Kohler Engines Releases Closed-Loop EFI Propane Engine

Kohler Propane Engine 

Kohler® Engines released in October a new engine that combines the company’s closed-loop EFI (electronic fuel injection) technology with the benefits of propane. The Kohler Command PRO® EFI Propane Engine is a highly efficient, environmentally-friendly option, akin to the gasoline version, that provides increased productivity and low overall operating cost to landscape contractors and other green industry professionals. The new propane engine is offered on Kohler’s 23 and 27 horsepower Command PRO® EFI commercial line.

“We’re the only manufacturer to offer a propane-fueled EFI engine,” said Mark Johansen, senior product manager for Kohler Engines. “This is a pretty significant combination. After all, green industry pros now have access to the clean-burning, eco-friendly benefits of propane in tandem with the incredible efficiency and proven performance of our closed-loop EFI technology.  It’s an ideal option for those looking to add to their eco-friendly fleet as well as those who have been waiting to jump into propane technology.”

Many landscape contractors nationwide have turned to propane to ensure they can stay up-and-running during “Green Days” or “No-Zone Days,” when local municipalities prohibit the use of gasoline-powered equipment.

When paired with Kohler’s exclusive closed-loop EFI technology, utilizing a propane engine makes even greater sense. Kohler EFI engines integrate an oxygen sensor that analyzes the air/fuel mixture in the unit’s muffler. If the oxygen level strays from the ideal mixture, the sensor triggers adjustments to the amount of fuel injected into the system. Kohler’s EFI technology then “close the loop” between the air/fuel intake and the exhaust output to provide a constant stream of critical feedback, which helps deliver optimal fuel efficiency and a variety of other benefits, including easy starting, improved power and increased life span.  

Together Kohler Engines and Lombardini, a KOHLER Company, represent a global engine concern manufacturing engines since the 1920s. Kohler Engines produces a wide range of gaseous, gasoline and diesel engines, from 4 to 74.3 hp, which are supplied to equipment manufacturers worldwide in the lawn and garden, commercial and industrial, agricultural and construction markets.
