This work presents a carburetor model written in FORTRAN and coded into a user routine object in a one-dimensional engine software program, GT-Power. The model was compared to experimental data from a single cylinder, carbureted, spark ignition, gasoline, air cooled engine.
The model, which the user subroutine was coupled with, was the GT-Power model created and calibrated for the engine tested. The model gave an error of less than 15 percent compared with measured engine performance. When the user routine object was connected, the results compared between the GT-Power model and the experimental data showed good agreement of 20 percent error or less for the wide open throttle case.
