ABSTRACT:
A method for the analysis of performance characteristics of a vehicle includes the measuring of a plurality of performance variables over the course of a predefined test protocol, typically providing for the variation of operating parameters during the duration of the test. Each variable is compared to an appropriate reference at a chosen number of points or "test sites" during the test, and the results of each comparison is classified as being above, below or within tolerance. The comparison results are tabulated into a value matrix. The matrix is compared to a series of reference matrices, each of which is associated to a different cause, such as bad timing, fouled spark plug, poor cylinder compression, and the like. Association of the values in the matrix to a reference matrix allows the problem as reflected by the measured performance variable values to be identified.
