A diesel generator isn’t only a great investment but it’s also an excellent
asset. However, due to the fact that it is a machine, it is bound to have some problems later on. Some of these problems can be avoided by doing regular maintenance, but some are unavoidable.
Nonetheless, in case your diesel generator starts “acting out”, you should always have a solution at hand. Click here to check out this champion generator on Amazon.
To help you out, below we have compiled the most common diesel generator problems and solutions.
This knowledge will be very helpful if your diesel generator does have a problem and it will also prepare you for any issue that may arise.
Failure to Start
Let’s start with the most common problem. Does your diesel generator fail to automatically start?
There are a couple of reasons that could cause such a problem. The most common one is that you have not set the controls to auto.
You can go back to your manual and check out how to set the generator to start when needed.
Wet stacking can be defined as the build-up of unburned fuel in the exhaust system. Also, wet stacking can be caused by long periods of running under a light load.
As a result, forcing the engine to perform under the required temperatures. Signs of wet stacking entail a presence of bluish oil. If you also notice that the lubricating oil is being over-consumed, that could also signal wet stacking.
To avoid wet stacking, it is advisable that you run your diesel generator with an at least ¾ load. This will enable it to reach the required temperature and thus completely burn fuel.
Burning of Excess Fuel
This is one diesel generator problem that can really create a big dent in your pockets.
A generator burning more than the required fuel is a problem that needs to be dealt with as soon as possible. But how do you know your generator is burning excess fuel? Black sooty smoke is an indication.
This can occur if the injector tips are worn out. A worn out injector tip is responsible for fuel into the cylinder even when the generator is idle. To solve this problem, you will need to replace the worn out injector tips.
Leaking is also another common generator problem. There are three common types of leaks; fuel, coolant and lubricating oil.
Each of these leaks can have very adverse effects on the performance of your diesel generator.
Leaks are bound to happen due to an increase in temperatures, and wet stacking amongst other things. To avoid leaking, maintenance should be done on the regular.
For instance, all hoses should be replaced after two years. You can do the replacement earlier than the stipulated period depending on how frequent the generator is used.
It’s why it’s advisable for you to adopt a regular routine maintenance check.
Additionally, gasket failures can also lead to leaking. At times, leaking may occur and you may not about it because of a malfunctioning fuel gauge.
These gauges may become stuck and as a result, catch you off-guard. It’s best if you manually check the fuel levels.
There are some diesel generators that become hot when used for an extended period. However, if you notice an abnormal rise in temperatures, then you need to do something about it.
Overheating is often a result of low coolant levels. You, therefore, need to check that out. If the coolant is in low amounts, then a refill is in order.
Additionally, you should always check the coolant, lubricant and fuel levels before starting your generator.
Most people only check the fuel levels not knowing that the other two are equally important for the proper functioning of the diesel generator. The low coolant levels can mostly be caused by leakages.
High Fuel Level Alarms
Do your high fuel level alarms go off frequently? Might worried something to be wrong? Well, you shouldn’t be.
A high fuel level alarm is a standard protocol that is installed in most generators with the aim to notify that the tank is almost full.
The alarm activates when the fuel tank levels exceed 95%. However, in some cases, due to an increase in temperature.
The alarm may activate due to the expansion of the fuel. This can also happen on hot sunny days. You can either switch the alarm off or reset it manually.
How to Reduce Noise in a Diesel Generator
Diesel generator noise reduction Tips
Diesel generators are more fuel-efficient and require less maintenance than their gasoline counterparts.
Nonetheless, most people shy away from diesel generators due to the worry that they may be too noisy. Thankfully, below are a few effective techniques for making your diesel generator quieter.
Using Anti-Vibration Mounts (AVM)
Reducing the generator’s vibrations goes a long way in decreasing its noise levels. This can be achieved by installing anti-vibration mounts under the generator.
Common types of AVMs include dampers, as well as rubber and spring mounts.
Acoustic Barriers and Insulation
Sound barriers denote solid surfaces that restrict the transmission of noise to external areas by reflecting the waves.
For instance, concrete walls and standard generator canopies go a long way in reducing the noise levels by about 10dB.
An even better noise reduction method involves installing sound-absorbing materials like acoustic wall tiles or panels inside the generator enclosure.
Sound Attenuation Housing
Among the most effective method of reducing noise levels from a large industrial generator entails the use of attenuators.
An attenuator is a large enclosure built of steel. It features perforated sheet metal with high-density rock wall infill known as a splitter, which comes in handy in absorbing sound and reducing wavelength.
Attenuators can be custom built depending on the size of your generator.
Increasing the Distance
The easiest way to reduce noise from a diesel generator is to increase the distance between your house and the equipment.
Moving the generator away from the house allows the wavelengths to disperse at a greater distance, which decreases the acoustic intensity, reducing the noise significantly.
Diesel generators can be quite noisy, especially in quiet neighborhoods. However, this shouldn’t be an excuse for refraining from investing in one.
By the use of anti-vibration mounts, acoustic barriers, sound insulation, and attenuators, you can bring the noise of your generator to bearable levels.
You may also have the generator installed in a far off corner of your home.
How To Repair A Troubleshoot In Your Generator
A generator can be a complicated and complex machine, especially if you don’t know the overall functions of the parts and how to fix it when something goes wrong.
However, it doesn’t have to go downhill from there.
The following is a list of problems that could potentially go wrong in a generator and how to reach each issue:
Fuel problems Oil problemsYour generator failing to start
When your generator has problems with its fuel, Storing fuel in your generator for lengthy periods of time can lead to a malfunction in your generator.
It’s important to replace the used fuel with fresh fuel to avoid fuel problems in the future.
When your generator has problems with its oil, it’s usually due to a low level content of oil.
This can cause a long-term damage to the generator and prevents it from running in the first place. Be sure to always check the oil level of your generator.
When your generator fails to start, it’s usually always due to a loss of residue magnetism which is caused when you haven’t used your generator for a long period of time.
How to troubleshoot a diesel generator (Step by step)
Diesel generators could really give peace of mind and give you the capability to use your refrigerator and some other essential appliances; even the power is out.
Because the diesel generator is a significant piece of hardware, it’s vital to maintain and care for it appropriately.
It’s also essential to realize what steps on troubleshooting to take when your diesel generator operates inadequately or would not start.
Attempt to turn on the power diesel generator. If the diesel generator would not start, one reason is that the fuel is degraded.
Diesel generators are utilized occasionally; that means they’re unused yet loaded up with gas or fuel.
That fuel would start to deteriorate after some time. At the appropriate time, the fuel quality will end up being a low quality that the unit would not start.
Void the fuel tank and put the diesel generator with new fuel. Attempt to control on the unit again. If the power diesel generator still would not start, the issue can be a tarnished or stopped up air channel.
Take a gander at the spark fitting condition. A very much utilized, chaotic or fouled spark fitting could reduce the operation of your diesel generator.
Various models of the diesel generators were very disposed to flooding. If your diesel generator isn’t appropriately starting, you should take a gander at the spark plug for the unburned fuel nearness.
Carefully detach the front of the spark plug and disconnect the spark plug.
Take a gander at it for indications of damage and wear, at that point clean and change the attachment. If the spark attachment is damaged or fouled, change it with another one.
Keep several extra spark plugs with the goal that you’ll always have one as a replacement.
The above are six diesel generator problems and solutions on how to tackle them. A diesel generator as mentioned earlier is useful machinery.
In case of an outage, it is a reliable source of power. A malfunctioning generator can interfere with your daily operations it’s why you should familiarize yourself with these problems and how to solve them. Champion 3400 is a great generator that you can check here.
