It is rarely ever enjoyable to perceive an injector noise on your Mitsubishi Lancer. It is a noise that arises continually, usually when you accelerate or your engine is idling. However, this symptom may be related to several sort of problems with your car injectors. It may not be anything major, but when a continuing noise happens, you have to be sure. Most importantly since repairing your Mitsubishi Lancer’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 conceivable failures and establish your problem. To do this, we will first look at the normal running and usefulness of the injectors in your Mitsubishi Lancer, then at the conceivable triggers from which an injector noise may come.injector-noise-mitsubishi-lancer

Functions of the injectors

Injectors are a very fundamental element of the operation of your engine unit. They were released to the modern automobiles 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 precisely (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 purpose 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 coming from the injectors of your Mitsubishi Lancer

Hearing injector noises on your Mitsubishi Lancer may originate from different locations, we will now center on the potential triggers 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 eliminate them. If you perceive another clicking noise but it is not from your injectors, we suggest you to go through this content about clicking noise on Mitsubishi Lancer to find the reason.

The reasons for injector clicking or knocking noise Mitsubishi Lancer

A clicking or knocking noise from your injectors can be explained for different reasons. Indeed, the injectors of your Mitsubishi Lancer 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 mission is to deal with 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 altered, the main functionality 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 induce thoses knocking or clicking noises on your Mitsubishi Lancer. The main reason of these situations usually originates from a particle that gets into the injectors. The precision 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 part of the engine of your Mitsubishi Lancer, read this content for more informations.

The side effects of injector noise on Mitsubishi Lancer

Now that we have analyzed the different reasons for injector noise on your Mitsubishi Lancer, we will end by stating the possible side effects 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 almost instantly become serious….
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 consequences felt by drivers is a noticeable loss of power. Indeed, 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 almost instantly harm 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 swapping your diesel fuel filter regularly>
