It is rarely ever enjoyable to acknowledge an injector noise on your Nissan NV200. It is a noise that arises repeatedly, usually when you accelerate or your engine is idling. However, this sign may be related to different kind of complications with your vehicle injectors. It may not be anything serious, but when a repeated noise arises, you have to be sure. Especially since repairing your Nissan NV200’s injectors can be costly. That’s why our team decided to produce this article content in order to help you see more clearly, learn about the different possible failures and determine your trouble. To do this, we will first look at the normal functioning and usefulness of the injectors in your Nissan NV200, then at the possible reasons from which an injector noise may come.
Benefits of the injectors
Injectors are a very vital part of the operation of your engine. They were launched to the modern automobiles about 20 years ago. Before their appearance, 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 precisely (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 goal 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 triggers of a clicking or knocking noise coming from the injectors of your Nissan NV200
Listening injector noises on your Nissan NV200 may result from different origins, we will now look into the potential causes of these. Generally, the usual noise of a faulty injector is of the snap type. Here are the several origins of these noises and the solutions to be put into practice to prevent them. If you acknowledge another clicking noise but it is not from your injectors, we advise you to read this article content about clicking noise on Nissan NV200 to find the trigger.
The reasons for injector clicking or knocking noise Nissan NV200
A clicking or knocking noise from your injectors can be explained for different reasons. In fact, the injectors of your Nissan NV200 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 mission 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 modified, 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 because of bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will trigger thoses knocking or clicking noises on your Nissan NV200. The main trigger of these situations usually comes from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible obstruction will inevitably end up in a malfunction of the injector. If after checking, this noise comes from another element of the engine of your Nissan NV200, check this article content for more infos.
The side effects of injector noise on Nissan NV200
Now that we have reviewed the several causes for injector noise on your Nissan NV200, we will end by stating the possible side effects of malfunctioning one or more of your injectors. Whether only one is obstructed, or broken, or your entire fuel rail is involved, you cannot escape these repercussions which can fairly 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 known consequences experienced 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 obviously have a loss of power
Finally, you risk degrading one of your pistons or your engine. Poor combustion will fairly quickly 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>
