Performance and Emission Formation Evaluation of a Diesel-Fueled Free Piston Engine using CFD
Konferensbidrag (offentliggjort, men ej förlagsutgivet), 2006

The KIVA-3V code coupled with detailed chemistry was used to evaluate a two-stroke compression ignited free piston engine designed for electric power generation. A comprehensive chemical kinetics mechanism for a diesel oil surrogate was used to simulate efficient low-emission engine operation in the conventional diesel and HCCI-like combustion modes. The formation and destruction of chemical species in the cycle and the effects of varying the start of injection on the exhaust mixture composition and combustion / indicated efficiencies have been investigated. In order to help analyze the emissions a special approach based on the parametric temperature-equivalence ratio maps has been used.
