It is never enjoyable to perceive an injector noise on your Renault Twizy. It is a noise that happens continually, usually when you accelerate or your engine is idling. However, this warning sign may be relating to several types of trouble with your car injectors. It may not be anything serious, but when a recurrent noise shows up, you have to be sure. Most importantly since replacing your Renault Twizy’s injectors can be expensive. That’s why our team decided to prepare this article content in order to help you see more clearly, learn about the different conceivable failures and identify your problem. To do this, we will first look at the normal function and usefulness of the injectors in your Renault Twizy, then at the conceivable causes from which an injector noise may come.
Purposes of the injectors
Injectors are a very useful component of the operation of your engine motor. They were introduced to the modern cars about 20 years ago. Before their arrival, more conventional carburettor-type intake systems were employed, 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 received from the various sensors equipping the car (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 Renault Twizy
Discovering injector noises on your Renault Twizy may result from different origins, we will now center on the potential triggers 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 put into practice to prevent them. If you perceive another clicking noise but it is not from your injectors, we recommend you to browse this article content about clicking noise on Renault Twizy to locate the reason.
The explanations for injector clicking or knocking noise Renault Twizy
A clicking or knocking noise from your injectors can be justified by different explanations. In fact, the injectors of your Renault Twizy have three main missions, to control the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to ease its combustion. Then, its objective is to manage the air/fuel dosage and at last the homogeneity of the mixture, always with the target of improving combustion. If one of these three features 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 resulting from bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will trigger thoses knocking or clicking noises on your Renault Twizy. The main reason 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 result in a malfunction of the injector.

The side effects of injector noise on Renault Twizy
Now that we have reviewed the diverse causes for injector noise on your Renault Twizy, we will end by stating the possible end result 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 side effects which can promptly become critical….
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 effects felt by drivers is a noticeable loss of power. In fact, 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 promptly 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 changing your diesel fuel filter regularly>
