之多。
EPA: 482K VW diesel vehicles violated emissions rules
12:28 p.m. EDT September 18, 2015
EPA said the vehicles software “detects when the car is undergoing official
emissions testing, and turns full emissions controls on only during the
test.” The vehicles include diesel Golf, Jetta, Sportwagen, Beetle and Audi
A3 vehicles built from 2009-2015.
EPA said “the effectiveness of these vehicles’ pollution emissions control
devices is greatly reduced during all normal driving situations. This
results in cars that meet emissions standards in the laboratory or testing
station, but during normal operation, emit nitrogen oxides, or NOx, at up to
40 times the standard. The software produced by Volkswagen is a ‘defeat
device,’ as defined by the Clean Air Act.” |

S**C 发帖数: 2964 | 28 One possibility is currently EU and U.S. regulations are a bit different. EU
is tight on PM, while U.S. is tight on NOx. If your engine runs at higher
temperature, it will have high NOx and low PM, and higher efficiency. In EPA
regulated cycle test, VW could let engine to run colder, thus lower NOx and
higher PM, and meet EPA regulation. In EU driving cycle NEDC and normal
driving, just let engine run hotter, high NOx which is not an issue and low
PM.

老外网站荷兰人留言说,早就觉得柴油车有问题。自从满地都是环保柴油车之后,空气
质量明显恶化,他们自行车都没法骑了…… |
s********r 发帖数: 2308 | 39 底特律因为一直不产小柴油车,所以推动EPA标准把柴油小车的排放标准弄得特别严苛
,远超欧洲标准,同时给柴油卡车的又特别宽松。一直以来德国的小柴油车很难进入美
国市场,后来加成本弄了adblue才进来了。我猜这次epa发现问题背后没准就有三大中
的某一家的贡献,说不定就是对柴油小车比较熟悉的Fiat-Chrysler。
6缸车没这个问题我猜是VW觉得买6缸车的人对mpg不那么敏感?
这次被screw的人除了人民汽车,还有那些加装ECU芯片的车主和做了DPF delete的猛人
们。这一下子肯定对TDI的车的emission inspection会更细致,会更容易被发现。 |
