La proposta did\u00e0ctica \u201cEls motors d\u2019explosi\u00f3, una soluci\u00f3 a un problema\u201d permet abordar el contingut curricular espec\u00edfic dels motors de combusti\u00f3 de 3r d\u2019ESO de Tecnologia, alhora que integra coneixements de Matem\u00e0tiques i de Ci\u00e8ncies \u2013qu\u00edmica- Aquesta transversalitat fa que pugui considerar-se una unitat amb possible orientaci\u00f3 STEAM.<\/p>\n

El desenvolupament de l\u2019activitat necessita la construcci\u00f3 de dos models manipulables de maquetes de motors. Una del motor de 4T de cicle Otto i una altra del cicle del motor de 4T Diesel. Es faciliten totes les peces en format STL per a ser impresses en 3D per muntar els dos tipus de motors.<\/p>\n

El tema dels motors d’explosi\u00f3 s’aborda vinculat-lo al tipus de combustibles que empren cada un d’ells i amb els gasos de combusti\u00f3 que generen. Tot relacionat-los amb el problema de l’emissi\u00f3 de CO2 i l’efecte hivernacle, i els NOx i micropart\u00edcules que impacten negativament sobre la qualitat de l’aire. Aquest \u00e9s el contrasentit que tenim com a societat, un invent que ha afavorit la mobilitat i el transport de mercaderies ha esdevingut un problema d’abast planetari i local a les grans ciutats.<\/p>\n

A partir del coneixement tecnocient\u00edfic sobre els motors es planteja la controv\u00e8rsia a l’alumnat per tal que es posicioni i entengui les mesures que es van prenent per acotar l’\u00fas de combustibles f\u00f2ssils i la necessitat d’anar cap a alternatives no contaminants.<\/p>\n
