It is hardly ever pleasant to acknowledge an injector noise on your Mitsubishi Pajero. It is a noise that happens repeatedly, usually when you accelerate or your engine is idling. However, this warning sign may be linked to different types of complications with your car injectors. It may not be anything severe, but when a frequent noise arises, you have to be sure. Specifically since fixing your Mitsubishi Pajero’s injectors can be costly. That’s why our team chose to write this article content in order to support you see more clearly, learn about the different conceivable failures and distinguish your issue. To do this, we will first look at the normal running and usefulness of the injectors in your Mitsubishi Pajero, then at the conceivable reasons from which an injector noise may come.
Attributes of the injectors
Injectors are a very fundamental part of the operation of your engine motor. They were released to the modern cars 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 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 compiled from the various sensors equipping the car (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 reasons of a clicking or knocking noise caused by the injectors of your Mitsubishi Pajero
Finding out injector noises on your Mitsubishi Pajero may originate from different locations, we will now concentrate on the potential triggers of these. In most cases, the usual 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 eliminate them. If you acknowledge another clicking noise but it is not from your injectors, we advise you to read this article content about clicking noise on Mitsubishi Pajero to find the trigger.
The reasons for injector clicking or knocking noise Mitsubishi Pajero
A clicking or knocking noise from your injectors can be justified by different reasons. Indeed, the injectors of your Mitsubishi Pajero have three main tasks, to control the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to facilitate its combustion. Then, its task is to control the air/fuel dosage and at last the homogeneity of the mixture, always with the aim of improving combustion. If one of these three features is altered, 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 due to bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will provoke thoses knocking or clicking noises on your Mitsubishi Pajero. The main trigger of these problems usually comes from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible blockage will inevitably cause a malfunction of the injector. If after verifying, this noise comes from another component of the engine of your Mitsubishi Pajero, read this article content for more informations.
The consequences of injector noise on Mitsubishi Pajero
Now that we have analyzed the different reasons for injector noise on your Mitsubishi Pajero, we will end by stating the possible side effects 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 effects which can quickly 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 basic consequences noticed by drivers is a significant loss of power. Indeed, if your engine is running on 3 out of 4 cylinders for example, you will inevitably have a loss of power
Finally, you risk degrading one of your pistons or your engine. Poor combustion will quickly damage your cylinders or pistons and your engine may tighten.
Here are three little tips 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>
