Diesel is the best fuel for a standby generator.

You have probably recognised that most standby generators are diesel powered rather than petrol (gasoline) or LPG.

diesel is the best fuel for power gen setsIt isn’t just accident. Diesel fuel has some inherent advantages that make it very suitable for power generation duties in a wide variety of applications and environments.

So what are the key reasons why diesel is the fuel of choice in the power generation sector?

  • Diesel generators consume fuel at roughly half the rate of petrol engined equivalents. Even in the UK where diesel is usually more expensive than petrol, diesel generators are cheaper to run.
  • The compression ratio for diesel engines is between 14:1 to as high as 25:1, which means that they run more efficiently than petrol engines that run at between 8:1 to 12:1.
  • Diesel is a safer fuel to use and store.  It has a higher flashpoint than petrol which means it is more difficult to ignite. The generator engine compresses the fuel, which heats it up to combustion temperature.In case you are wondering, glow plugs are there for when an engine is cold and heat gets dissipated away from the cylinder walls.
  • The ignition and lubrication characteristics of diesel make engines more reliable and long-lasting.  So both maintenance costs and longevity are better than with petrol-engined generators.

No wonder that so many people are taking advantage of Eagle Generator’s excellent choice of new and used diesel generators.  We can offer some great deals on brands such as Cat, Cummins, FG Wilson, MTU and Perkins.
