It is never relaxing to experience an injector noise on your Renault Master. It is a noise that happens continually, usually when you accelerate or your engine is idling. However, this warning sign may be connected to multiple kind of problems with your car injectors. It may not be anything severe, but when a continuing noise shows up, you have to be sure. Most importantly since repairing your Renault Master’s injectors can be expensive. That’s why our team decided to create this content in order to help you see more clearly, learn about the different plausible failures and distinguish your issue. To do this, we will first look at the normal functioning and usefulness of the injectors in your Renault Master, then at the plausible reasons from which an injector noise may come.
Purposes of the injectors
Injectors are a very important part of the operation of your engine. They were released to the modern automobiles about 20 years ago. Before their arrival, 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 possibility, 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 obtained from the various sensors equipping the car (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 get the best possible combustion in the cylinders.
The different reasons of a clicking or knocking noise caused by the injectors of your Renault Master
Discovering injector noises on your Renault Master may come from different origins, we will now concentrate on the potential causes of these. Generally, the typical noise of a faulty injector is of the snap type. Here are the different sources of these noises and the solutions to be applied to eliminate them. If you experience another clicking noise but it is not from your injectors, we recommend you to read this content about clicking noise on Renault Master to discover the trigger.
The reasons for injector clicking or knocking noise Renault Master
A clicking or knocking noise from your injectors can be explained for different reasons. In fact, the injectors of your Renault Master have three main tasks, to manage the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to ease its combustion. Then, its goal is to control the air/fuel dosage and at last the homogeneity of the mixture, always with the target of improving combustion. If one of these three tasks is modified, the main purpose of the injectors will be disrupted and this will lead to poor combustion. This bad combustion will be a violent explosion in the cylinders because of bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will provoke thoses knocking or clicking noises on your Renault Master. The main trigger of these problems 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 produce a malfunction of the injector.

The side effects of injector noise on Renault Master
Now that we have examined the several reasons for injector noise on your Renault Master, we will end by stating the possible end result 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 side effects which can promptly 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 regular repercussions experienced 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 degrading one of your pistons or your engine. Poor combustion will promptly 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 changing your diesel fuel filter regularly>
