USER MANUAL FOR A COMPUTER PROGRAM TO SIMULATE THE DYNAMIC PERFORMANCE OF THE GENERAL MOTORS, MODEL 20-645E-4, DIESEL ENGINE-GENERATOR SET

摘要

This document describes a digital computer program developed to simulate an Electro-Motive Division (EMD), Model 20-645E-4, two-cycle, turbocharged, 2500 kw diesel engine-generator set manufactured by General Motors Corporation. This program has been used to simulate the performance of the engine-generator set during exposure to environmental and load transients. The model of diesel engine performance is sufficiently detailed to evaluate the thermodynamic state within each cylinder, in the inlet and exhaust manifolds, and at the entrance and exit of the turbocharger components at each instant of time. The pressure forces acting on each piston are translated through appropriate kinematic and dynamic relations to shaft output torque.
