Kohler Engines. Relentless Power. Legendary Performance.

Command PRO EFI Propane

PCH680

PCH680

Ditch that inefficient propane engine conversion. And say hello to a cleaner burning, more fuel-efficient EFI propane engine that saves you up to $1200 a year on fuel (Compared to a comparable Kohler carbureted gasoline engine under comparable loads and duty cycles and based on a gasoline price of $3.65/gal and a propane price of $1.75/gal and 600 hours of annual operation).
Our exclusive Command PRO® EFI engine with closed-loop electronic fuel injection now offers a propane option designed for higher performance using less fuel. It saves you cash hour after hour, year after year.

Overview

Professional Grade Design.

Closed-loop electronic fuel injection is just one of the pro features you get. With no carburetor, there are no carburetor problems and no fuel stabilizer needed. These engines automatically adjust to load, weather and altitude for better performance and are backed by a 3-year unlimited-hour commercial limited warranty.

Reliable Starting.

These engines start like your car - just turn the key and go. There's no choking, no priming and no fuel pressure adjustment. Plus, there's no carburetor maintenance and less downtime.

Increased Efficiency.

KOHLER EFI propane engines produce over 50% fewer hydrocarbon emissions than a typical carbureted engine, helping to reduce smog formation (compared to a comparable Kohler carbureted gasoline engine under comparable loads and duty cycles). They may be used on Ozone Action Days and can help you win “green” contracts. Plus, 25% less fuel means 25% less carbon-based greenhouse gas emissions. They also reduce carbon monoxide (CO) emissions by up to 50%.

User-Friendly.

EFI diagnostic software provides a quick diagnosis to help detect and fix problems if they occur.

High Power Performance.

Command PRO EFI automatically optimizes for fuel grade, fuel quality and altitude.

Electronic Fuel Injection.

Save up to $1200/year when you run an EFI propane engine 600/hours a year. Save up to $2.00/hour compared to a carbureted gasoline engine. And save up to $1.25/hour compared to a carbureted gasoline-to-propane engine conversion (compared to a comparable Kohler carbureted gasoline engine under comparable loads and duty cycles; based on a gasoline price of $3.65/gal. and a propane price of $1.75/gal. and 600 hours of annual operation).

1 Power (hp) and Torque (lbs ft) specifications for Kohler general purpose engines are rated pursuant to Society of Automotive Engineers (SAE) J1940 based on gross output testing performed according to SAE J1995 without the air cleaner and muffler. Actual engine power and torque are lower and affected by accessories (air cleaner, exhaust, charging, cooling, fuel pump, etc.), application, engine speed, ambient operating conditions (temperature, humidity and altitude) and other factors. This J1940 / J1995 rating provides consistent measurement to customers who may want to control the intake and exhaust features of the engine. For more information, contact Kohler Co.
