Why EFI? A Look at the Benefits of Electronic Fuel Injection

 February 3, 2016

In addition to traditional carbureted engines, most Exmark commercial zero-turn, stand-on and walk-behind mowers are also available with engines equipped with Electronic Fuel Injection (EFI). Today, we’ll discuss EFI’s benefits and why you might want to consider equipping your next mower with a fuel-injected engine.

Exmark offers state of the art EFI-propane engines on its commercial zero-turn, walk-behind and stand-on riding mowers.

What is EFI?

EFI replaces the carburetor as the mechanism responsible for mixing fuel and air, and delivering the mixture to the engine cylinders, so it can be burned, and power can be produced.

Unlike a carburetor, which relies on the vacuum created by the engine to work, a fuel-injected engine uses pressurized injectors to spray a precisely-metered amount of fuel into the air stream as it enters the engine. The system’s ability to adjust the fuel/air mixture based on altitude and environment is a major benefit for commercial mower users on a number of levels.

Electronic Fuel Injection reduces fuel consumption, downtime and maintenance costs, while it increases power, performance and ease-of-starting.

EFI Benefits

  • Productivity — EFI optimizes the fuel/air mixture to deliver maximum power and responsiveness at any altitude, in any weather. You’ll get more work done thanks to the optimized performance.
  • Fuel economy — Save up to 25 percent or more on fuel costs compared to similarly equipped carbureted mowers. For a landscape professional, this can amount to hundreds of dollars of fuel savings per year for each machine.
  • Easy starting — With no choke, you’ll get quick starts every time, hot or cold.
  • Reduced service/downtime — With no carburetor, fuel injected engines have no carburetor-related maintenance costs or downtime.

Exmark EFI-Equipped Mowers

Exmark offers Electronically Fuel Injected engines across its line of commercial mowers, including Lazer Z (zero-turn rider), Navigator (dedicated bagging rider), Vantage (stand-on rider) and Turf Tracer (walk-behind) models.
