Emission Analysis of Chlorella sp. Microalgae Biodiesel with Oxide Nano Additives in Diesel Engine

Abstract

The Chlorella sp. biodiesel was produced from the microalgae oil via transesterification process. Three combinations were studied. Blend of biodiesel (20%) with diesel (80%) was prepared and denoted as B20. Then the TiO₂ nanoparticles were added to each B20 blend samples in a quantity of 50 and 100 ppm using an ultrasonicator. In compliance with the American Society for Testing and Materials (ASTM) fuel requirements, the biodiesel blends have been characterized. In an unaltered four-stroke diesel engine using various loads, the biodiesel blends were studied. The experimental outcomes show a decrease in exhaust emissions in terms of CO, HC, NOx, and Smoke.
