Experimentation is conducted on an IDI diesel engine and the results of combustion and vibration on IDI -Diesel engine fueled with the preheated Jatropha Methyl Ester (JME) are presented. The Present research trend is to replace conventional diesel by renewable alternative fuels in view of fast depletion of petroleum reserves and to reduce the exhaust emissions from the engines without altering...

One of the important problems in reducing of pollutant emission from DI and IDI diesel engines is trade-off  between soot and NOx. Split injection is one of the most powerful tools that makes the chance to shift the trade-off curve closer to origin.  At the present work, the effect of split injection on the combustion process and emissions of a cylinder IDI diesel engine under the specification...

A 3-D CFD model based on KIVA 3 code is developed with a “reduced” detailed chemical kinetics of 291 elementary reaction steps with 79 chemical species for diesel fuel combustion. The model was validated by the corresponding experimental results and employed to examine some important parameters which have significant effects on the engine performance for an IDI diesel engine with a swirl chambe...

The combustion processes and emission formation in pre and main chambers of a Lister 8.1 IDI diesel are simulated with the Computational Fluid Dynamics (CFD) code. The model includes spray atomization, mixture formation and distribution and subsequently the combustion processes and emissions formation modeling are carried out with considering of flow configurations in two chambers. A part load ...

in this study a heat exchanger is designed for cooling exhaust gas and an experiment is carried out to investigate the effect of exhaust gas recirculation (egr) temperature on destruction of the fuel’s availability due to combustion processes in idi diesel engine cylinder. to serve this aim an exergy analysis is conducted on the engine cylinder which provides all the availability terms by which...
