Performance optimization of Jatropha biodiesel engine model using Taguchi approach

Analysis of pollutant formation and control and fuel economy in diesel engines

A phenomenological combustion model for direct-injection, compression-ignition engines

Based on a multi-zone spray-mixing approach, an air-fuel mixing and combustion model for a Direct Injection Diesel engine is presented. The predictions from the model show very good agreement with the experimental data for various engines under a wide range of operating conditions. Major physical processes are modeled and validated independently. The atomisation process is based on Binary Drop Division concept. Fuel droplets are considered randomly distributed in the spray. A spherico-symmetrical transient drop evaporation model is used for evaporation calculation. A 3-dimensional spray-swirl interaction is modeled on centreline velocity vector/continuum approach. Turbulent mixing is characterised considering all possible available energy sources in DI diesel engines.

Model for predicting air-fuel mixing and combustion for direct injection diesel engine

This study focusses on the production of biodiesel from JCO through the transesterification process using a heterogeneous catalyst. Biodiesel produced has been blended with diesel in different prop...

Biodiesel production using heterogeneous catalyst, application of Taguchi robust design and response surface methodology to optimise diesel engine performance fuelled with Jatropha biodiesel blends

A mathematical model of an open-chamber diesel engine has been programmed for solution on a digital computer. The program incorporates an automatic procedure which, given the limits of design variables, will predict the values of these variables that will optimize engine performance. This technique can provide these results in a fraction of the time taken by parametric methods and provides a quick and efficient tool that can be used directly by the designer or the development engineer. Examples are given to demonstrate how the technique can be employed to maximize engine power to torque.
