Diesel Electric Generator Efficiency

While grid power remains the primary source for most, its reliability can be compromised during outages or emergencies. Diesel generators step in to fill this gap, providing a reliable and independent source of power when needed most.

These generators, powered by diesel engines, offer a robust and versatile solution for maintaining essential electrical services during unforeseen interruptions. No matter the setting, diesel generators stand ready to provide prime power or backup power, ensuring that operations can continue uninterrupted even when grid power is unavailable.

How Diesel Generators Work

Diesel generators have a history spanning over a century, operating uniquely compared to other engine fuel variants due to their internal combustion diesel engine.

The diesel engine’s configuration combines unit injectors to introduce compressed air (carbon dioxide) and diesel fuel into a combustion chamber.

This process initiates heat production to ignite the fuel, with a higher compression ratio resulting in reduced diesel consumption, enabling a slower fuel burn rate and greater fuel efficiency.

This sequence kickstarts the generator, where the internal combustion engine transforms the chemical energy present in diesel into mechanical energy, then converting it into electrical power.

Thanks to the efficiency of diesel generators, they are a favoured choice for prime power or continuous operation where grid power or natural gas connections are unfeasible, such as in construction sites or events.

Diesel Generator Operation

Diesel generators rank among the most efficient options available in the generator market. However, the specific requirements you have for a generator will dictate the most suitable option for your needs. Running a generator can incur significant expenses, particularly during prolonged usage. In the UK, the expense of operating a generator is based on various factors, including the fuel type, generator size, and frequency of use.

The larger the generator the more fuel it will consume, so this is important to keep in mind when choosing the size of the generator.

Operating a generator for prolonged periods can result in several issues:

Fuel Consumption: The longer the generator runs, the more fuel it utilises, thus escalating operational expenses.

Increased wear and tear: Continuous operation can cause heightened strain on the engine and other components, necessitating more frequent maintenance and repairs.

Safety concerns: Generators emit carbon monoxide, an odourless gas that can be fatal in concentrated levels. If running the generator for extended durations, proper ventilation is essential to prevent carbon monoxide accumulation.

Generally, it’s advisable to only run the generator when necessary. During power outages, it can be turned on temporarily until the main power is restored. Once power returns, switching off the generator helps mitigate unnecessary wear and conserve fuel.

However, certain circumstances may demand extended generator operation, such as during prolonged outages. In such cases, ensuring safe and efficient operation involves a few factors.

Regular maintenance, and consistent upkeep including oil changes, air filter replacements, and spark plug checks, is vital for smooth generator operation. Opting for high-quality fuel can prevent engine buildup, enhancing performance and reducing fuel consumption. Given the carbon monoxide risk, proper ventilation is important to prevent its dangerous accumulation in enclosed spaces.
