Abstract
An application of computer controlled fuel injection systems in vehicle engines and growing demands concerning toxic substances emission and fuel consumption was a main reason for OBD (On Board Diagnosis) development. In spite of a great technological development, only some tractors are equipped in diagnostic systems. On board diagnosis is strongly connected with emission demands and does not concern other important vehicle functions.In the developed mechatronic diagnostic system, based on generated consequences, four groups of defects are accepted: functional (uf), which inhibit performance, exhaust (ue), which causes increase toxic emissions, that jeopardize driving safety (us) and defects that affect engine performance (ud). The diagnostic system consists of a board computer with specialized programs, acquisition data modules working in CAN net with protocol DeviceNet, measuring sensors and actuators. In the paper accepted assumptions, a structure of mechatronic system model and organization of a diagnostic program are presented.
