It is hardly ever enjoyable to notice an injector noise on your Citroen Jumpy. It is a noise that happens repeatedly, usually when you accelerate or your engine is idling. However, this indication may be relating to several kind of concerns with your automobile injectors. It may not be anything major, but when a frequent noise happens, you have to be sure. Especially since fixing your Citroen Jumpy’s injectors can be costly. That’s why our team chose to prepare this article content in order to help you see more clearly, learn about the different plausible failures and determine your trouble. To do this, we will first look at the normal function and usefulness of the injectors in your Citroen Jumpy, then at the plausible reasons from which an injector noise may come.
Purposes of the injectors
Injectors are a very vital component 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 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 accumulated from the various sensors equipping the automobile (engine temperature, acceleration level, engine speed, etc.). Their aim 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 Citroen Jumpy
Discovering injector noises on your Citroen Jumpy may result from different origins, we will now focus on the potential triggers of these. Generally, the usual noise of a faulty injector is of the snap type. Here are the several sources of these noises and the solutions to be used to prevent them. If you notice another clicking noise but it is not from your injectors, we recommend you to examine this article content about clicking noise on Citroen Jumpy to discover the cause.
The explanations for injector clicking or knocking noise Citroen Jumpy
A clicking or knocking noise from your injectors can be justified by different explanations. In fact, the injectors of your Citroen Jumpy have three main missions, to control the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to ease its combustion. Then, its goal is to control the air/fuel dosage and at last the homogeneity of the mixture, always with the target of improving combustion. If one of these three characteristics is modified, 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 because of bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will trigger thoses knocking or clicking noises on your Citroen Jumpy. The main cause of these problems commonly originates from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible blockage will inevitably lead to a malfunction of the injector. If after checking, this noise originates from another element of the engine of your Citroen Jumpy, check this article content for more infos.
The side effects of injector noise on Citroen Jumpy
Now that we have reviewed the several causes for injector noise on your Citroen Jumpy, we will end by stating the possible end result 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 side effects which can fairly quickly become serious….
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 effects noticed by drivers is a distinctive loss of power. In fact, if your engine is running on 3 out of 4 cylinders for example, you will undoubtedly have a loss of power
Finally, you risk degrading one of your pistons or your engine. Poor combustion will fairly quickly harm 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>
