A Bibliometric Review of Alcohol–Diesel Blend in CI Engines

Abstract

A large number of diesel engine applications in the transportation and agriculture sector has become a major concern for environmental pollution. It is quite difficult to improve diesel engine performance and at the same time controlling its emissions effectively. There are various methods to achieve the same e.g., changes in engine design, fuel blending with additives, engine exhaust treatment, etc. The most practical technique for controlling high emissions without degrading engine performance is to modify fuel with additives. Alcohols are the most promising additives which have been used by various researchers worldwide. In the current study, a bibliometric-based study and the role of various alcohol additives in improving combustion, performance, and fumes outflow qualities of CI engines were comprehensively reviewed. Due to higher oxygen levels in the combustion zone, it was found that combining diesel with alcohol reduces the emissions of CO2, CO, HC, soot, and particle matter.
