This document specifies the procedure to be used for a manufacturer to certify the net power and torque rating of a production engine according to SAE J1349 (Rev. 8/04) or the gross engine power of a production engine according to SAE J1995. Manufacturers who advertise their engine power and torque ratings as Certified to SAE J1349 or SAE J1995 shall follow this procedure. Certification of engine power and torque to SAE J1349 or SAE J1995 is voluntary, however, this power certification process is mandatory for those advertising power ratings as “Certified to SAE J1349” or “Certified to SAE J1995.” In the event that an engine made by one manufacturer is sold to a consumer in a vehicle produced by a second manufacturer, engine certification may be completed by either manufacturer or by both manufacturers working together.

J1826
The test procedures outlined in this SAE Recommended Practice are applicable to single rotor turbochargers having either fixed- or variable- geometry with the following caveat: At this stage in the development of variable-geometry (VG) turbochargers, it would be impractice to generate a detailed practice to cover all types of VG turbochargers which may evolve. However, there is a requirements to quote performance data within a stipulated degree of accuracy and to furnish comprehensive performance information. This will form a basis for this document where further refinements may be added as experience and necessity dictate.

The purpose of this document is to provide a recommended laboratory test procedure and presentation format for establishing the component performance for a turbocharger. It is intended that this test procedure be used to determine turbocharger compressor and turbine performance characteristics.

J1995_201401
This SAE Standard has been adopted to provide a basis for dynamometer determination of gross engine power and torque under reference conditions. It is intended for use primarily by engine manufacturers who supply engines for installation by others in applications where the engine manufacturer may not control the induction and exhaust system design or the speed at which the engine is run.

J1349_201109
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.

This SAE Recommended Practice has been developed to provide a uniform method for reporting the weight, dimensions, center of gravity, and moment of inertia of internal combustion engines. SAE J2038 is not intended to cover the technical interface between the engine and transmission. To locate the rear of the engine crankshaft in relationship to the rear of the flywheel housing, refer to SAE J617.

J1312
The purpose of this SAE Standard is to provide a standardized test procedure for generating engine performance maps in order to facilitate data reporting and data comparisons. An engine performance map is a listing of engine specific fuel consumption, specific exhaust emissions and other variables obtained at specific engine speeds and loads. Engine performance maps as specified by this code are primarily used in the light duty vehicle industry and can be used in fuel economy simulation programs. This document is applicable to both four-stroke spark-ignition (SI) and compression-ignition (CI) engines, naturally aspirated and pressure charged, with or without charge air cooling. The large number of control variables available on modern engines results in large flexibility in calibration, and it is frequently necessary to run part-load maps to explore the relative merits of different control strategies.

J2723_200708
This document specifies the procedure to be used for a manufacturer to certify the net power and torque rating of a production engine according to SAE J1349 (Rev. 8/04) or the gross engine power of a production engine according to SAE J1995. Manufacturers who advertise their engine power and torque ratings as Certified to SAE J1349 or SAE J1995 shall follow this procedure. Certification of engine power and torque to SAE J1349 or SAE J1995 is voluntary, however, this power certification process is mandatory for those advertising power ratings as “Certified to SAE J1349”. In the event that an engine made by one manufacturer is sold to a consumer in a vehicle produced by a second manufacturer, engine certification may be completed by either manufacturer or by both manufacturers working together. An example of the latter would be the completion of witness testing by the engine manufacturer with the submission of certification documents by the vehicle manufacturer.
