It is never relaxing to perceive an injector noise on your Honda Accord. It is a noise that comes up frequently, usually when you accelerate or your engine is idling. However, this warning sign may be relating to several types of concerns with your vehicle injectors. It may not be anything major, but when a recurrent noise arises, you have to be sure. Most importantly since replacing your Honda Accord’s injectors can be costly. That’s why our team decided to prepare this content in order to help 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 Accord, then at the possible triggers from which an injector noise may come.injector-noise-honda-accord

Purposes of the injectors

Injectors are a very important element of the operation of your engine motor. They were released to the modern cars about 20 years ago. Before their introduction, 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 accumulated 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 get the best possible combustion in the cylinders.

The different origins of a clicking or knocking noise coming from the injectors of your Honda Accord

Experiencing injector noises on your Honda Accord may result from different sources, we will now concentrate on the potential triggers of these. Generally, the typical 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 get rid of them. If you perceive another clicking noise but it is not from your injectors, we suggest you to go through this content about clicking noise on Honda Accord to find the cause.

The reasons for injector clicking or knocking noise Honda Accord

A clicking or knocking noise from your injectors can be explained for different reasons. In fact, the injectors of your Honda Accord have three main missions, to control the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to ease its combustion. Then, its mission is to control the air/fuel dosage and at last the homogeneity of the mixture, always with the target of improving combustion. If one of these three tasks is altered, 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 due to bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will induce thoses knocking or clicking noises on your Honda Accord. The main cause of these trouble in most cases comes from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible obstruction will inevitably end in a malfunction of the injector.

The consequences of injector noise on Honda Accord

Now that we have examined the diverse causes for injector noise on your Honda Accord, we will end by stating the possible side effects 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 considerable….
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 common effects felt 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 almost instantly affect your cylinders or pistons and your engine may tighten.
Here are three little tips 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 changing your diesel fuel filter regularly>
