Comparison of Traditional and Alternative Fuel Engines

Abstract

Over the past one hundred years, traditional engine have an undeniable impact on the development of human civilization.It is precisely because of the invention of traditional engines that significant breakthroughs have been achieved in many fields. Nevertheless, the use of them contribute large amount of greenhouse gas, such as carbon dioxide. The emission of these gas significantly deteriorate global environment. Additionally, due to the excessive reliance of humans on traditional engines, a large amount of fossil energy has been consumed. The fuels used in traditional engines are mostly non-renewable fossil energy. Therefore, the use of traditional engines has always been detrimental to the sustainable development of humanity in the future. In response, alternative fuel engine (hybrid engine,battery electric engine,fuel cell engine), have developed by people. As time went by and with the development of the times, their appearance gradually replaced the use of traditional engines.In this era where both traditional engines and alternative fuel engines are indispensable, this article focuses on the analysis of their working principles, performance comparisons, advantages and disadvantages comparisons, as well as emissions comparisons.
