So what was his contribution?

His contribution is very significant in several ways, starting with his achievement in the field of chemistry. Curiously, his discovery was 66 years earlier than the first appearance of the diesel engine. Not only was he able to isolate chemical elements such as Beryllium or Aluminum, he was also able to synthesize a chemical substance that many living beings produce: UREA, the first component of animal origin to be created in a laboratory.

More than 150 years after this discovery, urea was used in combustion where the emission of NOx (nitrogen oxide) was already an environmental problem. So together with the SCR (Selective Catalytic Reduction) systems and the great discovery of Mr. Wöhler, we have been able to lower this type of pollutants to near zero. And in accordance with President Biden’s Executive Order, “Strengthening America’s Leadership in Clean Cars and Trucks,” more restrictions will follow in the coming years where it will be critical to increase pollutant reduction even further, despite today’s actual levels.

It would have been very difficult to deal with the production of urea through living beings. The human being, through urine, can only concentrate 9% of its volume, for example. Incidentally, the myth that human urine can be used in the DEF tank of a diesel unit with SCR (deadly to engines), is one of several fallacies that surround the world of motor transport. So a couple of quick tips: never pee in your DEF tank and of course, when you have Diesel Exhaust Fluid with required standards, pour it into the proper tank which IS NOT THE TANK WITH THE DIESEL, otherwise the tank will be contaminated and this can result in huge expenses for you.

So thanks to engineer Wöhler, Transliquid Technologies LLC. can implement its discovery for the benefit of diesel engine fleet owners by producing the highest quality API-certified Diesel Exhaust Fluid (DEF).
