“…However, since ethanol and oil do not mix well, research shows only certain types of 2-stroke oil can work well with bioethanol and the ratio between the two also must be controlled at 1/50. Other bioethanol-based fuels have also been developed for harsh environments such as isobutanol-extended fuel for marine outboard engines [10,11].…”

In a world that is gradually moving towards renewable sources of energy, the 2-stroke motor with it is low efficiency and high emission is being phased out. However, there are some applications which require the unique characteristics of the 2-stroke motor, making it the only suitable form of power for those applications. This paper will discuss the operating principle of the 2-stroke motor, how its construction is able to be simplistic and light, and how it has a high power-to-weight ratio. This paper will also discuss the relatively inefficient scavenging process caused by the simplistic nature of the 2-stroke engine, leading to high emission, low efficiency, short engine life, and noise. To solve these problems, mechanical solutions such as electronically controlled direct injection, delayed charging, and variable compression have been developed and are now common, while recent research into the use of bioethanol and hydrogen as fuel can further decrease emissions and increase efficiency. Therefore, the purpose of this paper is to summarize past and recent research regarding the strengths and limitations of 2-stroke internal combustion engines and the future developmental direction of 2-stroke engines in alternative fuel.

“…There has been concern that ethanol blends may significantly challenge these engines because ethanol may dilute the oil present in the fuel-oil blend that lubricates bearings in the engine crankcase. However, recent research for two-stroke engines with blends in the range of E15 to E20 did not reveal significant durability issues (Loesche 2017;Özer 2019;Yao et al 2010;Hilbert 2011;Miers and Blough 2013;Jandl et al 2018;Küüt et al 2020). Two-stroke engines have been phasing out of production in the last decade because of more stringent emissions requirements (Kamakaté 2009).…”
