Traditional Engines Versus All Kind of Alternatives

Abstract

Nowadays, driven by the transformation of global energy structure and the goal of ‘carbon peaking’ and ‘carbon neutrality’, renewable energy industries are growing exponentially, the technical path selection of new energy power systems (including pure electricity, hybrid, hydrogen fuel cells, etc.) has become the core of research in the field of transportation. Although the renewable energy has a mature technology, there are still several issues need to be solved. The internal combustion engine power system still has advantages in terms of long endurance, high-load adaptability and existing infrastructure compatibility. In contrast, the pure electric system is limited by battery life and charging infrastructure coverage, and the hydrogen fuel cell systems faces the bottleneck of high hydrogen storage costs and insufficient layout of hydrogen filling stations. This paper will demonstrate the structure of different kinds of engines, comparison through various factors, and the future developing trend.
