A multi-dimensional computational fluid dynamics (CFD) modeling was conducted on a direct injection turbo-charged diesel engine based on KIVA-4 code under full and mid engine loads. Multi-component fuel evaporation model of KIVA-4 was used and coupled with advanced combustion chemistry to...

Recently some studies have been carried out on RCCI (reactivity controlled compression ignition) engines; however, they routinely used the “one factor at a time” approach, which may neglect interactions among the manipulated factors. This paper reports the use of a more effective approach...

A multi-dimensional computational fluid dynamics (CFD) modeling was conducted on a D.I. (Direct Injection) diesel engine fueled by bio-diesel based on KIVA4 code. Comprehensive chemistry prediction of bio-diesel fuel was taken into account by enhancing the combustion model of the default KIVA4...

A numerical modeling study was performed to investigate the impacts of biodiesel blend ratio on the emission formation processes of a diesel engine. Simulations were conducted using 3-D CFD simulation software KIVA4 coupled with CHEMKIN II. The integrated chemical kinetics with 69 species and...

In the present study, effects of hydrogen induction on combustion characteristics of a compression ignition diesel engine were investigated and a comprehensive model for identifying knocking combustion was developed. This was done by defining number of critical local regions within the CFD...
