Social Utopias and Engineering Design

Czajkowski Waldemar

Multidisciplinary Aspects of Production Engineering

2020

Vol. 3, Iss. 1

570--583

A paradox of our time is identified: on the one hand – the development of one global system (ecological, technological and social), on the other hand – the still increasing “balkanization” of science. The dynamics of this systems is a source of well-known numerous global problems. Its possibly effective solution needs adequate knowledge about the system. For this reason, counteraction to “balkanization” of science is of great practical importance. And this counteraction should comprise not only development of “transboundary” sciences (such as biochemistry or social psychology) but also establishing and developing links between very distant disciplines. This text is intended as a contribution to linking social and engineering sciences. The notion of design plays the central role in this text. Its meaning in the engineering sciences. The notion of utopia has been chosen as a partial counterpart to the term of engineering design. This notion was defined using a concept of possible world – taken from modal logic. It encompasses two ideas: this of design and that of prediction, It is claimed that we need many utopias and that their plurality is of fundamental importance for protecting us against the threats of utopianism. The paper suggests that social utopias can play a heuristic role in engineering design (particularly in the initial phase of defining technological problems), and – on the other hand – that the theory of engineering design can be supportive for, badly needed, development of methodology of utopias creation.

The challenges of the future light-duty vehicles and powertrains: energy sources, global warming, emissions and world-wide competition

Bielaczyc P.

Silniki Spalinowe

2009

R. 48, SC1

363--374

Development trends for light-duty vehicles and powertrains in aspects of available energy sources and global energy consumption, reduction of greenhouse gas emissions, global warming and global CO2 legislation target, world-wide emissions regulatory approach, crude oil prices, fossil and alternative fuels startegy, advanced propulsion technology srtategy, global vehicle production and competition, economic and finacial crisis influence on automotive industry are presented in the paper. The main drivers that have influence on future powertarin technology choices and personal transportation are described and discussed.

W artykule przedstawiono trendy rozwojowe dla pojazdów samochodowych i ich układów napędowych w aspekcie dostepnych zródeł energii i jej światowego zapotrzebowania, ograniczenia emisji gazów cieplarniaych i wprowadzania limitów emisji CO2, przepisów dotyczących ograniczania emisji zwiazków szkodliwych spalin, dostępnych paliw silnikowych i paliw alternatywnych, zaawansowanych konstrukcji układów napędowych, światowej konkurencji w produkcji samochodów, wpływuświatowego kryzysu finansowego i gospodarczego. Przedstwiono analizę głównych czynników technicznych i ekonomicznych wpływających na nowe rozwiązania stosowane w układach napędowych przyszłych samochodów osobowych i użytkowych.
