Process of development of vehicles is nowadays preceded by extensive modelling tests, which allow evaluating influence of applicable design solutions on future utilitarian parameters of the vehicle. Here, estimation of vehicle's dynamics by measuring of acceleration time from 0 to 100 km/h can be an example. Similar, maximal speed, pollutants emission or fuel consumption under speciflc conditions of vehicle's operation can be the example. Modelling research allow to shorten time of introduction of new vehicle for production significantly. Most eager group of model used in simulation tests of vehicles, according to short time of calculation, is black box models. They do not take into consideration they cyclic type of operation, however, it is possible to identify fast and simple their coefficients. This work involves description of reciprocating engine tests, which have been done under transient and steady-state conditions. Transient conditions were forced by rapid change of engine control signal. During the tests differences of torque generated by engine under transient and steady-state conditions have been registered for the same control signal. Basing on the received results a new algorithm of transient torque calculation has been proposed. In the presented model value of the transient torque has been combined with the engine control signal and others engine parameters, which deser ibe transient history of the engine. Hence, iterative procedures of the transient torque calculation with declared time step have been implemented.
