sao bác này biết mình ko ở Mỹ mà phát ngôn éo với chả đéo. ỷ bản thân đặt tên California, cho mình là người Mỹ thì coi tất cả thành viên trong otosaigon là sống ở VN hết hay sao, ai phát biểu gì về Mỹ mà bản thân lậm Mỹ quá nên cho là nó đúng hết àh.
Fail smog check thì tất nhiên ko thể lưu thông , nhưng Pass smog check thì cần mie gì lo, có từng thấy mấy tiệm sửa xe ở gắn slogan Smog Check! No Pass No Pay chưa. nhục.
Xem đi để biết xem tiêu chuẫn khí thải của Mỹ và châu Âu, thằng nào găt gao hơn thằng nào nhé

“Europe has for light duty vehicles different emission limits for petrol and diesel vehicles. For Euro 5 diesel vehicle (from September 2009) the NOx limit is 0.18 g/km; Euro 6 from September 2014 is 0.08 g/km,” he said via e-mail. “In the U.S. they have different ‘tiers’ and a very different test cycle. As I understand it a manufacturer of vehicles must ensure the
fleet average is below 0.07g/mile (0.04 g/km), i.e. no specific limit for diesels. On balance the USA tend to be ahead of Europe in terms of setting emission limits.
· U.S. emissions laws require all vehicles and fuels to comply with the same requirements (fuel neutral)
· U.S. emissions laws require significantly cleaner vehicles with longer emissions warranty periods, with advanced on-board diagnostics (OBDII) including 13 diagnostics for emissions; the EU’s diagnostic requirements are far less extensive and do not fully correlate with emissions
· The testing cycles in the U.S. encompass a far greater range of operation (altitude, high temps, etc.) requiring emissions performance from -10 to 95F than does Europe; the U.S. requires emissions durability for 120,000 miles/10 years; EU 62,500 miles/5 years
· The U.S. certifies vehicle emissions on a fleet-wide average basis. The EU does not use such a fleet-wide basis.
· The EU is focusing more on the number of particles emitted and the US on the mass of particles emitted.
Vậy dám khẳng định tiêu chuẩn khí thải của châu Âu cao hơn Mỹ à ?
Tiêu chuẩn khí thải của Mỹ họ cập nhận liên tục chứ có đứng yên 1 chỗ mà dám khẳng đinh tiêu chuẩn khí thải của Mỹ thua châu Âu.

And then there's another challenge for diesels--stricter U.S. emission regulations. The 50-state light-duty vehicle limit for emissions of nitrogen oxides is 0.07 grams per mile. In Western Europe, the limit is 0.29. Reducing NOx to nitrogen and oxygen is much harder with a diesel engine because the exhaust is typically cooler and contains less oxygen compared to a gas engine. To meet U.S. regulations, diesel engines are required to use complicated--and expensive--
high-pressure fuel injection and after-treatment systems that in some cases inject an aqueous urea solution to handle the NOx. The added expense of course means an even longer payback period for the consumer.
