Diesel exhaust gases without any nitric oxides is that possible?
The scandal surrounding VW has thrust nitric oxide (NOx) emissions from diesel vehicles into the limelight. Owing to the different engine technologies, these have always been higher than in gasoline-powered cars. On the other hand, diesel consumes less fuel. If a way can be found to denitrify diesel emissions efficiently, we would have an economical, clean engine. Empa researchers are thus working hard on optimizing the catalytic converter technology for diesel.
In collaboration with the start-up "Polarmond", scientists at Empa developed an «all-in-one» shelter system. Inside the shelter conditions remain comfortable whatever the weather outdoors, thanks to a sophisticated dehumidifying system and a fine-tuned temperature control mechanism.
Inhalation anesthetics, so-called fluranes, are widely used during surgery. Just how much of these strong greenhouse gases is produced worldwide remains a mystery; industry is keeping its cards close to its chest.
