SIMULATION OF BIODIESEL FUELLED COMPRESSION IGNITION ENGINE

Abstract

This project deals in Performance parameters and exhaust emissions of a diesel engine powered by diesel fuel and a biodiesels, namely Soybean oil methyl ester (SME) have been investigated using Diesel-RK engine simulation software. The performance of an engine whose basic design parameters are known can be predicted with the assistance of simulation programs into the less time, cost and near value of actual. Based on the DIESEL-RK software, an engine cycle simulation for a biodiesel fueled direct injection compression ignition engine was developed and used to study its performance and emission characteristics. The major objectives were to establish the engine model for simulation and then apply the model to study the biodiesel fueled engine and compare it to a diesel as well as biodiesel-fueled engine. The engine model used for carrying out experiments was single-cylinder Kirloskar make direct injection diesel engine. At selected engine operating conditions, sensitivities of engine performance and emission on engine load was investigated. Variations in cylinder pressure with bsfc, exhaust temperature, as well as emissions of nitrogen oxides, carbon monoxide, unburnt hydrocarbons were determined for both a biodiesel fueled engine and a conventional diesel fueled engine. Experimental result so obtained was compared with a thermodynamic analysis of the simulated engine to overall engine performance and emission characteristics.
