It is never pleasurable to listen an injector noise on your Toyota Land Cruiser Serie 70. It is a noise that comes up regularly, usually when you accelerate or your engine is idling. However, this warning sign may be connected to several kind of problems with your vehicle injectors. It may not be anything major, but when a recurrent noise shows up, you have to be sure. Specifically since replacing your Toyota Land Cruiser Serie 70’s injectors can be costly. That’s why our team decided to produce this article in order to support you see more clearly, learn about the different possible failures and determine your problem. To do this, we will first look at the normal running and usefulness of the injectors in your Toyota Land Cruiser Serie 70, then at the possible reasons from which an injector noise may come.
Attributes of the injectors
Injectors are a very fundamental part of the operation of your engine motor. They were introduced to the modern cars 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 possibility, 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 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 caused by the injectors of your Toyota Land Cruiser Serie 70
Discovering injector noises on your Toyota Land Cruiser Serie 70 may come from different sources, 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 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 advise you to browse this article about clicking noise on Toyota Land Cruiser Serie 70 to discover the reason.
The reasons for injector clicking or knocking noise Toyota Land Cruiser Serie 70
A clicking or knocking noise from your injectors can be explained for different reasons. Indeed, the injectors of your Toyota Land Cruiser Serie 70 have three main tasks, to control the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to facilitate its combustion. Then, its objective 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 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 as a consequence of bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will trigger thoses knocking or clicking noises on your Toyota Land Cruiser Serie 70. 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 obstruction will inevitably lead to a malfunction of the injector. If after verifying, this noise originates from another component of the engine of your Toyota Land Cruiser Serie 70, read this article for more infos.
The end result of injector noise on Toyota Land Cruiser Serie 70
Now that we have reviewed the different causes for injector noise on your Toyota Land Cruiser Serie 70, 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 repercussions 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 repercussions experienced by drivers is a severe loss of power. Indeed, if your engine is running on 3 out of 4 cylinders for example, you will surely have a loss of power
Finally, you risk deteriorating 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 swapping your diesel fuel filter regularly>
