- Use quality fuel
- Think of swapping your diesel fuel filter regularly>
