It is hardly ever relaxing to experience an injector noise on your Honda Civic. It is a noise that arises frequently, usually when you accelerate or your engine is idling. However, this warning sign may be connected to several types of trouble with your automobile injectors. It may not be anything major, but when a continuing noise appears, you have to be sure. Most importantly since fixing your Honda Civic’s injectors can be costly. That’s why our team chose to write this article content in order to support you see more clearly, learn about the different plausible failures and determine your issue. To do this, we will first look at the normal functioning and usefulness of the injectors in your Honda Civic, then at the plausible triggers from which an injector noise may come.injector-noise-honda-civic

Benefits of the injectors

Injectors are a very vital element of the operation of your engine. They were released to the modern automobiles about 20 years ago. Before their introduction, 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 ability, thanks to the injectors pump, to control electronically each stage of the intake process very accurately (quantity of fuel injected, air/fuel mixture) via the analysis of the data received from the various sensors equipping the automobile (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 Civic

Discovering injector noises on your Honda Civic may result from different origins, we will now look into the potential triggers of these. Generally, the regular noise of a faulty injector is of the snap type. Here are the several origins of these noises and the solutions to be adopted to get rid of them. If you experience another clicking noise but it is not from your injectors, we advise you to examine this article content about clicking noise on Honda Civic to discover the reason.

The reasons for injector clicking or knocking noise Honda Civic

A clicking or knocking noise from your injectors can be justified by different reasons. In fact, the injectors of your Honda Civic 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 goal is to deal with the air/fuel dosage and finally the homogeneity of the mixture, always with the objective of improving combustion. If one of these three features 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 Honda Civic. The main reason of these trouble 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 produce a malfunction of the injector.

The repercussions of injector noise on Honda Civic

Now that we have analyzed the diverse causes for injector noise on your Honda Civic, we will end by stating the possible side effects of malfunctioning one or more of your injectors. Whether only one is clogged, or damaged, or your entire fuel rail is involved, you cannot escape these side effects which can almost instantly become major….
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 effects noticed by drivers is a severe loss of power. In fact, if your engine is running on 3 out of 4 cylinders for example, you will inevitably have a loss of power
Finally, you risk deteriorating one of your pistons or your engine. Poor combustion will almost instantly harm your cylinders or pistons and your engine may tighten.
Here are three little recommendations 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>
