Mathematical modeling of bioethanol fueled DI diesel engine

Abstract

In the present scenario, the energy security and environmental issues are matter of concern for every nation. The discovery of a new ecofriendly renewable fuel source is extremely important to overcome this problem. Biofuels mainly biodiesel and bioethanol are gaining importance as an alternative fuel for transportation sector due to their biodegradable and renewable nature. Bioethanol can be explored from different feed stock such as sugar, starch and waste material. It is an oxygenated fuel and able to reduce both NOx and particulate matters in large amount. So it is a good alternative fuel for CI engine. In this project, a zero dimensional, quasi steady diesel engine simulation model is developed to prove the bioethanol as a fuel for diesel engine. By using modern analysis and simulation tool like MATLAB we can drastically decrease the need for experiment and hence save a lot of time and money. Thus by taking some assumptions and applying basic thermodynamic properties a model to predict the pressure and volume variation in the cylinder of the CI engine with the given fuel has been developed in this project.
