Experimental Investigations of Metal Oxide Nano-Additives on Working Characteristics of CI Engine

摘要

Biodiesel is a potential substitute for diesel and extensive research is carried in India on production and utilization of biodiesel from a variety of edible/non-edible, animal fat and waste oils. However, issues like stability, clogging, increased NO_x, and high consumption rate etc. are some of the critical issues which are associated with long-term use of these alternative fuels in a diesel engine. The recent developments in science and technology may have concreted a method to create nano measure vigorous resources that have incredible benefits to micron sized constituents. Nano liquids may be a fresh period of compact-fluid complex constituents comprising of nano sized concrete elements disseminated into a base liquid. The present study investigates the effect of doping metal oxides nanoparticles with waste fish oil-based biodiesel. For the present study, the blends of fuel are prepared by using 30ppm each of titanium dioxide and alumina nanoparticles respectively. The addition of nano-additives in biodiesel is achieved using an ultra sonicator, to achieve unvarying postponement. A series of experiments have been conducted to evaluate the performance and emission characteristics of single cylinder direct injection (DI) diesel engine with four different energy samples containing biodiesel-diesel (B20), biodiesel-diesel-nano particles (B20Ti30), (B20Al30) and biodiesel-nano particles (B20Ti30Al30). Thermo-physical assets of the energy examples, including density, viscosity along with calorific values are also determined.
