It is rarely ever pleasurable to acknowledge an injector noise on your Ram ProMaster. It is a noise that comes up regularly, usually when you accelerate or your engine is idling. However, this symptom may be linked to multiple types of problems with your vehicle injectors. It may not be anything major, but when a continuing noise arises, you have to be sure. Specifically since fixing your Ram ProMaster’s injectors can be expensive. That’s why our team chose to prepare this content page 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 Ram ProMaster, then at the plausible triggers from which an injector noise may come.
Attributes of the injectors
Injectors are a very useful part of the operation of your engine unit. They were launched to the modern cars 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 collected from the various sensors equipping the vehicle (engine temperature, acceleration level, engine speed, etc.). Their aim 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 Ram ProMaster
Finding out injector noises on your Ram ProMaster may result from different locations, we will now focus on the potential causes of these. Generally, the typical noise of a faulty injector is of the snap type. Here are the several sources of these noises and the solutions to be put into practice to eliminate them. If you acknowledge another clicking noise but it is not from your injectors, we recommend you to go through this content page about clicking noise on Ram ProMaster to locate the trigger.
The explanations for injector clicking or knocking noise Ram ProMaster
A clicking or knocking noise from your injectors can be explained for different explanations. Indeed, the injectors of your Ram ProMaster have three main missions, to control the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to ease its combustion. Then, its task is to deal with the air/fuel dosage and finally the homogeneity of the mixture, always with the goal of improving combustion. If one of these three attributes is modified, 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 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. The main trigger of these concerns commonly 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 Ram ProMaster, check this content page for more infos.
The effects of injector noise on Ram ProMaster
Now that we have analyzed the diverse causes for injector noise on your Ram ProMaster, we will end by stating the possible effects of malfunctioning one or more of your injectors. Whether only one is obstructed, or broken, or your entire fuel rail is involved, you cannot escape these repercussions which can quickly become critical….
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 repercussions felt by drivers is a noticeable 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 deteriorating 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 recommendations 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>
