It is never pleasurable to listen an injector noise on your Suzuki Jimny. It is a noise that arises frequently, usually when you accelerate or your engine is idling. However, this warning sign may be connected to different types of trouble with your car injectors. It may not be anything serious, but when a repeated noise arises, you have to be sure. Especially since replacing your Suzuki Jimny’s injectors can be costly. That’s why our team decided to prepare this article in order to help you see more clearly, learn about the different conceivable failures and establish your trouble. To do this, we will first look at the normal functioning and usefulness of the injectors in your Suzuki Jimny, then at the conceivable reasons from which an injector noise may come.
Functions of the injectors
Injectors are a very useful part of the operation of your engine. They were introduced 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 possibility, 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 obtained from the various sensors equipping the car (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 origins of a clicking or knocking noise caused by the injectors of your Suzuki Jimny
Hearing injector noises on your Suzuki Jimny may originate 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 different origins of these noises and the solutions to be put into practice to prevent them. If you listen another clicking noise but it is not from your injectors, we recommend you to go through this article about clicking noise on Suzuki Jimny to locate the trigger.
The explanations for injector clicking or knocking noise Suzuki Jimny
A clicking or knocking noise from your injectors can be justified by different explanations. In fact, the injectors of your Suzuki Jimny have three main tasks, to control the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to facilitate its combustion. Then, its mission is to deal with the air/fuel dosage and at last the homogeneity of the mixture, always with the goal of improving combustion. If one of these three attributes is modified, the main functionality of the injectors will be disrupted 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 provoke thoses knocking or clicking noises on your Suzuki Jimny. The main trigger of these situations commonly 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 part of the engine of your Suzuki Jimny, have a look at this article for more informations.
The side effects of injector noise on Suzuki Jimny
Now that we have analyzed the different causes for injector noise on your Suzuki Jimny, 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 fairly quickly become critical….
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 felt by drivers is a distinctive loss of power. In fact, if your engine is running on 3 out of 4 cylinders for example, you will surely have a loss of power
Finally, you risk deteriorating one of your pistons or your engine. Poor combustion will fairly quickly damage 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>
