| Abstract from DBPedia | Exhaust gas or flue gas is emitted as a result of the combustion of fuels such as natural gas, gasoline (petrol), diesel fuel, fuel oil, biodiesel blends, or coal. According to the type of engine, it is discharged into the atmosphere through an exhaust pipe, flue gas stack, or propelling nozzle. It often disperses downwind in a pattern called an exhaust plume. It is a major component of motor vehicle emissions (and from stationary internal combustion engines), which can also include crankcase blow-by and evaporation of unused gasoline. Motor vehicle emissions contribute to air pollution and are a major ingredient in the creation of smog in some large cities. A 2013 study by the Massachusetts Institute of Technology (MIT) indicates that 53,000 early deaths occur per year in the United States alone because of vehicle emissions. According to another study from the same university, traffic fumes alone cause the death of 5,000 people every year just in the United Kingdom.排気ガス（はいきガス、英: exhaust gas）は、ガソリン・軽油などの燃料がエンジンで燃焼したり、さまざまな化学反応を起こしたりしたことで生ずる気体で、大気中に放出されるものを指す。 自動車用語では排気 (exhaust)、または排ガス・排出ガス（共にexhaust gas）とも言う。日本産業規格 (JIS D0108) では、ブローバイガスや（ガソリンベーパー）などエンジンの燃焼に伴うもの以外を併せて、排出ガス (emission gas) と総称して区別している。 (Source: http://dbpedia.org/resource/Exhaust_gas) |
