Yes, diesel generators are considered better than petrol generators for a number of reasons.

Diesel fuel is denser than petrol and has about 15% more energy per volume, which results in higher thermodynamic efficiency and less fuel consumption. Diesel engines also produce combustion by injecting fuel into the cylinder and compressing the air, making them less prone to engine knocking issues.

Additionally, diesel engines are considered more robust and hardy, as they are built to withstand the high compression and temperature required for combustion. Diesel fuel is also more stable and less prone to accidental ignition, and the fuel system is self-lubricating. Finally, diesel engines produce more torque at low RPMs compared to petrol engines.

Diesel generators are known for their high efficiency compared to petrol generators. The high thermodynamic efficiency of diesel fuel, which is denser and has about 15% more energy per volume than petrol, results in less fuel needed to produce the same amount of power, and thus, less emissions.

The efficiency of a petrol engine is around 20%, meaning only 20% of the burnt fuel is used to move the engine, while the efficiency of a diesel engine is around 40%. Most of the fuel is lost to friction, noise, heat, and other engine functions in petrol engines, while diesel engines are able to retain more of the energy from the fuel for use in producing power.

This means that even though diesel fuel may sometimes be more expensive per litre than petrol, the fact that you need less fuel in a diesel engine could make it a cost-effective solution in the long run.

The continuous run time of a diesel generator depends on several factors such as the size of the generator, fuel capacity, load demand, and maintenance. As a general rule, larger generators with larger fuel tanks and regular maintenance can run for longer periods of time.

On average, diesel generators can run continuously for anywhere between 8 to 72 hours depending on the generator's specifications and the load demand. It is recommended to consult the manufacturer's specifications and seek professional advice to determine the appropriate continuous run time for your specific generator and application.

The lifespan of a diesel generator depends on various factors such as usage, maintenance, and environmental conditions. On average, a well-maintained diesel generator can last anywhere from 10,000 to 50,000 hours of operation. However, some diesel generators can last longer if proper maintenance and usage practices are followed.

It is important to perform regular maintenance and inspections on your diesel generator to ensure it operates efficiently and lasts as long as possible.

The cost of a diesel generator can vary greatly depending on its size, power output, brand, and features. Small portable diesel generators can cost anywhere from a few hundred dollars to a few thousand dollars.

On the other hand, larger industrial diesel generators can cost tens of thousands of dollars or more. The cost of a diesel generator also depends on the region, local market conditions, and any additional equipment or services that may be required for installation and maintenance. It is important to consult with a generator expert to determine the most appropriate and cost-effective solution for your specific needs.

The amount of fuel a diesel generator uses depends on several factors, including its size, power output, and operating conditions. The fuel consumption of a diesel generator is typically measured in gallons per hour (GPH) or litres per hour (LPH).

A small portable diesel generator may use only a few litres per hour, while a large industrial generator may consume several hundred litres per hour. The efficiency of the generator also plays a role in fuel consumption, as more efficient generators will use less fuel to produce the same amount of power.

Additionally, the load being placed on the generator will also impact fuel consumption, as a generator running at full capacity will use more fuel than one operating at a lighter load.

The noise level of a diesel generator can vary depending on several factors, including the size of the generator, the type of enclosure or canopy it is housed in, and the manufacturer's specifications. Generally, diesel generators can produce a substantial amount of noise, especially when they are running at full capacity. This can be a major concern for homeowners who want to use a generator as a backup power source and businesses that want to avoid disturbing neighbours or customers.

To mitigate the noise produced by a diesel generator, many manufacturers offer acoustic enclosures or canopies that can significantly reduce the noise level. These enclosures are designed to dampen the sound waves generated by the generator, so that the noise level is much lower. Some of these enclosures can reduce the noise level to as low as 60 decibels, which is about the same level of noise as a normal conversation.

When considering a diesel generator, it is important to look for one that is designed to produce as little noise as possible, or one that can be housed in an acoustic enclosure or canopy. You should also consider the location of the generator, and make sure that it is installed in a place where the noise level will not be a problem. 

With Welling & Crossley, you can have peace of mind knowing you are getting a reliable and low-noise diesel generator that meets your specific needs.

A backup generator is essential for both individuals and businesses in case of a power outage. A diesel generator is a popular option due to its efficiency, reliability, and cost-effectiveness. However, it's important to know what kind of fuel storage is needed for your diesel generator to ensure its proper operation.

The simple answer is yes; diesel generators do require special fuel storage. Diesel fuel is flammable and must be stored safely and securely to avoid accidents or spills. Here are a few important things to consider when it comes to diesel fuel storage for your generator:

  1. Fuel Type: It's important to use only diesel fuel in your generator, as using other types of fuel can damage the engine.
  2. Container Material: The container used for diesel fuel storage should be made of a material that is compatible with diesel fuel, such as steel or high-density polyethylene (HDPE).
  3. Storage Capacity: The size of the fuel storage container should be appropriate for the generator's fuel consumption and the length of time it is expected to run.
  4. Ventilation: Proper ventilation must be provided in the storage area to prevent the build-up of fumes and ensure the safety of those working around it.
  5. Location: The fuel storage container should be placed in a secure area, away from heat sources and other potential hazards.
  6. Compliance with Regulations: The storage of diesel fuel must be in compliance with all local, state, and federal regulations, including fire codes and environmental regulations.
