Download or read book SAE 1999-08-0382, Dynamic Modeling and Simulation of Diesel Engine Starting Process written by Jung-Kyu Park and published by . This book was released on 1999 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: To optimize the cold-start process of a 4-stroke, 8-cylinder diesel engine, a dynamic simulation model from cranking to idle speed is developed. Physically based first-order nonlinear differential equations and some algebraic equations describing engine dynamics and starter motor dynamics are used to model the performance of cold-starting process which is very complex and many components including the cold-start-aiding method are involved. These equations are solved using numerical schemes to describe the starting process of diesel engine and to study the effects of cold-starting parameters. The validity of this model is examined by cold-start test at -20°C. This model can be served as a tool for computer-aided control systems designed to improve cold-start performance.
