It is hardly ever pleasant to listen an injector noise on your Mitsubishi Outlander. It is a noise that happens regularly, usually when you accelerate or your engine is idling. However, this warning sign may be linked to several sort of problems with your car injectors. It may not be anything major, but when a frequent noise arises, you have to be sure. Specifically since replacing your Mitsubishi Outlander’s injectors can be expensive. That’s why our team decided to produce this content in order to help you see more clearly, learn about the different plausible failures and identify your issue. To do this, we will first look at the normal function and usefulness of the injectors in your Mitsubishi Outlander, then at the plausible causes from which an injector noise may come.
Attributes of the injectors
Injectors are a very significant part of the operation of your engine. They were released to the modern vehicles about 20 years ago. Before their arrival, 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 collected 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 get the best possible combustion in the cylinders.
The different reasons of a clicking or knocking noise caused by the injectors of your Mitsubishi Outlander
Discovering injector noises on your Mitsubishi Outlander may originate from different sources, we will now focus on the potential triggers of these. In general, the common noise of a faulty injector is of the snap type. Here are the several origins of these noises and the solutions to be applied to prevent them. If you listen another clicking noise but it is not from your injectors, we recommend you to go through this content about clicking noise on Mitsubishi Outlander to locate the cause.
The causes for injector clicking or knocking noise Mitsubishi Outlander
A clicking or knocking noise from your injectors can be explained for different causes. In fact, the injectors of your Mitsubishi Outlander have three main missions, to control the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to facilitate its combustion. Then, its goal 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 characteristics 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 because of bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will induce thoses knocking or clicking noises on your Mitsubishi Outlander. The main cause of these situations generally comes from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible obstruction will inevitably cause a malfunction of the injector. If after checking, this noise comes from another component of the engine of your Mitsubishi Outlander, have a look at this content for more informations.
The effects of injector noise on Mitsubishi Outlander
Now that we have analyzed the diverse reasons for injector noise on your Mitsubishi Outlander, we will end by stating the possible consequences 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 consequences which can promptly become major….
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 common effects experienced by drivers is a serious 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 promptly damage your cylinders or pistons and your engine may tighten.
Here are three little suggestions to limit the risks linked 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>
