The purpose of present paper is simulation a direct injection stratified charge natural gas engine. The KIVA-3V code was used for gaseous fuel injection simulation. Compression and expansion stroke of engine cycle is simulated using KIVA-3V code. In cylinder fuel equivalence ratio distribution criterion is used for studying mesh independency. The results show that 550000 cells number is suff...

In all over the world the demand of energy is increasing day by day and fossil fuels are depleting at a very fast rate, therefore to fulfill the energy demand of the world there is a need to find out an alternative fuel and in this depleting fossil fuel era Biodiesel is one of the best available energy source to overcome the world’s energy demand. There is a long list of shrubs, trees, and herb...

For numerical prediction of the NOX in the exhaust of a compression ignition engine a model was developed by considering the parameter equivalence ratio. This model was validated by comparing the predicted results of NOX with experimental ones. The ultimate aim of the work was to access the applicability, robustness and performance of the improved NOX model against other NOX models. Keywords—Bi...
