Gas-fueled portable generators are generally the least expensive and the most popular among homeowners. Statistics shows that most consumers buy light-duty low-cost models for home use. A report published several years ago by Frost and Sullivan indicated that more then half of all light duty portable gensets in U.S. are purchased by consumers. At this, more then 98% of purchased portables were gas-powered. Such gensets are currently available in output power range from 500 W to almost 20 kW, with the most popular size being 3 to 10 kW.
Small models are normally powered by 3600 RPM (for the US market) air-cooled, twin cylinder lawn mower type engines. Such RPM is needed to produce 60Hz voltage. Technically speaking, these engines are internal combustion, spark-ignition engines that burn fuel in an enclosed cylinder. The engine's power is produced by the expansion of gases formed by the combustion of a compressed air-fuel mixture. A typical mid-power model has 4 to 8 gallon fuel tank sufficient for 5 to 8 hours run time at rated load. |
