Modeling of a turbocharged SI engine
Turbo charged SI engines are a major possibility in the current trend of down-sized engines with preserved drivability performance. Considering control and supervision it is favorable to have a mean value model to be used e.g. in observer design. Such models of turbo engines are similar to those of naturally aspirated engines, but there are some special characteristics, e.g. the interconnected ...
متن کاملInjection Optimization for Heavy Duty Diesel Engine in Order to Find High Efficiency and Low NOx Engine Concept by Means of Quasi Dimensional Multi-Zone Spray Modeling
The purpose of this study is to investigate the effect of injection parameters on a heavy duty diesel engine performance and emission characteristics. In order to analyze the injection and spray characteristics of diesel fuel with employing high-pressure common-rail injection system, the injection characteristics such as injection delay, injection duration, injection rate, number of nozzle hole...
متن کاملdiesel engine simulation using a multi zone model and chemical kinetics mechanism
main purpose of current study is development of a new multi zone model for direct injection diesel engines. zone configuration is based on conical shape of spray. siebers’s correlation is used for spray cone angle calculation. experimental data are used for calculation of fuel inlet mass flow rate. fuel diffusion in different zones is calculated using fick’s law. a chemical kinetics mechanism c...
متن کاملTurbulent Flame Velocity Model for SI Engine
A new model for turbulent flame velocity of premixed flame in spark ignition engine for Iso-octane air mixture has been developed and validated for a wide range of engine operating parameters. The model developed is a zero dimensional thermodynamic model. The effects of engine speed (600-1160 rpm), equivalence ratio (0.7-1.1), unburnt mixture temperature (532650 Rankine), compression ratio (5-8...
متن کاملFuels With a High Enthalpy of Evaporation in Si Engine
The increasing use of fuels derived from oil, deepens concern about the fact that non-fossil fuels have to be considered as the fuels of the future. Among the alternatives, hydrogen produced from the abundant sources of water, seems to be one of the best, but it suffers drawbacks with regard to combustion, storage and transportation. The other alternatives are ammonia, produced from unlimited s...
