Honda EU7000is Inverter Technology
Inverter Technology and the EU7000is
The EU7000is is not only portable at a dry weight of 262 lbs., but like other smaller EU models, the all-new model incorporates inverter technology that delivers clean, high quality electricity that is optimal for powering the ever-increasing number and types of sensitive electronics. For example, computers and power-sensitive testing equipment often operate best with "clean power" – consistent electrical current that has a stable sine wave or signal. A computer without clean power would likely either freeze, shut down, or be interrupted.
The raw power produced by the generator flows through power semi-conductors, which are controlled by a microprocessor. This process provides ultra-clean power with a sine wave equal to or better than AC current from a standard household wall outlet.
The development of inverter technology also has allowed Honda to substantially reduce weight and noise, even more important in larger, more powerful generator models.
By eliminating the standard alternator, Honda's inverter generator models weigh 50 percent less and are 1/3 smaller in size than traditional generators. The Eco Throttle™ feature allows these generators to conserve fuel by varying engine RPM to produce only the power required to operate the equipment, improving fuel economy up to 40 percent.The inverter technology of the EU7000is creates a waveform with a distortion factor of less than 2.5 percent. The newest addition to the Honda generator lineup is yet another solution to customers' demand for high quality portable power back-up for residential, recreational and many other related applications.
The Power Behind the Innovation
The EU7000is and the GX390 Engine
In keeping with the Honda no-compromise philosophy, the new EU7000is generator features an advanced 4-cycle power system, the Honda GX390, which provides a quiet, low-emission and reliable source to power a variety of different construction, maintenance and premium power equipment, including generators. The overhead valve (OHV) GX390, one of the most technologically advanced Honda engines, is the largest work-horse in the Honda industrial engine lineup. It incorporates the company's latest design and manufacturing features.
|Model||GX390 (horizontal shaft)|
|Engine Type||Air-cooled 4-stroke OHV single cylinder|
|Net Torque||19.5 ft.-lb. (26.4 Nm) @ 2,500 rpm|
|Ignition System||Digital CDI with variable timing|
|Air Cleaner||Dual element|
|Oil Capacity||1.16 U.S. qts. (1.1 liters)|
|Fuel Tank Capacity||6.4 U.S. qts./6.1 liters|
|Dimensions (LxWxH)||16 in. x 19.1 in. x 17.7 in. (407 x 485 x 449 mm)|
|Dry Weight (dry)||69 lbs. (31.5 kg)|
The GX390 engine provides EU7000is owners (and their friends and neighbors) with a quiet yet powerful and lightweight source of power for a variety of demanding back-up power applications. In particular, the quiet operation offered by the engine's timing gears results in greatly improved sound quality. Honda engineering also has reduced valve train and gear noise for a better quality engine sound that is distinctly easier on the ears.
Low emissions mean more than just preserving the environment in general. The GX390 incorporates an innovative combination of a compact combustion chamber and overhead valve configuration that significantly reduces fuel and oil consumption as compared to conventional side-valve engines. This configuration also reduces many potential maintenance needs, making the Honda GX390 one of the most efficient, cost-effective engines available. The result is a quieter, easier starting engine that delivers a more pleasant experience for consumers.
Other Consumer Benefits
One of the great frustrations of using a generator can come from simply trying to get the machine to start. The Honda GX390 minimizes this annoyance through high-quality manufacturing and by special features designed to improve starting reliability. The GX390 incorporates, for example, a horizontal cross-flow intake port that smoothes the flow of fuel into the combustion chamber. This feature, combined with Honda's automatic mechanical decompression, eliminates many of the causes of starting problems.
Breakdowns provide another source of frustration and expense. Honda minimizes the cost of owning a generator through advanced design technology and through the legendary quality of its manufacturing process. The GX390 has a unique configuration that creates a lighter and more compact package than anything else in its class. This engine design also minimizes the number of moving parts – sources of potential breakdowns – making the engine more reliable and easier to operate.
One Engine for All
Honda continuously works to meet future, lower EPA and CARB standards regarding the performance of its products. In January 2007, Honda Engines began certifying its models to the new, lower California Air Resources Board (CARB) 2007 standards, existing EPA Phase 2 emission requirements and offering 50 state compliant engines. Investing in meeting the strictest of environmental requirements in the development of one engine for use in all 50 states reflects Honda's forward thinking on emission regulations, air quality and the needs of its customers. Moreover, Honda engines meet the new CARB exhaust and evaporative emissions requirements without the use of a catalytic converter.
As a result, the overall emission levels from Honda engines have been reduced by more than 32 percent as compared to 1995. Further, the EPA implemented a new emission control program to reduce hydrocarbon emissions from small spark-ignition engines by approximately 35 percent. Honda engines are in compliance with the current EPA Phase 3 standards (for both exhaust and evaporate emissions).
