恐竜から学ぶ内燃機関進化の方向性

抄録

Current internal combustion engine situation seems to be similar with the dinosaur situation in the end of the Cretaceous period. After a powerful prosperity due to diversification and enlargement, dinosaurs are said to be extinct without being able to endure large environmental changes. Mammals, which were predator biological in weakness in the age of dinosaur prosperity, flourish in later times. The presence of current battery EV is reminiscent of Cretaceous mammals. Because of the historical knowledge, it is imagined that internal combustion engines will be extinct like dinosaurs and that BEV will prosper. However, there is the theory that it is said that the dinosaurs are extinct but part of them have survived and evolved into birds. The point of their survival and evolution is considered the following three factors of “Small and light”, “Homeothermic” and “Wings”. Here, hints on the survival of internal combustion engine want to be obtained from the evolution of dinosaurs.
