Best Portable Diesel Generator For Sale

Here we’ll take a look at the benefits of diesel generators and the best portable diesel generator for sale at the mid and large sizes.

Diesel Generators CTADid you know that in 1936 Mercedez-Benz built the first diesel engine powered car?

What about that diesel engines release 25% less carbon monoxide than comparable gas engines?

They’re pretty impressive.

Invented in 1892 by Rudolf Diesel to replace steam and other combustion engines, diesel engines quickly found work in the shipping industry.

Today they are used in a ton of applications – here’s just a few:

  • Aircraft
  • Motorcycles
  • Trains
  • Tractors
  • Pumps
  • Trucks
  • Cars
  • Buses
  • Construction equipment
  • Submarines
  • Industrial equipment
  • Generators

So what’s all the fuss about diesel engines?

What Are The Advantages of Diesel Engines?

  1. Diesel fuel has 14% more energy per volume than gasoline.
  2. Diesel engines are about 45% efficient at turning the chemical energy of the fuel into mechanical energy. Gasoline engines are 30%.
  3. Diesel fuel is a better natural lubricator.
  4. Diesel engine’s performance peaks at lower RPMs lengthening the engine life and the time between maintenance.
  5. Diesel engines are designed stronger, thicker and more robust to withstand compression reaction within the combustion chamber (compared to gas engines which use spark ignition).
  6. Diesel fuel is the least flammable of all fuel types used in generators.
  7. Although not a guarantee diesel fuel is probably easier to obtain than gasoline since tanks and other more industrial and military vehicles need diesel during a natural disaster.
  8. Because diesel engines use a compression reaction they have no spark plugs to replace. That means they also have no wires or electric system in the engine area increasing reliability in damp environments.

Disadvantages?

  1. Louder than gas engine due to the more forceful explosion in the combustion chamber.
  2. Diesel fuel can’t be stored long. At least compared to natural gas.
  3. Repairs to the diesel engine may be more expensive since a Diesel Mechanic might charge more.

What’s The Deal With Diesel Generators? Are They Better Than Gas?

Diesel generators have a ton of pros over gas, propane and natural gas. One of those pros is not price. Diesel gensets are more expensive for the same size. You’re looking at nearly $3500 for a 5000 Watt diesel generator. You can get the same size gas generator for $700.

Diesel generators are most popular in permanent use situations. This is because they last longer and handle consistent load easier.

These days it’s hard to find a diesel generator. Why? Because the businesses that make and sell them realized people didn’t want to pay the extra money to get diesel. And the company’s couldn’t give them away so they just switched focus to what people want. Affordable generator. The only solution for the businesses to stay in business is gas generators.

Despite there being few portable personal-use diesel generators, there are a few. And this is the best:
