Engine Power Test Code - Spark Ignition and Compression Ignition - Gross Power and Torque Rating
J1995
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.
Rationale: The Engine Power Test Code Committee will review this standard to insure it is still accurate and appropriate since it has been 7 years since this standard was last updated. I am the Test Lab Manager at Kohler, where this test code is used on a weekly basis.
Regarding expected changes, fuels have changed recently which may lead to updates to Tables 5 and 6. Further, the Engine Power Test Code Committee is reviewing J1349 (net power) and any changes to that standard will likely need to also change in this gross power standard.
