It is never enjoyable to acknowledge an injector noise on your Honda HR V. It is a noise that happens regularly, usually when you accelerate or your engine is idling. However, this warning sign may be relating to different kind of complications with your vehicle injectors. It may not be anything serious, but when a persistent noise appears, you have to be sure. Specifically since fixing your Honda HR V’s injectors can be costly. That’s why our team decided to produce this content page in order to support you see more clearly, learn about the different possible failures and distinguish your problem. To do this, we will first look at the normal function and usefulness of the injectors in your Honda HR V, then at the possible triggers from which an injector noise may come.
Functions of the injectors
Injectors are a very fundamental part of the operation of your engine motor. They were introduced 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 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 compiled from the various sensors equipping the vehicle (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 obtain the best possible combustion in the cylinders.
The different origins of a clicking or knocking noise caused by the injectors of your Honda HR V
Experiencing injector noises on your Honda HR V may come from different sources, we will now center on the potential triggers of these. In most cases, the typical noise of a faulty injector is of the snap type. Here are the different sources 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 suggest you to examine this content page about clicking noise on Honda HR V to find the cause.
The explanations for injector clicking or knocking noise Honda HR V
A clicking or knocking noise from your injectors can be explained for different explanations. Indeed, the injectors of your Honda HR V 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 mission is to deal with the air/fuel dosage and at last the homogeneity of the mixture, always with the aim 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 as a consequence of bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will induce thoses knocking or clicking noises on your Honda HR V. The main cause of these problems commonly comes from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible obstruction will inevitably lead to a malfunction of the injector. If after verifying, this noise comes from another part of the engine of your Honda HR V, check this content page for more infos.
The side effects of injector noise on Honda HR V
Now that we have reviewed the diverse causes for injector noise on your Honda HR V, we will end by stating the possible 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 critical….
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 noticed by drivers is a serious loss of power. Indeed, 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 connected 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>
