COMPUTERIZED ENGINE TEST SYSTEMS FOR PERFORMANCE EVALUATION

A new engine development test system recently completed at one of the "Big 3" automobile companies handles performance testing in which horsepower, torque, mechanical efficiency and other engine design parameters are computer acquired. The configuration allows one processor and its interfaces to automatically control four independent test cells concurrently. Dynamometer reference speed, engine throttle position, spark advance and fuel rate are computer controlled, utilizing feedback to close the control loops. Optimization techniques are applied via Fortran algorithms to perform actuator control, achieving set point repeatability.
