Benefits Of Diesel Generators

  • Safer
  • Low Noise
  • Cost Effective
  • Less Maintenance
  • Longer Lasting
  • Reliable

Diesel Generators are Safer

No Sparks!
  • Unlike gas engines, diesels have no spark plugs to replace, or carburetors to service.
  • Diesel is not explosive like gasoline, propane, and LP gas.

Safer to Store!

  • It’s safer to store because diesel does not explode like gasoline, natural gas or propane.

Safer Exhaust Fumes!

  • A well-tuned diesel produces no visible exhaust except briefly, under severe load-changes.
  • Exhaust is less toxic than the emissions from a gasoline engine.


Diesel Generators are Cost Effective -Lower fuel costs

Less Expensive

  • Diesels generally burn less than half the fuel compared to gas engines used to complete the same amount of work.
  • Diesel fuel is less expensive compared to gasoline or propane. It requires a shorter refining process.
  • Fuel cost per kilowatt (KW) produced is 30 to 50 percent lower than gas burning engines

More Efficient

  • Diesel requires less fuel consumption per kilowatt (kW) produced) because diesel enjoys a superior energy density.
  • This means you can have more energy compared with the same volume of gasoline or propane.
  • A diesel engine allows the air and the fuel to be infused into the engine at different stages, as opposed to a gas engine whereby a mixture of air and gas are introduced at the same time.

Higher Compression Less Fuel Usage

  • Fuel is injected into the diesel engine using an injector instead of a carburetor.
  • In a gasoline engine, fuel and air are sent into the engine together and then compressed. This kind of mixture limits fuel compression and reduces the overall efficiency.
  • A diesel engine compresses just air, and the proportion can be much higher.
  • A diesel engine compresses at the ratio of 14:1 up to 25:1.
  • A gasoline engine compression ratio is between 8:1 and 12:1.


Diesel Generators Require Less maintenance

Easier to Maintain

  • Diesel engines have fewer parts. No spark system.
  • It’s heavier and oilier compared to gasoline.
  • Diesel is more rugged and a more reliable engine.

Lower Maintenance Costs

  • Overall operating costs are normally 30% to 50% less than gasoline units. 
  • Diesel engines running at 1800 RPM and water cooled operate on average for 12,000 to 30,000 hours before major maintenance is required.  Gasoline engines running at 1800 RPM and water cooled gas units usually operate on average for 6,000 to10,000 hours because they are built with lighter duty gasoline engine blocks. 

Tune-Ups Only!

  • Gasoline units run hotter due to the higher BTU rating of the fuel.
  • Because of this higher BTR rating, owners will experience a significantly shorter gasoline engine life.
  • Diesel engines run cooler and last longer.


Diesel Generators are Longer Lasting

Long Lasting --- Diesel Generators are more rugged and reliable. Consider the 18 wheeler trucks capable of 1,000,000 miles of operation before major service. Most trucks are diesel powered.

  • The only maintenance generally required is changing the oil, and changing the fuel, air and oil filters. (This is the same as a gas engine.)
  • Gas units burn hotter than diesel units, and hence they have a significantly shorter life compared with diesel units.
  • No sparking as the fuel auto-ignites. The nonexistence of spark plugs or spark wires decreases maintenance costs. 

Simple Maintenance

  • If you know how to care for a gas engine, you can service a diesel.
  • A diesel 1800 rpm water cooled unit operates for 12,000 to 30,000 hours before major maintenance is required.
  • No carburetor adjustments, no distributor or magneto to burn out, and no spark plugs to need periodic cleaning and replacement.
  • Oil changes done on schedule are critical and make the difference between an engine that wears out prematurely and one that runs long term.

Diesel Generators are More Reliable

  • The generator features a brushless design and automatic voltage regulation for reliable power.
  • The generating set is designed to run continuously or as a back up power supply so you can have confidence for short term and long term power outages that may last weeks..  
  • Diesels are simpler in design and construction than gas engines so they are easier to maintain and have less opportunities for failure.
