Since the production of the first diesel truck in 1924, and the first diesel car in 1936, Bosch has been one of the world’s leading providers of diesel technology. The exhaust-gas treatment and dosing system, Denoxtronic, is being used in a larger number of diesel vehicles than ever before. Therefore, it is growing in importance, and thus, potential for the workshop. The system works by injecting an aqueous urea solution known as Diesel Exhaust Fluid (DEF/AdBlue) into the exhaust stream and, in combination with the SCR catalytic converter, converts harmful nitrogen oxides (NOx) into water and nitrogen.
