It is rarely ever relaxing to listen an injector noise on your Ford Ka. It is a noise that appears repeatedly, usually when you accelerate or your engine is idling. However, this sign may be relating to different kind of trouble with your vehicle injectors. It may not be anything major, but when a repeated noise happens, you have to be sure. Most importantly since replacing your Ford Ka’s injectors can be expensive. That’s why our team decided to prepare this content in order to support you see more clearly, learn about the different possible failures and determine your problem. To do this, we will first look at the normal running and usefulness of the injectors in your Ford Ka, then at the possible causes from which an injector noise may come.
Purposes of the injectors
Injectors are a very useful element of the operation of your engine. They were introduced to the modern automobiles 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 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 collected from the various sensors equipping the vehicle (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 obtain the best possible combustion in the cylinders.
The different triggers of a clicking or knocking noise coming from the injectors of your Ford Ka
Finding out injector noises on your Ford Ka may result from different locations, we will now center on the potential causes of these. In most cases, the typical noise of a faulty injector is of the snap type. Here are the different origins of these noises and the solutions to be adopted to get rid of them. If you listen another clicking noise but it is not from your injectors, we advise you to browse this content about clicking noise on Ford Ka to locate the cause.
The reasons for injector clicking or knocking noise Ford Ka
A clicking or knocking noise from your injectors can be justified by different reasons. In fact, the injectors of your Ford Ka have three main tasks, to manage the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to facilitate its combustion. Then, its objective is to control the air/fuel dosage and at last the homogeneity of the mixture, always with the goal of improving combustion. If one of these three functions is modified, the main functionality 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 induce thoses knocking or clicking noises on your Ford Ka. The main cause of these concerns in most cases originates from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible obstruction 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 Ka, check this content for more informations.
The effects of injector noise on Ford Ka
Now that we have reviewed the several causes for injector noise on your Ford Ka, we will end by stating the possible side effects of malfunctioning one or more of your injectors. Whether only one is blocked, or damaged, or your entire fuel rail is involved, you cannot escape these repercussions which can quickly become considerable….
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 basic consequences noticed by drivers is a severe loss of power. In fact, if your engine is running on 3 out of 4 cylinders for example, you will obviously have a loss of power
Finally, you risk degrading one of your pistons or your engine. Poor combustion will quickly harm your cylinders or pistons and your engine may tighten.
Here are three little recommendations to limit the risks connected 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 changing your diesel fuel filter regularly>
