It is rarely ever pleasurable to hear an injector noise on your Mercedes Vito. It is a noise that comes up repeatedly, usually when you accelerate or your engine is idling. However, this warning sign may be linked to several sort of complications with your automobile injectors. It may not be anything severe, but when a recurrent noise happens, you have to be sure. Especially since repairing your Mercedes Vito’s injectors can be costly. That’s why our team chose to produce this article content in order to help you see more clearly, learn about the different conceivable failures and identify your issue. To do this, we will first look at the normal running and usefulness of the injectors in your Mercedes Vito, then at the conceivable reasons from which an injector noise may come.
Benefits of the injectors
Injectors are a very significant part of the operation of your engine motor. 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 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 reasons of a clicking or knocking noise based on the injectors of your Mercedes Vito
Listening injector noises on your Mercedes Vito may come from different sources, we will now center on the potential triggers of these. Generally, the typical noise of a faulty injector is of the snap type. Here are the several sources of these noises and the solutions to be applied to get rid of them. If you hear another clicking noise but it is not from your injectors, we suggest you to browse this article content about clicking noise on Mercedes Vito to locate the cause.
The reasons for injector clicking or knocking noise Mercedes Vito
A clicking or knocking noise from your injectors can be explained for different reasons. Indeed, the injectors of your Mercedes Vito 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 mission is to control the air/fuel dosage and finally the homogeneity of the mixture, always with the goal of improving combustion. If one of these three functions 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 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 Mercedes Vito. The main cause of these concerns 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 end up in a malfunction of the injector. If after verifying, this noise originates from another element of the engine of your Mercedes Vito, have a look at this article content for more informations.
The side effects of injector noise on Mercedes Vito
Now that we have analyzed the several reasons for injector noise on your Mercedes Vito, we will end by stating the possible consequences 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 side effects which can promptly 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 effects experienced 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 degrading one of your pistons or your engine. Poor combustion will promptly harm your cylinders or pistons and your engine may tighten.
Here are three little suggestions to limit the risks connected 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>
