Özet:

 

Considering the energy crises and pollution problems today,  investigations have concentrated on decreasing fuel consumption by  using renewable alternative fuels and on lowering the concentration of  toxic components in combustion products.  A simulative model for  establishing the performance parameters of spark ignition engines  fueled with a range of fuels (gasoline, ethanol, or hydrogen) and  their mixture is presented.  The incidence of pre-ignition and its  relative intensity as well as cyclic variations are also accounted  for.  The 2-zone incorporates a procedure for deriving an estimate of  the effective duration of combustion and the associated mass burning  rate for various operating conditions and fuels.  A system of  first-order ordinary differential equations was obtained for the  pressure, mass, volume, temperature of the burned and unburned gases,  heat transfer from the burned and unburned zone, mass flow into and  out of crevices, and the composition of combustion products.  The  mathematical and simulation model has been developed, tested, and  verified against the experimental data to simulate a 4-stroke cycle of  a spark ignition engine fueled with gasoline, ethanol, or hydrogen as  a single fuel or their mixture.  The results obtained from the present  study have shown the capability of the model to predict satisfactorily  the performance and emissions including the incidence of pre-ignition  at various engine-operating conditions.  A good agreement was obtained  between the results of the present model and the experimental results.
