ABSTRACT:
An RPM variation test for use in an engine analyzer system is used to test internal combustion engines. The engine analyzer individually disables cylinders and monitors instantaneous engine RPM, to generate an engine map. The engine analyzer performs an engine performance test upon the internal combustion engine. The engine map is used to map the results of the engine performance test. Using the present invention, an engine map is produced just prior to performing an engine performance test.
