@WOC: Honda’s First EFI Generator Introduced

Posted on January 22, 2014

Honda Power Equipment is debuting its first electronic fuel injected (EFI) generator, the all-new model EU7000is portable generator.  Introduced at this week’s World of Concrete show and due for production later this year—May being the target—the new model joins Honda’s Super Quiet Series. 

Honda’s Tom Pernice would not comment if this was the first of multiple EFI launches for Honda, other than to say the company was looking at other applications for the technology.

Seen as applicable for a range of commercial and residential applications, as well as rental, the Honda EU7000is is the company’s first application of electronic fuel injection to a generator, resulting in greater fuel efficiency, easy starting without the need for a choke, and longer operating times than the model it replaces.  Electronic fuel injection also allows for longer-term fuel storage than a carbureted model, Honda said.   What’s more, the all-new generator incorporates a one-touch, push button electric start switch. 

“The EU7000is marks the further evolution of the Honda Super Quiet Series of generators through its continued development in the areas of output, noise, size and fuel consumption.  Producing 7,000 volt amperes (VA) ― or watts ― of power, this all-new generator is the solution to a variety of power needs,” said Scott Conner, senior vice president at Honda Power Equipment. “The EU7000is is equally applicable for home backup use, on a commercial worksite, campsite or for RV camping and tailgating due to its excellent portability, quiet power output, and compact design.” 

The EU7000is has a dry weight of 262 lbs. only two pounds heavier than the Honda EU6500is generator.  The new model also is equipped with a new 5.1 gallon gas tank and can operate for six hours per tankful of gas at rated load or an estimated 18 hours at ¼ load. This allows the generator to achieve a 25 percent increase in run time and a 20 percent increase in fuel economy over the EU6500is model, Honda said.  By utilizing a separate triple chamber construction comprised of an exhaust (muffler) chamber, an engine chamber, and an intake chamber and the Eco-Throttle design, the EU7000is achieves a noise level of approximately 60 dB at rated load.

Power quality was also a key design criteria.  As such, the EU7000is offers a maximum 7000 VA of enhanced commercial grade electricity with a wave form distortion factor of less than 2.5 percent. 

In addition, the new EU7000is incorporates the Honda inverter technology, designed to power computers and sensitive electronic equipment that require consistent electrical current with a stable sine wave or signal.  A computer, or other equipment operating on fluctuating power could possibly freeze, shut down, or be interrupted. To overcome this problem, Honda engineers developed a form of inverter technology, which allows generators with this technology to provide cleaner current to power electronic equipment in remote locations.  In addition, inverter technology substantially reduces weight and noise.

The EU7000is includes a wheel kit with large semi-pneumatic tires and folding handles as standard equipment.  Additionally, an iMonitor digital display provides operational information such as hours of use, performance data, battery charging status and other on-board diagnostics.

The power behind the EU7000is is the Honda fuel injected OHV GX390 engine.  As is the case with all Honda engines, the GX390 provides low-emission, 4-cycle power to the unit.
