Bjective was to highlight the part with the cavitation phenomenon inside an injector on the functionality of a combustion engine. Within the methodology used, it was a question of acquiring probably the most relevant articles in the period from 1970 to 2021 as outlined by specific key phrases. This identified 66 articles. In view of your research obtained, it has been shown that a lot of the function bargains with cavitation from the point of view of fluid mechanics (63) with no associating combustion (37). Certainly, it truly is shown that the phenomenon of cavitation has damaging effects around the flow of fuel inside the injector, on the formation of spray, and around the atomization of your fuel. It has also been shown that biofuels, as a substitute for typical fuels, have advantages concerning this cavitation phenomenon. Certainly, it has been shown that the latter usually cavitate much less due, to their greater viscosity; as a result, these is often a resolution to the difficulty posed, specifically due to the fact this sort of fuel is promising with regards to carbon footprint. Other studies have attempted to hyperlink the effects of cavitation around the combustion procedure by focusing around the impact of fuel sort on combustion efficiency and propose solutions like hybrid fuel blending, adding additives to neutralize the effects of temperature, andEnergies 2021, 14,30 ofultrasonic treatment of fuel to decrease NOx, CO, and unburned gases. These studies were carried out without the need of direct interaction between the cavitation phenomenon as well as the combustion course of action and represent a minority quantity, compared with all studies dealing with the effects of cavitation in heat engines. This observation makes it possible to justify the lack of research within this theme along with the significance of bringing new knowledge on the function of cavitation in an injector on the efficiency of combustion. For this, it could be achievable to characterize the efficiency of combustion in line with the level of cavitation.Author Contributions: Conceptualization, K.C. and N.G.; methodology, K.C. and B.M.; investigation, K.C., N.G., B.M. and L.L.; resources, L.L.; original draft preparation, L.L.; writing–review editing, K.C., N.G., B.M. and L.L.; supervision, K.C. and B.M.
