<p style="text-align: justify;">U radu je razvijen jedan matematički model za simuliranje ponašanja nekih važnih radnih parametara motora SUS, kada u njegovom usisnom sistemu postoje neispravnosti tipa: „nepredviđeni ulaz vazduha u usisni kolektor“, „pogrešno očitavanje senzora masenog protoka vazduha“, „pogrešno očitavanje senzora pritiska u usisnom kolektoru“, „pogrešno očitavanje senzora temperature u usisnom kolektoru“ i „umanjen EGR protok“. Na osnovu rezultata ovog modela predložen je novi dijagnostički koncept, u okviru kojeg je razvijen jedan model za prepoznavanje pomenutih neispravnosti. Predloženi koncept je proveren na realnim podacima, prikupljenim ispitivanjem jednog stvarnog motora u laboratorijskim uslovima, pri čemu su dobijeni zadovoljavajući rezultati.</p> / <p>A mathematical model capable of simulating some important IC engine operating parameters behavior when a fault in its intake air path exists. The faults considered are of the following types: „air leakage in the intake path“, „faulty mass air flow sensor“, „faulty manifold absolute pressure sensor“, „faulty intake air temperature sensor“ and „clogged EGR pipe“. Relying on the data obtained by the fault simulator, a novel diagnosis concept is proposed. A model for fault detection and diagnosis was developed in the scope of the concept. The proposed concept was tested on the real data collected from an automobile IC engine in the laboratory conditions and satisfying results were obtained.</p>
