It is never relaxing to hear an injector noise on your Renault Twingo 2. It is a noise that appears continually, usually when you accelerate or your engine is idling. However, this indicator may be related to different kind of concerns with your car injectors. It may not be anything severe, but when a frequent noise shows up, you have to be sure. Most importantly since fixing your Renault Twingo 2’s injectors can be expensive. That’s why our team decided to produce this content in order to help you see more clearly, learn about the different plausible failures and identify your problem. To do this, we will first look at the normal function and usefulness of the injectors in your Renault Twingo 2, then at the plausible reasons from which an injector noise may come.
Functions of the injectors
Injectors are a very fundamental component of the operation of your engine. They were brought in to the modern vehicles 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 ability, 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 received from the various sensors equipping the car (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 Renault Twingo 2
Listening injector noises on your Renault Twingo 2 may originate from different origins, we will now center on the potential triggers of these. In most cases, the usual noise of a faulty injector is of the snap type. Here are the several sources 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 suggest you to browse this content about clicking noise on Renault Twingo 2 to locate the trigger.
The reasons for injector clicking or knocking noise Renault Twingo 2
A clicking or knocking noise from your injectors can be justified by different reasons. In fact, the injectors of your Renault Twingo 2 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 objective is to deal with the air/fuel dosage and at last the homogeneity of the mixture, always with the aim of improving combustion. If one of these three attributes is modified, the main role of the injectors will be disturbed 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 Twingo 2. The main trigger of these situations 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 end in a malfunction of the injector.

The repercussions of injector noise on Renault Twingo 2
Now that we have examined the several reasons for injector noise on your Renault Twingo 2, 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 side effects which can quickly 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 regular repercussions experienced by drivers is a serious 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 quickly 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 swapping your diesel fuel filter regularly>
