COMBUSTION MODELING OF GASOLINE TWO-STROKE LINEAR ENGINE BY THE MODIFIED WEIBE FUNCTION

Tulus et al.

Abstract


This paper presents the mathematical modeling of combustion in a two-stroke
linear combustion engine incorporating combustion and kickback
chambers. A thermodynamics simulation is performed using a Weibe
flrnction that applied to linear engine. The computer program is
developed to compute the instantaneous velocity and temperature in the
combustion chamber. The fuel is gasoline and the cylinder bore sizes to
be considered are of 50mm and 76mm. From the computation, the
results show that the peak temperatures are 870 K and 995 K, the mean
velocities during expansion are 3.8m/s and 5m/s, the mean velocities
during compression 2.9m/s and 4.4m/s, respectively.
