The paper presents the results of the research on the uniqueness of the combustion process in the Perkins 1104D-E44TA engine already equipped with a Common Rail injection system, and then adapted on an engine test stand to dual-fuel operation. The result of the combustion process is an indicator diagram. The combustion process in the cylinder of the tested engine was evaluated by determining
the uniqueness indicators of subsequent operating cycles, such as: the uniqueness indicator for the maximum pressure of the operating cycle, the uniqueness indicator for the mean indicated pressure, the uniqueness indicator for the indicated diagram and the uniqueness indicator for the partial indicator diagram. The conducted tests and the analysis of the results showed the impact of dual-fuel power
supply of the tested engine on the combustion process, as compared to supplying the engine only with diesel fuel, for which it has been optimized.
