Opis:: 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.

Opis:: In earlier designs, the compression-ignition engine units were controlled by means of mechanical elements. They were levers, rods, springs, pawls, cams and others. The quality of such control did not ensure the required repeatability of control parameters in the fuel injection and combustion process. After the introduction of the standards limiting engine emissions of the limited exhaust components, the aforementioned engine control systems were not able to meet the requirements. The mechanical regulation of mechanical systems has been replaced by electronic control systems. It was the development of computer techniques and software that enabled design solutions of control systems for injection and combustion process parameters in engines with sufficient accuracy and repeatability of test results. The modern EDC (Electronic Diesel Control) control system, due to the computing power of microprocessors increased in recent years, enables meeting high requirements of modern Common Rail injection systems. The article presents issues in the area of four thematic levels: the design and modernization of the engine, its operation, diagnostic problems in order to determine reasons of unit failures and bench-top methods for assessing the effectiveness of unit repairs as well as issues concerning alternative fuels.
