It is never pleasurable to hear an injector noise on your Mercury Grand Marquis. It is a noise that comes up regularly, usually when you accelerate or your engine is idling. However, this warning sign may be relating to several kind of problems with your vehicle injectors. It may not be anything serious, but when a persistent noise arises, you have to be sure. Specifically since replacing your Mercury Grand Marquis’s injectors can be expensive. That’s why our team chose to prepare this content page in order to help you see more clearly, learn about the different plausible failures and determine your trouble. To do this, we will first look at the normal function and usefulness of the injectors in your Mercury Grand Marquis, then at the plausible reasons from which an injector noise may come.
Attributes of the injectors
Injectors are a very significant component of the operation of your engine motor. They were launched to the modern vehicles about 20 years ago. Before their introduction, 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 obtained from the various sensors equipping the vehicle (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 based on the injectors of your Mercury Grand Marquis
Experiencing injector noises on your Mercury Grand Marquis may come from different origins, we will now center on the potential causes of these. In most cases, 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 eliminate them. If you hear another clicking noise but it is not from your injectors, we encourage you to browse this content page about clicking noise on Mercury Grand Marquis to discover the cause.
The causes for injector clicking or knocking noise Mercury Grand Marquis
A clicking or knocking noise from your injectors can be justified by different causes. Indeed, the injectors of your Mercury Grand Marquis have three main missions, to manage the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to ease its combustion. Then, its goal is to manage the air/fuel dosage and finally the homogeneity of the mixture, always with the objective of improving combustion. If one of these three tasks is altered, the main purpose of the injectors will be disturbed and this will lead to poor combustion. This bad combustion will be a violent explosion in the cylinders as a consequence of bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will provoke thoses knocking or clicking noises on your Mercury Grand Marquis. The main cause of these trouble in most cases comes from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible blockage will inevitably lead to a malfunction of the injector. If after checking, this noise comes from another element of the engine of your Mercury Grand Marquis, read this content page for more informations.
The effects of injector noise on Mercury Grand Marquis
Now that we have analyzed the several reasons for injector noise on your Mercury Grand Marquis, 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 repercussions which can almost instantly become considerable….
First, you risk destroying your exhaust system 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 consequences noticed by drivers is a distinctive loss of power. Indeed, if your engine is running on 3 out of 4 cylinders for example, you will obviously have a loss of power
Finally, you risk degrading one of your pistons or your engine. Poor combustion will almost instantly affect 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>
