Engine Power Test Code - Spark Ignition and Compression Ignition - As Installed Net Power Rating

2021-07-13
WIP
J1349
This standard is intended to provide a method to obtain repeatable measurements that accurately reflect true engine performance in customer service. Whenever there is an opportunity for interpretation of the standard, a good faith effort shall be made to obtain the engine’s typical in-service performance and avoid finding the best possible performance under the best possible conditions. Intentional biasing of engine component or assembly tolerances to optimize performance for this test is prohibited.

HISTORICAL
J1349_198306
This standard test code has been adopted by SAE to specify: (a) A laboratory engine dynamometer test procedure. (b) A basis for engine power rating. (c) A method for correcting observed power to standard inlet air conditions. The pressure and temperature correction formulas contained herein should be used only within the specified range of conditions (see paragraph 8.4.1) and are not intended for altitude derating.
