COMPUTER SIMULATION OF THE GM UNIT INJECTOR

Descriptions of both a complex and a simplified version of the mathematical model of GM's fuel injector are presented, along with a model for linkage dynamics simulation. The models include a new and self-consistent development of the injection pressure and flow equations. Experimental verification of this simulation demonstrates the model's adequacy.
