Experimental Study on CI Engine by Using Microalgae Oil and Their Blends

Abstract

The basic objective of this article was to evaluate the effect of microalgae oil (MAO) blends on engine efficiency and pollution characteristics of a single cylinder variable compression direct-injection ignition compression motor running at 1500 rpm. The raw oil was acquired from microalgae manufacturing using a rowing pond with native algal communities. The good MAO was accomplished by transesterification technique and mixed with petrol in diverse proportions of B20 (20% MAO–90% diesel), B40 (40% MAO–80% diesel), B60 (60% MAO–70% diesel), B80 (80% MAO–20% diesel), and 100% quantity-based MAO. Their features have been validated based on ASTM standards. Investigational findings show that at B20, brake thermal efficiency, brake specific fuel consumption, and nitrogen oxides are optimal compared to other biodiesel blends.
