It is hardly ever relaxing to hear an injector noise on your Chrysler Pacifica. It is a noise that appears frequently, usually when you accelerate or your engine is idling. However, this symptom may be related to multiple sort of complications with your automobile injectors. It may not be anything major, but when a persistent noise shows up, you have to be sure. Most importantly since repairing your Chrysler Pacifica’s injectors can be expensive. That’s why our team chose to compose this content page 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 Chrysler Pacifica, then at the possible causes from which an injector noise may come.injector-noise-chrysler-pacifica

Attributes of the injectors

Injectors are a very important element of the operation of your engine unit. They were brought in 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 ability, 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 compiled from the various sensors equipping the automobile (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 obtain the best possible combustion in the cylinders.

The different origins of a clicking or knocking noise coming from the injectors of your Chrysler Pacifica

Experiencing injector noises on your Chrysler Pacifica may come from different locations, we will now concentrate on the potential causes of these. In general, 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 adopted to stop them. If you hear another clicking noise but it is not from your injectors, we recommend you to read this content page about clicking noise on Chrysler Pacifica to discover the reason.

The reasons for injector clicking or knocking noise Chrysler Pacifica

A clicking or knocking noise from your injectors can be explained for different reasons. In fact, the injectors of your Chrysler Pacifica have three main missions, to manage the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to ease its combustion. Then, its objective is to control the air/fuel dosage and at last the homogeneity of the mixture, always with the target of improving combustion. If one of these three attributes is altered, the main purpose of the injectors will be disrupted and this will lead to poor combustion. This bad combustion will be a violent explosion in the cylinders due to bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will provoke thoses knocking or clicking noises on your Chrysler Pacifica. The main reason 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 result in a malfunction of the injector. If after checking, this noise originates from another component of the engine of your Chrysler Pacifica, read this content page for more infos.

The consequences of injector noise on Chrysler Pacifica

Now that we have analyzed the several reasons for injector noise on your Chrysler Pacifica, we will end by stating the possible effects of malfunctioning one or more of your injectors. Whether only one is clogged, or damaged, or your entire fuel rail is involved, you cannot escape these consequences which can promptly 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 effects noticed by drivers is a significant loss of power. In fact, 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 damage 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>
