Small engine : ウィキペディア英語版 | Small engine
A small engine is the general term for a wide range of internal combustion engines used to power lawn mowers, generators, concrete mixers and many other machines that require independent power sources. Most small engines are single-cylinder, with a few V-twin units. Although much less common, there have been small Wankel (rotary) engines manufactured for use on lawn mowers and other such equipment.〔("Now You Can 'Mow' with a Wankel!" ''Popular Science'', July 1973 p. 18 )〕 ==Power range== The engines, which may be of two or four-stroke design, are small in both physical dimensions and power output, relative to larger automobile engines. Power output ranges from less than 1 to about 15 horsepower. The smallest of all are used in handheld garden machinery, such as string trimmers and chainsaws, which may be as small as piston displacement. The most common are four-stroke air-cooled single-cylinder engines running on either petrol or diesel.〔(One-cylinder Diesel engines )〕
