The paper I linked "sampled ... 56% of all passenger cars sold in Europe in 2016". So they all have this stuff, right?
Maybe next year's models will actually use it fully, and become clean. I'm not holding my breath though, it seems like a political problem. And if they do use it fully, in the real world, will they still be more CO2 efficient, and by how much? After all, the efficiency measure is the major incentive for all this cheating.
- namibj 8y agoAdBlue is usually made from natural gas, so one has to figure the CO2 it takes into it. It should be able to use less diesel fuel, but I don't know if the reduction there is worth the increase in AdBlue use. The hotter the engine burns, which in this case should mean the higher the compression/inlet pressure is, the higher the efficiency, as well as the NOx levels generated. The impact of particle filters on engine efficiency is not know to me.
