It is never pleasurable to hear an injector noise on your Citroen Cactus. It is a noise that comes up frequently, usually when you accelerate or your engine is idling. However, this warning sign may be related to several types of trouble with your vehicle injectors. It may not be anything serious, but when a recurrent noise comes out, you have to be sure. Especially since repairing your Citroen Cactus’s injectors can be expensive. That’s why our team decided to prepare this article in order to support you see more clearly, learn about the different conceivable failures and identify your trouble. To do this, we will first look at the normal functioning and usefulness of the injectors in your Citroen Cactus, then at the conceivable causes from which an injector noise may come.
Benefits of the injectors
Injectors are a very significant element of the operation of your engine. They were brought in to the modern vehicles about 20 years ago. Before their arrival, 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 opportunity, 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 objective 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 caused by the injectors of your Citroen Cactus
Listening injector noises on your Citroen Cactus may result from different origins, we will now center on the potential causes of these. In most cases, the regular noise of a faulty injector is of the snap type. Here are the several sources of these noises and the solutions to be applied to get rid of them. If you hear another clicking noise but it is not from your injectors, we advise you to examine this article about clicking noise on Citroen Cactus to find the cause.
The explanations for injector clicking or knocking noise Citroen Cactus
A clicking or knocking noise from your injectors can be justified by different explanations. In fact, the injectors of your Citroen Cactus have three main tasks, to control the vaporisation of the fuel, i.e., to transform 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 features is altered, the main role 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 trigger thoses knocking or clicking noises on your Citroen Cactus. The main cause of these situations in most cases originates from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible blockage will inevitably result in a malfunction of the injector. If after checking, this noise originates from another component of the engine of your Citroen Cactus, read this article for more infos.
The consequences of injector noise on Citroen Cactus
Now that we have reviewed the diverse reasons for injector noise on your Citroen Cactus, we will end by stating the possible end result 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 effects which can fairly quickly become critical….
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 common consequences experienced by drivers is a noticeable loss of power. In fact, if your engine is running on 3 out of 4 cylinders for example, you will inevitably have a loss of power
Finally, you risk degrading one of your pistons or your engine. Poor combustion will fairly quickly damage your cylinders or pistons and your engine may tighten.
Here are three little tips 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 changing your diesel fuel filter regularly>
