Operation of car engines definitely shows varied values of parameters such as crankshaft speed or load. This paper presents the research and results on load and crankshaft speed in a compression ignition engine. Therefore, the research focused on an operation of a passenger car under urban and non-urban conditions. Our NI Diadem Analysis-based research referred to the data acquired by an OBD-II system. The results obtained enabled some layered charts to depict a frequency of operating states as specified by engine load and speed as well as histograms of these parameters in individual rides. Our investigation showed that operating conditions have an impact on engine operating states. In urban conditions, our engine operated within the range of 700-2000 rpm but idle was more than 50% of the time and load in most cases was not higher than 20%. In non-urban conditions, our engine operated within the range from 700 to 3000 rpm and load was up to 70%.
