A quick and simple method of determining the cyclic variability of working process in internal combustion engines was introduced, that is, transient speed method, and its principle and actual applications were described. The transient speed was measured by dual sensors method, of which the structure and constitution were described and the measurement accuracy was analyzed. Two kinds of parameters to determine the cyclic variability were given. The results from transient speed were compared with those from cylinder pressure, which showed that it is simple and feasible to determine the cyclic variability of working process with transient speed.
