It is hardly ever enjoyable to experience an injector noise on your Nissan Leaf. It is a noise that arises regularly, usually when you accelerate or your engine is idling. However, this indicator may be connected to several types of concerns with your vehicle injectors. It may not be anything severe, but when a recurrent noise shows up, you have to be sure. Especially since replacing your Nissan Leaf’s injectors can be expensive. That’s why our team decided to compose this content page in order to support you see more clearly, learn about the different possible failures and distinguish your issue. To do this, we will first look at the normal running and usefulness of the injectors in your Nissan Leaf, then at the possible triggers from which an injector noise may come.
Benefits of the injectors
Injectors are a very useful component of the operation of your engine. They were introduced to the modern automobiles 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 possibility, 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 collected from the various sensors equipping the vehicle (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 origins of a clicking or knocking noise coming from the injectors of your Nissan Leaf
Finding out injector noises on your Nissan Leaf may originate from different locations, we will now concentrate on the potential causes of these. Generally, the usual noise of a faulty injector is of the snap type. Here are the different origins of these noises and the solutions to be put into practice to eliminate them. If you experience another clicking noise but it is not from your injectors, we advise you to browse this content page about clicking noise on Nissan Leaf to find the cause.
The reasons for injector clicking or knocking noise Nissan Leaf
A clicking or knocking noise from your injectors can be justified by different reasons. In fact, the injectors of your Nissan Leaf 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 finally the homogeneity of the mixture, always with the objective of improving combustion. If one of these three features is modified, the main role 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 Nissan Leaf. The main cause of these problems commonly originates from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible blockage will inevitably lead to a malfunction of the injector.

The consequences of injector noise on Nissan Leaf
Now that we have reviewed the diverse reasons for injector noise on your Nissan Leaf, we will end by stating the possible side effects of malfunctioning one or more of your injectors. Whether only one is blocked, or damaged, or your entire fuel rail is involved, you cannot escape these side effects which can almost instantly become serious….
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 common repercussions felt by drivers is a severe 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 almost instantly affect your cylinders or pistons and your engine may tighten.
Here are three little tips 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 changing your diesel fuel filter regularly>
