It is rarely ever pleasurable to perceive an injector noise on your Nissan Pulsar. It is a noise that happens continually, 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 severe, but when a continuing noise comes out, you have to be sure. Especially since replacing your Nissan Pulsar’s injectors can be costly. That’s why our team chose to compose this content page in order to help you see more clearly, learn about the different possible failures and identify your issue. To do this, we will first look at the normal function and usefulness of the injectors in your Nissan Pulsar, then at the possible causes from which an injector noise may come.
Purposes of the injectors
Injectors are a very fundamental element of the operation of your engine. They were launched to the modern vehicles 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 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 collected 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 get the best possible combustion in the cylinders.
The different reasons of a clicking or knocking noise based on the injectors of your Nissan Pulsar
Experiencing injector noises on your Nissan Pulsar may originate from different sources, we will now look into the potential causes of these. In general, the usual noise of a faulty injector is of the snap type. Here are the different sources of these noises and the solutions to be implemented to stop them. If you perceive another clicking noise but it is not from your injectors, we recommend you to go through this content page about clicking noise on Nissan Pulsar to discover the reason.
The causes for injector clicking or knocking noise Nissan Pulsar
A clicking or knocking noise from your injectors can be justified by different causes. In fact, the injectors of your Nissan Pulsar 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 objective of improving combustion. If one of these three characteristics 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 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 Pulsar. The main reason of these situations commonly comes from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible blockage will inevitably end up in a malfunction of the injector. If after checking, this noise comes from another component of the engine of your Nissan Pulsar, read this content page for more informations.
The end result of injector noise on Nissan Pulsar
Now that we have reviewed the diverse causes for injector noise on your Nissan Pulsar, we will end by stating the possible consequences 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 effects which can almost instantly become major….
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 felt by drivers is a serious loss of power. In fact, if your engine is running on 3 out of 4 cylinders for example, you will surely 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 suggestions 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 swapping your diesel fuel filter regularly>
