Experimental Investigation on the Performance and Emission Characteristics of Di-Diesel Engine Using Diesel-Ethanol Blends with Aqueous Cerium Oxide Nanofluid as Additive

Abstract

The paper presents an experimental investigation, to evaluate the performance and emission characteristics of a direct injection diesel engine using diesel-ethanol blends with aqueous cerium oxide nano fluid (ACN) as additive at different load conditions. The test fuel (D85E15ACN) prepared using ultrasonic sonicator, contains diesel 85%, ethanol 15% (D85+E15) by volume, with 1ml of aqueous cerium oxide nanofluid (ACN) added with the blend. The results show that, when the engine is run with D85E15ACN, there is an increase in brake thermal efficiency and reduction in hydrocarbon (HC), carbon monoxide (CO) and smoke emissions, compared to that of neat diesel.However, nitric oxide (NO) emission are more for D85E15ACN.
