Kohler has added 12 Command Pro EFI (electronic fuel injection ) engines ranging from 19 to 29 hp (14 to 21 kW) to its line. Beginning with the Command Pro 747 cc, the company will convert all Command Pro engines to closed-loop EFI. Previously using EFI as an option on select air- and liquid-cooled models, Kohler now partners with Delphi for an integrated EFI system that offers improved fuel savings and performance with reduced emissions among multiple power levels. The standard closed-loop systems include an oxygen sensor to analyze the air/fuel mixture in the exhaust and possibly trigger the ECU map to adjust the amount of fuel injected into the system, closing the loop between the air/fuel intake and the exhaust output. Benefits include optimized power and fuel economy, automatic adaption to operating conditions, instant load response, and use of the same footprint to prevent end equipment alteration.
