Abstract

 This paper explores the possibility of utilizing ethanol-diesel emulsion in different numeric values refer to the percentage of ethanol in DI Diesel engine.The main aim of the present review is to study the effect of performance and emissions overall of the blends can be minimized moderately, even total hydrocarbon emissions are fewer than those of emission characteristics of emulsified fuels on a DI diesel engine. The ethanol diesel emulsion decreases the brake thermal efficiency, brake torque, and brake power while increase the brake specific fuel consumption. At high loads, the emulsion minimize smoke significantly with a small penalty on CO, acetaldehyde and unburned ethanol emissions compared to diesel fuel. NOx and CO2 emissions of the blends are reduced fairly. At low loads, the emulsion have small effects on smoke reduction due to leaner mixture. With the aid of additive ignition improver, CO, unburned ethanol and acetaldehyde diesel fuel. The results indicate the performance and emission characteristics are studied and compared with the base fuel.
