www.outdoorpowerequipment.com OUTDOOR POWER EQUIPMENT OCTOBER 2014 41 Products Product NEws Most advanced EFI technology Like all the Kohler EFI engines, the 824-cc Command PRO EFI uses the Kohler- designed closed-loop system, which means an oxygen sensor in the muffler continuously analyzes the air/fuel mixture. If the air/fuel mixture strays from the ideal level, the sensor triggers adjustments to the amount of fuel injected into the system. This helps deliver optimal fuel efficiency along with a variety of other benefits, including easy starting, improved power and better reliability. And because EFI systems replace carburetors, users save on fuel costs while reducing downtime due to carburetor-related issues, including buildup or residue that can often occur when using ethanol-blended gasoline. Kohler was the first engine maker to release a closed-loop EFI engine, and the 824-cc Command PRO EFI is the next evolution in the company's lineup. "We've invested in a work-hour equivalent of six years of design simulation," Johansen said. "The 824 exceeds commercial-duty standards and is being released to the market after more than 27,500 hours of testing, so the Kohler team and our OEM partners are confident that the engine will offer lasting performance and durability." To support easy maintenance, all Kohler Command PRO EFI engines are supported by proprietary diagnostic software, which can be used to tap into an engine's critical performance data. The software provides automotive-grade diagnostic capabilities and a variety of information to help simplify upkeep and repairs, including a log of operating conditions, total hours, oil temperatures, detailed load parameters and more. Propane model also planned Along with the gasoline models, Kohler will also introduce 2 propane 824-cc Command PRO EFI engines: PCV850 and PCV860 (27 and 29 hp., respectively). Kohler is the only company in the industry to manufacture a closed-loop EFI engine designed and optimized for propane use, producing equivalent power and torque to carbureted gasoline engines. The factory-direct propane EFI models eliminate the need for less-effective aftermarket propane kits that typically need fuel adjustment and priming, and often don't perform as well. With propane prices averaging up to 20-40 percent better per BTU than gasoline, commercial users of the 824-cc Command PRO EFI propane engines can experience significant savings in their cost of fuel. Additionally, there are numerous incentives for using propane, including a $1,000 rebate from the Propane Education and Research Council (PERC) on new equipment purchases, additional state incentives of up to $2,500 offered by 11 states, and municipal incentives in many local areas. Since propane is a cleaner-burning fuel, the 824-cc Command Pro EFI propane model will be ideal for users in states that enforce Ozone Action Days, which limits mowing with carbureted gasoline engines. Propane-fueled equipment can also help commercial cutters win business contracts with municipalities and other organizations seeking "green" fuels and technologies. Kohler will produce the 824-cc Command PRO EFI models at its commercial plant in Kohler, Wis., using new computer numerical control (CNC) machining centers and a newly designed production line, and assembled by highly skilled Kohler associates.
