Taking a Look at Electronic Fuel Injected Engines (EFI)

Why Choose an EFI Engine Lawn Mower?

About three decades ago, the automobile industry went through a nationwide revolution!  Between rising gas prices and pressure to become environmentally friendly, automobile manufacturers made the switch from traditional, carbureted engines to Electronic Fuel Injected Engines.  Following the success of EFI Engines in the automobile industry, most commercial mowers and landscapers were also looking for an EFI Alternative in their lawn mowers, which led to a nationwide boom in Electronic Fuel Injected Lawn Mowers.  If you’re still running on a carbureted engine, here are some reasons why switching over to EFI engines could be huge for you and your mowing operation!

How Does EFI Work?

Fuel injectors are electronic valves that send a fine mist of fuel to each cylinder.  Each valve is connected to a computer that calculates factors, such as:

  • Temperature
  • Air Density
  • Throttle Position
  • Air Intake VolumeInjector3

The EFI Engine’s computer takes real time readings of each of these factors, then uses these readings to adjust the amount of fuel that is being injected into the cylinders.  Because of the flexibilty, EFI engines perform better and consume less fuel than carbureted engines.

Environmentally Friendly

EFI Equipped mowers use less fuel, give off less CO2, and offer a cleaner burn than traditional engines.  Studies have shown that EFI engines use between 25 and 30% less fuel, which greatly reduces it’s carbon footprint!  EFI engines are also more flexible and versatile than the bulky design of the traditional carburetor.

Cost Effective

Along with being incredibly environmentally friendly, EFI engines will also save you a lot of money!  EFI engines use 25% less fuel, which means you will save 25% on fuel costs!  Is that not impressive enough?  Let’s put that into real-world terms.

Let’s pretend that you own a commercial mowing business.  You run your carbureted lawn mower 600 hours per year, and your lawn mower consumes 1.35 gallons of fuel per hour.  If gas prices are $3.50, then at the end of the year, you will pay $2835 in fuel costs alone.  But when you switch to an EFI engine, your fuel consumption will be reduced to 1.01 Gallons per hour, and your annual fuel cost will be reduced to $2121!  With an Electronic Fuel Injected Engine, you will save around $714 per year, and that’s only for one mower!  If you replace four of your mowers with EFI mowers, you will save over $2800 per year on fuel costs!  If that’s not enough to make the switch, I don’t know what is!
