Computer Simulation of Effects on Air-Fuel Ratio of the Geometric Parameters of Carburetor's Main Metering System

Mathematic model for obtaining the performance of fuelling system of carburettor was established. Simulated calculation for obtaining the effects of changing structure parameters on air-fule ratio was proceeded. A large amount of saving of labour was obtained as compared with the experimental method. Results from the simulation will be able to provide the data for revising the margin tolerance of the parts maching. A proof test was proceeded through the prouducts exmamination at the Beijing Carburetter Plant.
