Analysis of Modern Engine Control Units at Road Vehicles

Suvremene upravljačke jedinice motora kod cestovnih vozila jedne su od glavnih komponenata motora. U posljednja dva desetljeća, upravljačke jedinice motora značajno su se razvile, ali još uvijek su u procesu napredovanja. Upravo zbog tog velikog napretka, omogućile su i puno efikasniji rad motora, nadzor većine podsustava automobila, nižu potrošnju goriva, ali i nižu emisiju štetnih tvari iz ispušnih plinova. Bitno je naglasiti kako je uz napredak upravljačkih jedinica motora, neizbježan bio i razvoj senzora za slanje informacija i upravljanje motorom. Ovaj rad također se dotaknuo područja dijagnostike pogrešaka i kvarova kod automobila te njihovog načina otklanjanja.Modern engine control units at road vehicles are one of the main components of engine. In the last two decade, engine control units have had great development and they are still developing. Exactly because of that, engine control units enabled more efficient engine operation, subsystem monitoring, lower fuel consumption and lower emission of pollutants from exhaust gases. It is important to point up that beside the development of engine control units, inevitable was the development of sensors for sending information and engine control. This work also mentioned the error diagnosis areas and engine failures and their ways of eliminating them
