The advent of electro-mobility has led to an industrial upheaval in the field of automotive production. In the past there were basically two types of engines: diesel and gasoline. In the last three or four years we have been hearing more and more about BEV, HEV, PEHV, and FCEV. This simple change in nomenclature has led to an epochal technological revolution under the hoods.
The automotive industry has always had the objective of improving performance while simultaneously reducing the environmental impact of cars. For traditional ICE engines, the increase in performance and the reduction of pollutants have been achieved by producing increasingly precise components (crankshafts, camshafts, pistons, etc.), which have allowed the reduction of fuel consumption, obtaining a secondary benefit of reducing polluting emissions.
