Macroscopic spray characteristics of next-generation bio-derived diesel fuels in comparison to mineral diesel

Appropriation of bio - diesel blends in diesel engine

Performance And Emission Characteristics Of Direct Injection Diesel Engine Using Bio-Diesel With Scr Technology

In this study, the biodiesel produced from cottonseed oil was prepared by a method of Transesterification and its blends of 25%, 50%, 75% and 100% in volume, and standard diesel fuel separately. The effects of biodiesel addition to diesel fuel on the performance, emissions and combustion characteristics of a naturally aspirated DI compression ignition engine were examined. Biodiesel has differe...

Performance and Emission Characteristics of a Slow Speed Diesel Engine Fueled With Soybean Bio Diesel

Fossil fuels have given us utility and continued their role in a variety of areas, but rapid depletion of these fossil fuels directs the researchers to find alternative fuels for the present energy crisis. In this perspective a Bio-diesel came in to existence which meets the present energy demand and emission norms. Biodiesel is a non–toxic, biodegradable and renewable alternative fuel that can...

Diesel Spray Modelling: A Review

An overview is provided of the current state of the art in Diesel spray prediction. The modelling of the key physical processes is discussed and the impact on prediction accuracy is illustrated by way of examples. The overall conclusions are that comprehensive methodology of useful accuracy now exists; but further theoretical and experimental research is needed, especially in respect of atomisa...

prediction of ignition delay period in d.i diesel engines

a semi-empirical mathematical model for predicting physical part of ignition delay period in the combustion of direct - injection diesel engines with swirl is developed . this model based on a single droplet evaporation model . the governing equations , namely , equations of droplet motion , heat and mass transfer were solved simultaneously using a rung-kutta step by step unmerical method . the...
