QUALITY CONTROL OF EXHAUST AT OTTO ENGINES

U ovom radu je opisan proces kontrole ispušnih plinova u Otto motorima prilikom pregleda vozila na tehničkom pregledu.U uvodnom dijelu rada je opisan proces i kontrola ubrizgavanja goriva u Otto motor opremljen jednostavnim sustavima ubrizgavanja rasplinjačima, koji nisu opremljeni uređajima za pročišćavanje ispušnih plinova (katalizatori). Nadalje je opisan proces ubrizgavanja goriva u Otto motor opremljen složenijim sustavima ubrizgavanja i uređajima za pročišćavanje ispušnih plinova (katalizatori) čijim radom upravljaju računala, koja preko kontrolnih senzora vrše kontrolu i korekciju ubrizgavanja goriva u Otto motor. I na kraju su prikazani rezultati kvalitete ispušnih plinova kod Otto motora sa i bez uređaja za pročišćavanje ispušnih plinova (katalizatora), te njihov utjecaj na okoliš.This paper describes the process of exhaust gas control in Otto engines when inspecting vehicles for technical inspection.The following section describes the process and control of fuel injection into an Otto engine equipped with simple carburettor injection systems, which are not equipped with exhaust gas purification devices (catalytic converters). In following describes the process of injection fuel into an Otto engine equipped with more complex injection systems and exhaust gas purification devices (catalysts) operated by computers, which control and correct the injection of fuel into the Otto engine through control sensors. Finally, the results of the exhaust gas quality the Otto engines with and without the exhaust gas catalyst and their environmental impact are presented
