The 3^rd edition of Diesel Powertrains 3.0 took place on the 11^th and 12^th of July in Ludwigsburg, Germany. This conference offered multiple opportunities for mutual exchange between engineering experts and industry representatives working on current and future powertrains, Diesel powertrain layout and configuration or in the fields of Diesel engine development and their formulation. The Diesel Powertrains 3.0 Scientific Committee selected Mr. Isaac Valls’ topic as one of the presentation titles to be included into the conference program, so he participated with his speech titled “High thermal conductivity tool steels HTCS® to increase the strength-to-weight ratio and the process productivity of the casted light alloys power train components”.
