It is hardly ever pleasurable to experience an injector noise on your Ford Kuga. It is a noise that appears repeatedly, usually when you accelerate or your engine is idling. However, this sign may be linked to several sort of complications with your car injectors. It may not be anything major, but when a continuing noise comes out, you have to be sure. Most importantly since replacing your Ford Kuga’s injectors can be costly. That’s why our team decided to create this content page in order to help you see more clearly, learn about the different plausible failures and distinguish your problem. To do this, we will first look at the normal function and usefulness of the injectors in your Ford Kuga, then at the plausible triggers from which an injector noise may come.
Functions of the injectors
Injectors are a very useful element of the operation of your engine. They were launched to the modern cars about 20 years ago. Before their appearance, more conventional carburettor-type intake systems were employed, which handled the intake of air and fuel into the engine cylinders. With the injectors, manufacturers now have the opportunity, thanks to the injectors pump, to control electronically each stage of the intake process very precisely (quantity of fuel injected, air/fuel mixture) via the analysis of the data compiled from the various sensors equipping the car (engine temperature, acceleration level, engine speed, etc.). Their goal 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 causes of a clicking or knocking noise caused by the injectors of your Ford Kuga
Finding out injector noises on your Ford Kuga may come from different sources, we will now focus on the potential causes of these. In most cases, the usual noise of a faulty injector is of the snap type. Here are the different origins of these noises and the solutions to be put into practice to prevent them. If you experience another clicking noise but it is not from your injectors, we advise you to go through this content page about clicking noise on Ford Kuga to discover the reason.
The reasons for injector clicking or knocking noise Ford Kuga
A clicking or knocking noise from your injectors can be explained for different reasons. Indeed, the injectors of your Ford Kuga have three main tasks, to manage the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to ease its combustion. Then, its objective is to control the air/fuel dosage and finally the homogeneity of the mixture, always with the objective of improving combustion. If one of these three tasks is altered, the main functionality of the injectors will be disrupted 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 provoke thoses knocking or clicking noises on your Ford Kuga. The main reason of these concerns in most cases originates from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible obstruction will inevitably result in a malfunction of the injector. If after checking, this noise originates from another element of the engine of your Ford Kuga, check this content page for more infos.
The side effects of injector noise on Ford Kuga
Now that we have examined the diverse reasons for injector noise on your Ford Kuga, we will end by stating the possible effects of malfunctioning one or more of your injectors. Whether only one is blocked, or broken, or your entire fuel rail is involved, you cannot escape these repercussions which can fairly quickly become major….
First, you risk destroying your exhaust system 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 basic effects felt by drivers is a distinctive loss of power. Indeed, if your engine is running on 3 out of 4 cylinders for example, you will surely have a loss of power
Finally, you risk deteriorating one of your pistons or your engine. Poor combustion will fairly quickly affect your cylinders or pistons and your engine may tighten.
Here are three little suggestions to limit the risks relating to 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>
