The article presents the results of research on the impact of operating conditions of the internal combustion engine of the Rosomak wheeled armored personnel carrier on fuel consumption in road conditions. Measurements were taken over a distance of several dozen kilometers while driving on road sections with different characteristics. The influence of standard operation and the engine’s overboost mode on the matrices of engine operating time share and fuel consumption was compared. Based on the obtained results, an analysis of the combat vehicle’s operating conditions was performed in terms of reducing fuel consumption.FUEL CONSUMPTION CHARACTERISTIC IN REAL ROAD OPERATING CONDITIONS OF COMBAT VEHICLES ENGINE
The paper presents the results of the investigations of the influence of the real road operating conditions of an armored modular vehicle (Rosomak) fitted with a diesel engine. Under the said conditions it is possible to obtain information on the actual vehicle fuel consumption. The tests were carried out on road portions of several kilometers each of different characteristics (urban cycle, extra urban cycle, combat cycle – combat simulation). The influence of standard operation and the operation in the overboost mode on the matrices of the time share of engine operation, fuel consumption have been compared as determined by the coordinates engine speed-load (or vehicle speed-acceleration) characterizing the dynamic engine or vehicle properties. Based on the obtained results an analysis of the operating conditions of the combat vehicle (and its engine) in the emission and fuel economy related aspect has been performed. (…)
