It is hardly ever relaxing to perceive an injector noise on your Citroen C4 Picasso. It is a noise that happens repeatedly, usually when you accelerate or your engine is idling. However, this symptom may be relating to several kind of complications with your car injectors. It may not be anything major, but when a frequent noise comes out, you have to be sure. Specifically since fixing your Citroen C4 Picasso’s injectors can be costly. That’s why our team chose to compose this article content in order to help 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 C4 Picasso, then at the conceivable reasons from which an injector noise may come.
Benefits of the injectors
Injectors are a very useful component of the operation of your engine motor. They were released to the modern cars 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 possibility, 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 obtained from the various sensors equipping the car (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 C4 Picasso
Listening injector noises on your Citroen C4 Picasso may result from different locations, we will now look into 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 eliminate them. If you perceive another clicking noise but it is not from your injectors, we advise you to read this article content about clicking noise on Citroen C4 Picasso to discover the trigger.
The reasons for injector clicking or knocking noise Citroen C4 Picasso
A clicking or knocking noise from your injectors can be explained for different reasons. In fact, the injectors of your Citroen C4 Picasso have three main tasks, to manage the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to facilitate its combustion. Then, its goal is to manage the air/fuel dosage and finally the homogeneity of the mixture, always with the goal of improving combustion. If one of these three features is altered, 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 Citroen C4 Picasso. The main trigger of these trouble commonly comes 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 comes from another part of the engine of your Citroen C4 Picasso, have a look at this article content for more infos.
The effects of injector noise on Citroen C4 Picasso
Now that we have examined the diverse causes for injector noise on your Citroen C4 Picasso, we will end by stating the possible end result of malfunctioning one or more of your injectors. Whether only one is clogged, or damaged, or your entire fuel rail is involved, you cannot escape these consequences which can quickly 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 effects experienced 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 surely have a loss of power
Finally, you risk deteriorating 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 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>
