Comparative Analysis of Traditional and Hybrid Engines: Efficiency and Emissions

Abstract

As two dominant types of automotive engines, traditional internal combustion engines and hybrid engines hold significant market shares. This paper focuses on comparing the efficiency and emissions of these two engine types. The traditional engine, characterized by its crankshaft linkage structure, presents both its best feature and its biggest drawback. This structure leads to substantial efficiency losses and increased combustion time, resulting in lower overall efficiency and higher environmental pollution compared to hybrid engines. On the other hand, hybrid engines boast a more intelligent system, offering three distinct modes that can be selected based on the required power. This flexibility enables hybrid engines to conserve energy more effectively, thereby achieving higher efficiency. Regarding emissions, hybrid engines can switch between electric power and internal combustion depending on the situation, resulting in healthier emissions profiles. This paper aims to elucidate the operational differences and environmental impacts of traditional and hybrid engines, encouraging readers to form their own opinions on potential improvements for these technologies.
