It is never pleasant to listen an injector noise on your Nissan Qashqai. It is a noise that happens continually, usually when you accelerate or your engine is idling. However, this symptom may be relating to several types of problems with your car injectors. It may not be anything major, but when a frequent noise appears, you have to be sure. Most importantly since replacing your Nissan Qashqai’s injectors can be expensive. That’s why our team chose to compose this content in order to support you see more clearly, learn about the different conceivable failures and distinguish your trouble. To do this, we will first look at the normal function and usefulness of the injectors in your Nissan Qashqai, then at the conceivable triggers from which an injector noise may come.
Attributes of the injectors
Injectors are a very useful component of the operation of your engine. They were released 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 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 aim 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 causes of a clicking or knocking noise based on the injectors of your Nissan Qashqai
Discovering injector noises on your Nissan Qashqai may result from different sources, we will now center on the potential causes of these. In general, the common noise of a faulty injector is of the snap type. Here are the several origins of these noises and the solutions to be implemented to get rid of them. If you listen another clicking noise but it is not from your injectors, we encourage you to examine this content about clicking noise on Nissan Qashqai to find the cause.
The reasons for injector clicking or knocking noise Nissan Qashqai
A clicking or knocking noise from your injectors can be explained for different reasons. In fact, the injectors of your Nissan Qashqai have three main tasks, to manage the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to facilitate its combustion. Then, its objective is to manage the air/fuel dosage and finally the homogeneity of the mixture, always with the goal of improving combustion. If one of these three functions is altered, 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 because of bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will induce thoses knocking or clicking noises on your Nissan Qashqai. The main cause of these concerns usually originates from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible obstruction will inevitably result in a malfunction of the injector. If after checking, this noise originates from another element of the engine of your Nissan Qashqai, read this content for more informations.
The end result of injector noise on Nissan Qashqai
Now that we have examined the several reasons for injector noise on your Nissan Qashqai, we will end by stating the possible effects 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 consequences 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 known consequences experienced by drivers is a significant loss of power. In fact, if your engine is running on 3 out of 4 cylinders for example, you will undoubtedly have a loss of power
Finally, you risk deteriorating one of your pistons or your engine. Poor combustion will quickly affect your cylinders or pistons and your engine may tighten.
Here are three little tips to limit the risks associated with 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>
