Common Misconceptions About Diesel Generators

Over the years we’ve heard just about all there is to hear regarding diesel generators and generators on a whole. Some of the things we’ve heard are true and some aren’t so true, so with that said, we thought we’d take the time to clear up any confusion and put to bed any doubt in your mind.

They’re Not Very Reliable

People seem to think that diesel generators, whether hired or purchased, break down all the time. They splutter to start, need to be repaired all the time or come with faulty parts. Word of mouth has spread like wildfire to create an inaccurate rumor which paints generator suppliers, such as ourselves, in a bad light.

Any company that cares about its customers will always take the time to check all generators and parts to ensure they are fully functioning and ready to be used as a backup power source. The latest specifications should always be at the forefront (especially when hiring) and low mileage on the clock. If you have had a bad experience when hiring or purchasing a diesel-powered generator, it’s probably best to blame the company, not the generator!

They are Bad for the Environment

This might be a slightly outdated rumor, but every now and then it still pokes its ugly head up to say hello.

The latest diesel-powered generators are manufactured to be friendly to the environment, so that means cleaner emissions without the smelly, smoky attributes. They are predictable, economical and still deliver a reliable power output.

They’re Noisy

Modern diesel-powered generators can barely be heard and are extremely quiet. They won’t disrupt your workplace or have a negative effect on productivity, they will do what they need to do without the noise pollution associated with old diesel generators of old.

The best type of generator is the one that best suits your needs. As generator specialists, we can help you choose the best diesel generator to suit your needs. Whether it’s budget, types, brand or something else, then the Bellwood Rewinds team can help.
Why should I buy a new diesel generator over a used one?
There’s nothing wrong with used generators, and they're perfectly fine for a range of uses. However, new diesel generators will have a longer lifespan and are less likely to break down. The older a generator gets, the more likely it is to break down.
Should I buy an electric or diesel generator?
This is entirely down to you, and what your requirements are for a generators. At Bellwood Rewinds we offer a vast range of quality electric and diesel generators. One of our team can listen to your requirements and then advise on the best generator to purchase.
What Do I Need to Know About Buying a Diesel Generator?
The modern diesel generator is far more affordable, improved efficiency and the units are generally quieter this, in turn, raises the bar on power. Diesel generators are useful in homes, businesses, and factories as well as large functions such as wedding and corporate events. Purchasing of generators is based on the following factors: Power Output: The watts rated can be as low as 5kW which can supply power to multiple appliances. Generators of 30kW can supply power to medium sized home or business. Run Time: You can select which generator best suits your needs, depending on its run time. Price: The most important factor when purchasing a generator, many people prefer portable generators as they are the cheaper alternative, however, these generators can only supply small gadgets. Noise: Most generators now make less noise along with providing uninterrupted power. Most generators can be supplied along with an acoustic cover to further reduce noise pollution. Reliability: It goes without saying that reliability is an essential factor when purchasing a generator. Cheap generators with low quality will run efficiently, it’s important not to purchase a low standard generator just for the sake of saving money.
How does a diesel generator work?
A diesel generator works by turning mechanical power into electrical. The engine which is usually fuelled by diesel or gas rotates at a set number of rpm, most commonly 1500Rpm in larger generator sets. The rotational speed is fixed by means of a throttle stop keeping the engine at that fixed speed constantly. As the load increases or decreases on the generator, then the engine speed will increase or decrease, this is controlled by means of a governor which controls the amount of fuel to the engine, if the engine speed rises the governor will reduce the fuel it allows, and if the engine speed drops then it allows more fuel to the engine. The engine is connected to the part known as the alternator, this is the part that turns the engines mechanical power into the flow of electricity to the load. The alternator rotates at 1500Rpm and with the combination of copper windings and iron core packs it produces a voltage either three phase or single phase depending how it’s connected up. The voltage is kept stable by an Automatic Voltage Regulator or AVR for short. This device is set to keep the voltage stable for use with todays sensitive equipment. When the load increases the voltage will start to drop, the AVR allows more excitation to the winding thus increasing the output, when the load drops the voltage will start increasing so the AVR reduces the excitation. The AVR unit makes thousands of changes a second in order for the user to see a perfectly stable voltage. The generator as a whole is controlled by the generator control panel, this in modern generators is a digital device that starts and monitors all of the generator functions, such as: Engine oil pressure, coolant temperature, fuel pressure, output voltage, output frequency, current flow and many more. The control panel is set with pre-determined parameters via a laptop program, then if the machine exceeds any of these parameters the generator control panel will shut the machine down for investigation. Most generators are housed in an acoustic canopy that is lined with acoustic insulation to deaden noise, the canopy usually has a fuel tank in the base which will allow a minimum of 8 hours running time between fill ups, you can also get generators with much larger fuel tanks if required.
What is the best diesel generator?
The best diesel generators are ones that are built with the best quality components and to the highest standard. There is a massive number of generator manufacturers in the world but the best machines tend to be built with similar high quality components, below are some lists of what we consider the best quality manufacturers of parts: Engines: Perkins, Caterpillar, John Deere, Yanmar, Kubota, Doosan, Scania, Volvo…. Alternators: Stamford, Leroy Somer, Crompton Greaves, Meccalte, Marelli………..Control Panel: Deep Sea Controls, Comap……These lists are by no means exhaustive but an example of what would be considered as a good quality diesel generator.
What is a diesel generator set?
A diesel generator set is a machine that turns the rotary mechanical power from a diesel engine into a steady electrical power output supply from an alternator that is suitable to power anything from a computer to a full town.
How many hours will a diesel generator last?
There is no hard and fast rule of how long a diesel generator will last. It depends on size, usage and how well it is maintained. For example a 1000Kva diesel generator will outlast a 10Kva diesel generator by a high number of hours. This is due to the larger machine being far heavier built. Also the usage comes in to it, if you are running a diesel generator at 65% of its load capability it will last longer than if you are running it at 95%, it stands to reason, the higher the load the more strain is put on the engine and all of its components. As an example say a 60Kva diesel generator, which has a 500 hour service interval may well do 20,000 hours before needing a major engine overhaul if looked after properly along the way. The servicing and the quality of the fuel you fill it with is key to the lifespan of the machine. We regularly see machines around the 60-100Kva mark with in excess of 50,000 hours recorded on them if they have been properly looked after.

Top 3 Reasons to Choose a Diesel Generator

What you need to know about choosing a Diesel Generator

Purchasing a diesel generator is usually quite a heavy investment, so it’s important to make sure you know what you are choosing. Here we look at the reasons to choose a diesel generator and why.

Why choose a Diesel Generator?

It’s not worth spending more money than you need to on a generator that is too powerful for your needs. At the same time, you need to make sure the gen set you purchase is capable of restoring power in the event of an electricity outage.

When choosing a new gen set, specifically a diesel one, there are plenty of things that need to be considered. Here we look at the main reasons why you should choose a diesel generator, to help you with your buying decision.

Fuel can be stored on-site.

You can store fuel on site when you opt for a diesel generator. Although you can also purchase gas powered generators, you will need to connect your generator to the mains pipes in order for it to work.

Diesel is safe, reliable and cost friendly, making it a popular choice for when backup emergency power is needed. Mains pipes are not always available so diesel is quite often the preferred option.

Suited to your power needs.

When purchasing a new diesel gen set, you need to consider your power needs to make sure you get your hands on the best engine to suit your requirements. Diesel generators are manufactured to cater for various power needs, with a range of models available to suit.

With any diesel generator, not just diesel, it’s important for you to consider your capacity requirements. This is the max total load you’ll need your generator to cope with at any given point, should the power go down. By adding up all the electrical loads of the systems, you can calculate the total amount of power you’ll need to cover.

The generator you select must be able to handle this potential load, taking future power needs into consideration too. If you electricity requirements will grow, it’s wise to factor this in when purchasing a new diesel gen set. Bare in mind that running a diesel generator under its rated load by a large amount can cause damage to the system and reduce reliability.

Perfect for a range of environments.

Diesel generators are perfect for use in a range of environments and applications. They can be tailored to suit your place of work or home, should you wish to have a backup power source for your house.

Gen sets can be enhanced with extra features, such as custom containers and enclosures for protection. Enclosures can be tailored to suit the gen set in question.

For example, you might want a weather louvre to protect the supply and exhaust ducts from the harsh elements outside. You might also want noise-reducing doors, depending on your location and environment, to keep noise levels to a minimum. These are just a couple of the custom features that can be added to your diesel generator enclosure, no matter where you are based.

How Do Diesel Generators Work?

If you’re not familiar with diesel generators you may be wondering what they are and how they work. A diesel generator is the combination of a diesel engine and an alternator or electric generator which is used to generate electrical energy. The alternator is the generator which generates the electrical power, whereas the engine is used to rotate the electrical generator, however diesel generators are mostly used as an emergency power supply.

The Working Principle

Diesel generators work in four cycles:

  • Suction/ Intake
  • Compression
  • Power
  • Exhaust

The working principle of a diesel generator is based on the law of Energy conversion i.e. “Energy can neither be created nor be destroyed but be only converted from one form to another form.” Diesel has a chemical energy, during combustion the chemical energy is converted into heat and force. This force is known as mechanical energy which helps in rotating the alternator. The combustion is processed by a spontaneous ignition of the fuel when injected into a highly compressed charge of air which has reached around 750 degrees Celsius.

Suction Stroke

The piston moves from the centre due to the inlet valve opening, the air is then drawn into the cylinder. When enough air is drawn with pressure the suction valve gets closed at the end of the stroke.

Power Stroke

Fuel is inserted into the hot compressed air, it starts burning and then maintains the pressure, when the piston reaches the top centre the supply of fuel turns off. The injection of the fuel at the end of the compression stroke continues until the cut off point. The inlet and the exhaust valve remain closed and the hot gases and compressed air now expand in the cylinder which causes the piston to move down until it reaches the bottom dead centre.

Exhaust Stroke

During this stroke, the piston again moves up and allows the exhaust valve opens forcing the inlet and fuel valve to become closed. The burnt fuel gases escape due to their own expansion, the remaining gases are pushed out by the upward movement of the piston through the exhaust valve. When it comes to the end of this stroke, the exhaust valve closes, and the cycle is completed.
