It is never pleasant to notice an injector noise on your Nissan Almera. It is a noise that appears repeatedly, usually when you accelerate or your engine is idling. However, this indicator may be connected to different sort of complications with your car injectors. It may not be anything serious, but when a persistent noise shows up, you have to be sure. Especially since replacing your Nissan Almera’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 conceivable failures and identify your problem. To do this, we will first look at the normal functioning and usefulness of the injectors in your Nissan Almera, then at the conceivable triggers from which an injector noise may come.
Benefits of the injectors
Injectors are a very significant element of the operation of your engine. They were launched to the modern cars about 20 years ago. Before their appearance, 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 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 reasons of a clicking or knocking noise caused by the injectors of your Nissan Almera
Experiencing injector noises on your Nissan Almera may come from different origins, we will now concentrate on the potential causes of these. In general, the common 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 get rid of them. If you notice another clicking noise but it is not from your injectors, we suggest you to examine this content about clicking noise on Nissan Almera to locate the reason.
The explanations for injector clicking or knocking noise Nissan Almera
A clicking or knocking noise from your injectors can be explained for different explanations. Indeed, the injectors of your Nissan Almera have three main missions, to manage the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to facilitate its combustion. Then, its task is to control the air/fuel dosage and finally the homogeneity of the mixture, always with the target of improving combustion. If one of these three tasks is altered, the main purpose of the injectors will be disturbed 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 provoke thoses knocking or clicking noises on your Nissan Almera. The main reason of these concerns 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 result in a malfunction of the injector. If after verifying, this noise originates from another component of the engine of your Nissan Almera, check this content for more informations.
The effects of injector noise on Nissan Almera
Now that we have examined the diverse reasons for injector noise on your Nissan Almera, we will end by stating the possible consequences 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 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 known consequences felt by drivers is a distinctive loss of power. Indeed, 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 almost instantly affect your cylinders or pistons and your engine may tighten.
Here are three little suggestions 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>
