Non-road engine (which may include non-road equipment and non-road vehicle) is an internal combustion engine or a gas turbine engine used for other purposes than being an engine of a vehicle operated on public roadways. The term is commonly used by regulators to classify the engines in order to control their emission. Non-road engines are used in an extremely wide range of applications which may include machinery and engines of vehicles in other modes of transportation with different fuel types such as gasoline and diesel fuel.〔(【引用サイトリンク】url=http://www.epa.gov/nonroad/ )〕〔 ("Nonroad Engine Population Estimates" ) US Environment Protection Agency. Retrieved 27 April 2014.〕 In many jurisdictions, the term non-road engine is assumed to refer to the engines that have mobility or portability which is separated from the term stationary engine.〔(【引用サイトリンク】url=http://www.gsgnet.net/gsgpdfs/EmissionsStandards.pdf )〕 The definition of non-road engine may explicitly exclude certain non-road vehicles such as aircraft, locomotives, and ocean-going marine vessels. In Europe, the regulations are specifically clarified on the mobility by using the term non-road mobile machinery.〔(【引用サイトリンク】url=http://ec.europa.eu/enterprise/sectors/mechanical/non-road-mobile-machinery/index_en.htm )〕 In Australia, the definition includes some stationary engines such as electric generators and pumps.〔(【引用サイトリンク】url=http://www.environment.gov.au/topics/environment-protection/air-quality/non-road-engines )〕 ==Classifications== There are many classifications of the non-road engines based on the jurisdictions. The following are common classifications:〔〔 * Lawn mowers and garden equipment * Snowmobiles, dirt bikes, and all-terrain vehicles * Forklifts, generators, and compressors using gasoline or propane * Recreational boats and personal watercraft * Nonroad diesel engines (machinery) in construction and agricultural equipment such as backhoes and tractors. Other equipment are included such as ground support equipment, and heavy forklifts, generators and pumps that use diesel engines. * Marine diesel engine * Locomotive * Aircraft engine In certain jurisdictions, the non-road engines may include stationary engines that are diesel powered.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Non-road engine」の詳細全文を読む スポンサード リンク
