Prediction and Measurement of Fluid Flow in Single Cylinder Engine Carburetors

A mathematical model has been developed to analyze fluid flow in carburetors of single-cylinder engines. Single and multi-phase flow are modeled for steady-state-cyclic and transient conditions. This provides insight to design parameter interactions not adequately analyzed with steady-state techniques. The model predicts pressures and flow rates by utilizing an implicit finite-difference solution of one-dimensional equations of conservation of mass and momentum. Example applications and experimental verification are provided.
