We immediately think of oil and coolant containment—oil seals, O-rings, and gaskets—in this connection. But combustion gas is the fluid that produces power, so we have to add the sealing functions of piston rings, and intake and exhaust valves to our list.

Greenwashing- Cuando de repente todas las marcas son verdes, veganas y feministas
Bastantes empresas están iniciando una política de limpieza de imagen con el uso en las redes sociales y grandes medios de «noticias de empresa», premios, comunicados lemas y rótulos destinados a que los receptores de sus mensajes sepamos las cosas que dicen hacer para acercarse a los ideales ecológicos de una inmensa mayoría de personas.
