Abstract
Paper presents an analysis of engine operating conditions in real traffic. Parameters used to characterization of engine operating conditions were collected by measurements for a urban type car with spark ignition engine which fulfill EURO 5. Measurements were performed in real traffic situations. Instantaneous vehicle velocity, rotational speed of engine and engine’s torque were recorded during car motion. In the next step the characteristic of engine operating conditions was formulated. It was made with assumption of equally part of urban, rural and highway types of motion. Finally the characteristic was compared with other one obtained on the base of test stand measurementsfor the NEDC driving cycle.
