It is rarely ever pleasant to perceive an injector noise on your Ram ProMaster City. It is a noise that comes up continually, usually when you accelerate or your engine is idling. However, this warning sign may be related to several types of complications with your automobile injectors. It may not be anything major, but when a repeated noise happens, you have to be sure. Most importantly since fixing your Ram ProMaster City’s injectors can be costly. That’s why our team decided to compose this article content in order to support you see more clearly, learn about the different possible failures and establish your problem. To do this, we will first look at the normal running and usefulness of the injectors in your Ram ProMaster City, then at the possible causes from which an injector noise may come.injector-noise-ram-promaster-city

Functions of the injectors

Injectors are a very significant component of the operation of your engine. They were launched to the modern automobiles 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 precisely (quantity of fuel injected, air/fuel mixture) via the analysis of the data accumulated from the various sensors equipping the automobile (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 origins of a clicking or knocking noise coming from the injectors of your Ram ProMaster City

Hearing injector noises on your Ram ProMaster City may originate from different origins, we will now look into the potential causes of these. Generally, the common noise of a faulty injector is of the snap type. Here are the different origins of these noises and the solutions to be implemented to get rid of them. If you perceive another clicking noise but it is not from your injectors, we suggest you to browse this article content about clicking noise on Ram ProMaster City to find the reason.

The explanations for injector clicking or knocking noise Ram ProMaster City

A clicking or knocking noise from your injectors can be explained for different explanations. Indeed, the injectors of your Ram ProMaster City have three main missions, to manage the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to ease its combustion. Then, its objective is to control the air/fuel dosage and at last the homogeneity of the mixture, always with the goal of improving combustion. If one of these three functions is modified, 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 induce thoses knocking or clicking noises on your Ram ProMaster City. The main reason of these situations commonly originates from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible blockage will inevitably end up in a malfunction of the injector. If after checking, this noise originates from another element of the engine of your Ram ProMaster City, have a look at this article content for more infos.

The consequences of injector noise on Ram ProMaster City

Now that we have analyzed the diverse reasons for injector noise on your Ram ProMaster City, we will end by stating the possible side effects of malfunctioning one or more of your injectors. Whether only one is blocked, or broken, or your entire fuel rail is involved, you cannot escape these consequences which can almost instantly become severe….
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 basic repercussions noticed 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 degrading 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 associated with 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 changing your diesel fuel filter regularly>
