STUDY AND TEST TO CONFIRM AUTOMOBILE DRIVETRAIN COMPONENTS TO IMPROVE FUEL ECONOMY. VOLUME II. THE DRIVETRAIN DESIGN PROCESS WITH AN AUTOMATIC TRANSMISSION

This report presents the key thought processes that are used by the drivetrain designer in matching an engine to a given vehicle with specific performance goals in mind. This report provides those uninitiated in this aspect of automotive design valuable insight into the compromises that must be made between acceleration, gradeability and top speed. This report also presents a method by which the performance of any modern torque converter may be approximated with accuracy once only the stall torque ratio and diameter are known. These two parameters can be used to generate torque converter maps that almost duplicate actual maps for torque converters of any modern manufacturer, and greatly facilitate computer simulation.
