Gasoline engine development using LOGEengine
LOGEengine is an integrated simulation method for the prediction and optimization of engine in-cylinder performance parameters and studies of fuel effects on exhaust emissions. It contains a stochastic reactor model for 0D modelling (0d-SRM) with local effects in gas-phase space, direct fuel injection, temperature and species concentrations as random variables, detailed chemical kinetics, prediction of engine exhaust emissions (Soot, NOx, uHC), turbulence consideration via mixing modeling and self-calibration. LOGEengine can also model soot formation for diesel engines using detailed kinetic soot models, with gas phase chemistry, soot particle inception, condensation, coagulation, surface growth and oxidation. It can run equivalence ratio - Temperature (f-T ) diagnostics maps for analysis of regimes of emission formation in diesel engines using zero-dimensional methods with low CPU cost. It analyses local inhomogeneities in gas-phase space for species concentration and temperature due to mixing, fuel injection and heat transfer to cylinder walls, and their influence on soot and NOx formation from different fuels and in individual combustion cycles.
