original question: what Engine used [Gasoline] and [Compressed natural gas] as fuels?
answer: gm small gasoline engine
answer type: Engine.
auxiliary information: Gasoline /Àà…°√¶s…ôliÀên/, also known as petrol /Ààp…õtr…ôl/ outside of North America, is a transparent, petroleum-derived liquid that is used primarily as a fuel in internal combustion engines. It consists mostly of organic compounds obtained by the fractional distillation of petroleum, enhanced with a variety of additives. A 42-gallon barrel of crude oil yields about 19 gallons of gasoline, when processed in an oil refinery. The characteristic of a particular gasoline blend to resist igniting too early is measured by its octane rating. Gasoline is produced in several grades of octane rating. Tetraethyllead and other lead compounds are no longer used in most areas to regulate and increase octane-rating, but many other additives are put into gasoline to improve its chemical stability, control corrosiveness and provide fuel system 'cleaning,' and determine performance characteristics under intended use. Sometimes, gasoline also contains ethanol as an alternative fuel, for economic or environmental reasons.Compressed natural gas:;Type: Fuel. ;
