This paper describes an engine laboratory where rationalization and automation are developed to a comparatively high level. Function test beds are arranged mainly for accurate measurements and flexible conditions. Endurance test beds feature flexible programed cycling, automatic data recording, and test control. All test beds include extensive arrangements for automatic handling of emergency situations with maximum safety for test engines and equipment. Endurance test beds simulate road conditions and show considerable savings in test time and running cost as compared with vehicle testing. Examples of correlation between road testing and statistics from equipment reliability are also presented.
