It is rarely ever relaxing to notice an injector noise on your Suzuki Alto. It is a noise that appears frequently, usually when you accelerate or your engine is idling. However, this warning sign may be linked to different sort of complications with your vehicle injectors. It may not be anything severe, but when a persistent noise happens, you have to be sure. Especially since replacing your Suzuki Alto’s injectors can be costly. That’s why our team chose to produce this article content in order to help you see more clearly, learn about the different possible failures and identify your issue. To do this, we will first look at the normal functioning and usefulness of the injectors in your Suzuki Alto, then at the possible causes from which an injector noise may come.
Benefits of the injectors
Injectors are a very significant part of the operation of your engine unit. They were brought in to the modern cars 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 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 received from the various sensors equipping the vehicle (engine temperature, acceleration level, engine speed, etc.). Their objective 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 triggers of a clicking or knocking noise coming from the injectors of your Suzuki Alto
Experiencing injector noises on your Suzuki Alto may originate from different locations, we will now focus on the potential triggers of these. Generally, the regular noise of a faulty injector is of the snap type. Here are the different origins of these noises and the solutions to be implemented to stop them. If you notice another clicking noise but it is not from your injectors, we suggest you to examine this article content about clicking noise on Suzuki Alto to find the cause.
The reasons for injector clicking or knocking noise Suzuki Alto
A clicking or knocking noise from your injectors can be explained for different reasons. Indeed, the injectors of your Suzuki Alto have three main tasks, to control the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to ease its combustion. Then, its task is to deal with the air/fuel dosage and finally the homogeneity of the mixture, always with the target of improving combustion. If one of these three attributes is modified, 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 resulting from bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will trigger thoses knocking or clicking noises on your Suzuki Alto. The main cause of these situations generally comes from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible blockage will inevitably lead to a malfunction of the injector. If after checking, this noise comes from another component of the engine of your Suzuki Alto, have a look at this article content for more informations.
The repercussions of injector noise on Suzuki Alto
Now that we have reviewed the several causes for injector noise on your Suzuki Alto, we will end by stating the possible side effects 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 repercussions which can almost instantly 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 common consequences experienced by drivers is a noticeable 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 almost instantly damage your cylinders or pistons and your engine may tighten.
Here are three little suggestions to limit the risks relating 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 swapping your diesel fuel filter regularly>
