Abstract
This paper presents an analytical method of simulating an automotive engine lubrication system. It charts oil flow rates and distribution in a typical V-8 engine; this is followed with a detailed analysis of major components. Basic hydraulic diagrams and the lubrication circuit analysis are described with working equations. The computer program with sample results is illustrated, and the calculations are compared with actual dynamometer test results. This analytical method can be used to determine the adequacy of oil pump capacity, and to evaluate bearing design and oil path circuitry.
