It is hardly ever pleasurable to listen to an injector noise on your Mitsubishi Mirage. It is a noise that comes up continually, usually when you accelerate or your engine is idling. However, this sign may be connected to multiple types of complications with your automobile injectors. It may not be anything severe, but when a repeated noise appears, you have to be sure. Most importantly since fixing your Mitsubishi Mirage’s injectors can be expensive. That’s why our team chose to compose this content in order to help you see more clearly, learn about the different possible failures and distinguish your trouble. To do this, we will first look at the normal running and usefulness of the injectors in your Mitsubishi Mirage, then at the possible causes from which an injector noise may come.injector-noise-mitsubishi-mirage

Attributes of the injectors

Injectors are a very important element of the operation of your engine. They were launched to the modern cars about 20 years ago. Before their arrival, 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 received from the various sensors equipping the automobile (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 causes of a clicking or knocking noise caused by the injectors of your Mitsubishi Mirage

Listening injector noises on your Mitsubishi Mirage may originate from different sources, we will now look into the potential causes of these. In general, the common noise of a faulty injector is of the snap type. Here are the different sources of these noises and the solutions to be implemented to prevent them. If you listen to another clicking noise but it is not from your injectors, we recommend you to examine this content about clicking noise on Mitsubishi Mirage to locate the reason.

The causes for injector clicking or knocking noise Mitsubishi Mirage

A clicking or knocking noise from your injectors can be explained for different causes. In fact, the injectors of your Mitsubishi Mirage have three main missions, 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 control the air/fuel dosage and finally the homogeneity of the mixture, always with the aim of improving combustion. If one of these three functions is modified, the main functionality 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 provoke thoses knocking or clicking noises on your Mitsubishi Mirage. The main reason of these situations commonly originates from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible obstruction will inevitably result in a malfunction of the injector. If after verifying, this noise originates from another part of the engine of your Mitsubishi Mirage, have a look at this content for more infos.

The end result of injector noise on Mitsubishi Mirage

Now that we have analyzed the several reasons for injector noise on your Mitsubishi Mirage, we will end by stating the possible end result of malfunctioning one or more of your injectors. Whether only one is clogged, or broken, or your entire fuel rail is involved, you cannot escape these side effects which can almost instantly 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 felt 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 undoubtedly have a loss of power
Finally, you risk degrading one of your pistons or your engine. Poor combustion will almost instantly damage your cylinders or pistons and your engine may tighten.
Here are three little recommendations 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 swapping your diesel fuel filter regularly>
