It is hardly ever enjoyable to listen an injector noise on your Fiat Ducato. It is a noise that happens continually, usually when you accelerate or your engine is idling. However, this sign may be related to several types of problems with your automobile injectors. It may not be anything serious, but when a continuing noise comes out, you have to be sure. Especially since repairing your Fiat Ducato’s injectors can be expensive. That’s why our team chose to produce this content page in order to support you see more clearly, learn about the different conceivable failures and identify your problem. To do this, we will first look at the normal functioning and usefulness of the injectors in your Fiat Ducato, then at the conceivable triggers from which an injector noise may come.injector-noise-fiat-ducato

Purposes of the injectors

Injectors are a very important component of the operation of your engine unit. They were introduced 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 opportunity, 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 received from the various sensors equipping the automobile (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 triggers of a clicking or knocking noise based on the injectors of your Fiat Ducato

Finding out injector noises on your Fiat Ducato may originate from different origins, we will now concentrate on the potential triggers of these. In most cases, the regular noise of a faulty injector is of the snap type. Here are the different sources of these noises and the solutions to be adopted to stop them. If you listen another clicking noise but it is not from your injectors, we suggest you to examine this content page about clicking noise on Fiat Ducato to discover the cause.

The explanations for injector clicking or knocking noise Fiat Ducato

A clicking or knocking noise from your injectors can be explained for different explanations. In fact, the injectors of your Fiat Ducato have three main missions, to control the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to ease its combustion. Then, its task is to control the air/fuel dosage and finally the homogeneity of the mixture, always with the target of improving combustion. If one of these three characteristics is altered, the main purpose of the injectors will be disturbed 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 Fiat Ducato. The main cause of these problems usually comes from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible obstruction will inevitably end up in a malfunction of the injector. If after verifying, this noise comes from another component of the engine of your Fiat Ducato, read this content page for more infos.

The end result of injector noise on Fiat Ducato

Now that we have examined the several reasons for injector noise on your Fiat Ducato, we will end by stating the possible consequences of malfunctioning one or more of your injectors. Whether only one is obstructed, or damaged, or your entire fuel rail is involved, you cannot escape these repercussions which can fairly 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 basic effects experienced by drivers is a serious 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 fairly quickly harm your cylinders or pistons and your engine may tighten.
Here are three little suggestions 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>
