It is hardly ever enjoyable to hear an injector noise on your Jeep Wrangler. It is a noise that happens repeatedly, usually when you accelerate or your engine is idling. However, this indication may be linked to multiple kind of complications with your vehicle injectors. It may not be anything serious, but when a recurrent noise arises, you have to be sure. Specifically since replacing your Jeep Wrangler’s injectors can be expensive. That’s why our team decided to prepare this article in order to support you see more clearly, learn about the different possible failures and distinguish your trouble. To do this, we will first look at the normal running and usefulness of the injectors in your Jeep Wrangler, then at the possible triggers from which an injector noise may come.
Functions of the injectors
Injectors are a very useful component of the operation of your engine unit. They were released to the modern vehicles 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 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 compiled from the various sensors equipping the vehicle (engine temperature, acceleration level, engine speed, etc.). Their goal 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 coming from the injectors of your Jeep Wrangler
Experiencing injector noises on your Jeep Wrangler may result from different origins, we will now center on the potential causes of these. In general, 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 implemented to prevent them. If you hear another clicking noise but it is not from your injectors, we suggest you to read this article about clicking noise on Jeep Wrangler to discover the trigger.
The reasons for injector clicking or knocking noise Jeep Wrangler
A clicking or knocking noise from your injectors can be explained for different reasons. Indeed, the injectors of your Jeep Wrangler 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 control the air/fuel dosage and at last the homogeneity of the mixture, always with the aim 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 provoke thoses knocking or clicking noises on your Jeep Wrangler. The main trigger of these problems in most cases originates from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible blockage will inevitably produce a malfunction of the injector. If after checking, this noise originates from another component of the engine of your Jeep Wrangler, read this article for more informations.
The repercussions of injector noise on Jeep Wrangler
Now that we have analyzed the different reasons for injector noise on your Jeep Wrangler, 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 side effects which can promptly become severe….
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 common consequences felt by drivers is a distinctive 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 deteriorating one of your pistons or your engine. Poor combustion will promptly affect your cylinders or pistons and your engine may tighten.
Here are three little recommendations to limit the risks connected 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 swapping your diesel fuel filter regularly>
