It is hardly ever enjoyable to acknowledge an injector noise on your Toyota Aygo 2. It is a noise that appears regularly, usually when you accelerate or your engine is idling. However, this indicator may be linked to multiple sort of concerns with your automobile injectors. It may not be anything severe, but when a frequent noise comes out, you have to be sure. Specifically since replacing your Toyota Aygo 2’s injectors can be costly. That’s why our team decided to write this content page in order to help you see more clearly, learn about the different conceivable failures and distinguish your trouble. To do this, we will first look at the normal function and usefulness of the injectors in your Toyota Aygo 2, then at the conceivable causes from which an injector noise may come.
Purposes of the injectors
Injectors are a very important component of the operation of your engine. They were released to the modern automobiles 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 collected from the various sensors equipping the automobile (engine temperature, acceleration level, engine speed, etc.). Their purpose 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 causes of a clicking or knocking noise based on the injectors of your Toyota Aygo 2
Finding out injector noises on your Toyota Aygo 2 may result from different sources, we will now focus on the potential triggers of these. In general, the common noise of a faulty injector is of the snap type. Here are the several sources of these noises and the solutions to be adopted to stop 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 Toyota Aygo 2 to discover the trigger.
The causes for injector clicking or knocking noise Toyota Aygo 2
A clicking or knocking noise from your injectors can be explained for different causes. Indeed, the injectors of your Toyota Aygo 2 have three main missions, to control the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to facilitate its combustion. Then, its mission is to manage the air/fuel dosage and finally the homogeneity of the mixture, always with the objective of improving combustion. If one of these three tasks is altered, the main functionality 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 Toyota Aygo 2. The main trigger of these situations commonly originates from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible obstruction will inevitably end up in a malfunction of the injector. If after checking, this noise originates from another component of the engine of your Toyota Aygo 2, read this content page for more infos.
The effects of injector noise on Toyota Aygo 2
Now that we have analyzed the diverse reasons for injector noise on your Toyota Aygo 2, we will end by stating the possible effects of malfunctioning one or more of your injectors. Whether only one is blocked, or damaged, or your entire fuel rail is involved, you cannot escape these consequences which can promptly become considerable….
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 regular consequences felt by drivers is a noticeable loss of power. Indeed, if your engine is running on 3 out of 4 cylinders for example, you will undoubtedly have a loss of power
Finally, you risk degrading one of your pistons or your engine. Poor combustion will promptly harm your cylinders or pistons and your engine may tighten.
Here are three little tips 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 changing your diesel fuel filter regularly>
