It is rarely ever relaxing to acknowledge an injector noise on your Mercury Mariner. It is a noise that arises regularly, usually when you accelerate or your engine is idling. However, this sign may be connected to multiple sort of complications with your automobile injectors. It may not be anything major, but when a recurrent noise appears, you have to be sure. Specifically since replacing your Mercury Mariner’s injectors can be costly. That’s why our team decided to write this article in order to support you see more clearly, learn about the different plausible failures and determine your issue. To do this, we will first look at the normal function and usefulness of the injectors in your Mercury Mariner, then at the plausible causes from which an injector noise may come.
Functions of the injectors
Injectors are a very vital element of the operation of your engine unit. They were introduced 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 obtained from the various sensors equipping the automobile (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 obtain the best possible combustion in the cylinders.
The different origins of a clicking or knocking noise caused by the injectors of your Mercury Mariner
Hearing injector noises on your Mercury Mariner may result from different locations, we will now focus on the potential causes of these. In most cases, the typical noise of a faulty injector is of the snap type. Here are the several origins of these noises and the solutions to be adopted to stop them. If you acknowledge another clicking noise but it is not from your injectors, we encourage you to go through this article about clicking noise on Mercury Mariner to find the reason.
The explanations for injector clicking or knocking noise Mercury Mariner
A clicking or knocking noise from your injectors can be justified by different explanations. In fact, the injectors of your Mercury Mariner 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 task is to deal with the air/fuel dosage and at last the homogeneity of the mixture, always with the goal of improving combustion. If one of these three attributes 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 trigger thoses knocking or clicking noises on your Mercury Mariner. The main reason of these concerns 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 cause a malfunction of the injector.

The consequences of injector noise on Mercury Mariner
Now that we have reviewed the several reasons for injector noise on your Mercury Mariner, we will end by stating the possible side effects of malfunctioning one or more of your injectors. Whether only one is obstructed, or damaged, or your entire fuel rail is involved, you cannot escape these effects which can fairly 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 distinctive 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 fairly quickly harm your cylinders or pistons and your engine may tighten.
Here are three little suggestions to limit the risks relating 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>
