Abstract

This paper is to carry out a numerical simulation of combustion characteristics for a closed cycle diesel engine (CCDE) with different intake gas contents under different engine speeds and equivalence ratios. The numerical simulation used Kiva3V-Release2 code as the main program by modifying some subroutines containing different intake gas contents of oxygen, argon, and nitrogen and their thermodynamic properties. The results show that the pressure will increase earlier if the percentage of argon is higher when we use argon to replace nitrogen, and the ignition delay will be shorter, too. The higher in-cylinder temperature results from a higher concentration of argon.
