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 sufficient. The
amount of NO emission in the end of closed cycle simulation was found equal 674.875 ppm and In cylinder
pressure versus engine crank angle degree was simulated that maximum value found in 366 oCA that equal
to 27.3222 bar.
