Non-road engine

Non-road engines are engines that are used for other purposes than a motor vehicle that is used on a public roadway. The term is commonly used by regulators to classify the engines in order to control their emissions. Non-road engines are used in a wide range of applications which may include machinery and non-road vehicles. 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. The definition of non-road engine may explicitly exclude certain non-road vehicles such as aircraft, locomotives, and ocean-going marine vessels. 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 cold chain transport vehicles forklifts, generators, and compressors using gasoline or propane recreational boats and personal watercraft non-road 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, stationary engines that are diesel powered may be classified as non-road engines. United States emission standards and European emission standards The rationale for establishing emission standards for non-road engines is that they are a significant source of pollution. The engines of on-road vehicles have advanced emission controls which are not found on those non-road engines. The non-road engines also emit air pollution particles at much higher rates. The emission standards are based on the engine classifications and vary in various jurisdictions. The main model regulations that are used by many countries are the United States Environmental Protection Agency through the section 213 of the Clean Air Act (42 U.S.C.
