It is hardly ever pleasurable to listen an injector noise on your Dodge Grand Caravan. It is a noise that happens continually, usually when you accelerate or your engine is idling. However, this indicator may be linked to different sort of complications with your car injectors. It may not be anything serious, but when a continuing noise appears, you have to be sure. Specifically since replacing your Dodge Grand Caravan’s injectors can be costly. That’s why our team decided to produce this article in order to help you see more clearly, learn about the different conceivable failures and determine your trouble. To do this, we will first look at the normal functioning and usefulness of the injectors in your Dodge Grand Caravan, then at the conceivable reasons from which an injector noise may come.injector-noise-dodge-grand-caravan

Attributes of the injectors

Injectors are a very important element 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 precisely (quantity of fuel injected, air/fuel mixture) via the analysis of the data received from the various sensors equipping the car (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 obtain the best possible combustion in the cylinders.

The different origins of a clicking or knocking noise based on the injectors of your Dodge Grand Caravan

Listening injector noises on your Dodge Grand Caravan may come 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 put into practice to get rid of them. If you listen another clicking noise but it is not from your injectors, we recommend you to browse this article about clicking noise on Dodge Grand Caravan to locate the reason.

The causes for injector clicking or knocking noise Dodge Grand Caravan

A clicking or knocking noise from your injectors can be justified by different causes. Indeed, the injectors of your Dodge Grand Caravan have three main missions, to control the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to facilitate its combustion. Then, its task is to deal with the air/fuel dosage and finally the homogeneity of the mixture, always with the aim of improving combustion. If one of these three features 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 trigger thoses knocking or clicking noises on your Dodge Grand Caravan. The main reason of these trouble 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 lead to a malfunction of the injector.

The effects of injector noise on Dodge Grand Caravan

Now that we have analyzed the different reasons for injector noise on your Dodge Grand Caravan, 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 quickly become critical….
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 repercussions felt by drivers is a serious 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 quickly damage your cylinders or pistons and your engine may tighten.
Here are three little suggestions 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 swapping your diesel fuel filter regularly>
