Abstract
Individual fuel injector performance deviations are determined with one of two in-chassis strategies for evaluating fuel injector performance, including a bare acceleration test and a loaded fuel injector performance test. In each of the tests, less than all of the engine cylinders are operated in a power mode. Individual fuel injector performance characteristics are extrapolated from at least one of engine response date and fuel injector response data from the tests.
