It is rarely ever pleasant to listen an injector noise on your Alfa Romeo Mito. It is a noise that happens frequently, usually when you accelerate or your engine is idling. However, this warning sign may be related to different types of complications with your car injectors. It may not be anything major, but when a persistent noise comes out, you have to be sure. Especially since fixing your Alfa Romeo Mito’s injectors can be costly. That’s why our team chose to compose this content in order to help you see more clearly, learn about the different conceivable failures and determine your problem. To do this, we will first look at the normal running and usefulness of the injectors in your Alfa Romeo Mito, then at the conceivable causes from which an injector noise may come.
Attributes of the injectors
Injectors are a very significant element of the operation of your engine motor. They were launched to the modern vehicles 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 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 received 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 based on the injectors of your Alfa Romeo Mito
Hearing injector noises on your Alfa Romeo Mito may result from different origins, we will now center on the potential triggers of these. In general, the regular noise of a faulty injector is of the snap type. Here are the different origins of these noises and the solutions to be applied to stop them. If you listen another clicking noise but it is not from your injectors, we recommend you to examine this content about clicking noise on Alfa Romeo Mito to find the reason.
The explanations for injector clicking or knocking noise Alfa Romeo Mito
A clicking or knocking noise from your injectors can be justified by different explanations. Indeed, the injectors of your Alfa Romeo Mito 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 mission 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 attributes 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 due to bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will induce thoses knocking or clicking noises on your Alfa Romeo Mito. The main reason of these problems generally comes from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible blockage will inevitably produce a malfunction of the injector. If after verifying, this noise comes from another component of the engine of your Alfa Romeo Mito, check this content for more infos.
The effects of injector noise on Alfa Romeo Mito
Now that we have analyzed the diverse reasons for injector noise on your Alfa Romeo Mito, 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 repercussions 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 regular consequences noticed by drivers is a noticeable loss of power. Indeed, if your engine is running on 3 out of 4 cylinders for example, you will obviously have a loss of power
Finally, you risk deteriorating 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 suggestions 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>
