Estimation of Parameters for an Extremely Low Fuel Consumption Internal Combustion Engine-based Megameter-III Vehicle

摘要

Megameter-III is a special vehicle designed and constructed for udinternational competitions by our team. A crucial part of the vehicle is the udinternal combustion engine, which ought to have extremely low fuel udconsumption. The experiences of previous competitions confirmed that it is udnecessary to develop a professional telemetry system, which allows udtracking and logging online important parameters of the engine and the udvehicle. In this paper, we discuss results for estimating of several udparameters of the engine (angular velocity, angular acceleration, the udCoulomb-Morin external friction torque and the damping constant). In our udwork, injector-pulses and inductive sensor’s signals were monitored.
