剛看到某網站介紹說新款G30 520d 在加油孔旁有一個加尿素的孔，以後都要添加，
但問題Ad Blue尿素很容易取得嗎?
多少公里要添加一次?
如果沒添加會如何?
對環境肯定是好,另外純度有要求,幾百萬的車別省那點錢搞壞轉化觸媒
AdBlue ® – The reliable choice.
For several years, the Euro IV, V, VI Standard Emissions Regulations significantly restricted marginal values of exhaust gasses, specifically nitric oxide, from commercial vehicles. Recently, these restrictions included private vehicles. In order to reach these objectives, most European OEMs rely on the well-established Selective Catalytic Reduction (SCR) technology. AdBlue®by BASF can help reduce nitric oxide emissions.
How does AdBlue® by BASF work?
AdBlue® is a high purity, 32.5% urea solution directly injected into the exhaust gas where it serves as reducing agent. The released ammonia subsequently reacts with the nitric oxides on the catalyst to form elementary nitrogen and water; both are natural constituents of the air we breathe. Hence, the amount of nitric oxides in the emission can be reduced.
Reduced fuel consumption and constant engine output
The combination of SCR Catalysts with AdBlue® by BASF needs higher temperatures in the motor to elevate the exhaust gas temperature for the effective AdBlue NOX reduction. This leads to higher fuel efficiency and less unburned fuels and less sooty particles in the exhaust gases without affecting engine output.
