It is rarely ever relaxing to listen to an injector noise on your Toyota Verso. It is a noise that arises regularly, usually when you accelerate or your engine is idling. However, this indication may be connected to several types of concerns with your vehicle injectors. It may not be anything severe, but when a continuing noise comes out, you have to be sure. Most importantly since replacing your Toyota Verso’s injectors can be costly. That’s why our team decided to produce this article in order to help you see more clearly, learn about the different possible failures and identify your problem. To do this, we will first look at the normal function and usefulness of the injectors in your Toyota Verso, then at the possible reasons from which an injector noise may come.injector-noise-toyota-verso

Attributes of the injectors

Injectors are a very fundamental component of the operation of your engine unit. They were brought in 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 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 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 caused by the injectors of your Toyota Verso

Discovering injector noises on your Toyota Verso may come from different origins, we will now focus on the potential triggers of these. In general, the usual noise of a faulty injector is of the snap type. Here are the several sources of these noises and the solutions to be put into practice to prevent them. If you listen to another clicking noise but it is not from your injectors, we encourage you to examine this article about clicking noise on Toyota Verso to discover the reason.

The explanations for injector clicking or knocking noise Toyota Verso

A clicking or knocking noise from your injectors can be justified by different explanations. Indeed, the injectors of your Toyota Verso 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 objective is to manage the air/fuel dosage and finally the homogeneity of the mixture, always with the goal of improving combustion. If one of these three features 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 as a consequence of bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will trigger thoses knocking or clicking noises on your Toyota Verso. 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 verifying, this noise comes from another component of the engine of your Toyota Verso, have a look at this article for more informations.

The end result of injector noise on Toyota Verso

Now that we have examined the diverse causes for injector noise on your Toyota Verso, we will end by stating the possible consequences of malfunctioning one or more of your injectors. Whether only one is blocked, or broken, or your entire fuel rail is involved, you cannot escape these side effects which can quickly become serious….
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 basic effects felt by drivers is a significant 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 quickly harm 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>
