Abstract

U ovom radu, detaljno su opisani i analizirani sustavi koji se najčešće koriste za ubrizgavanje goriva. Ti se sustavi ubrajaju u decentralizirano ubrizgavanje goriva kod Otto motora. Ti sustavi redom su: sustav za ubrizgavanje K - Jetronic, sustav za ubrizgavanje KE - Jetronic, sustav za ubrizgavanje Multi Point Injection (MPI), sustav za ubrizgavanje s mjerenjem volumnog protoka zraka (L - Jetronic), direktno ubrizgavanje (Gasoline Direct Injection - GDI). Osim toga u kratko je opisan razvoj benzinskih motornih vozila i sustava za ubrizgavanje, princip rada četverotaktnog Otto motora te analiziran cjelokupan sustav napajanja gorivom kod Otto motora. Osnovna zadaća svakog sustava ubrizgavanja je dobaviti gorivo iz spremnika, potom ga stlačiti na određeni tlak i fino raspršiti u prostor izgaranja u cilju postizanja potpunog izgaranja smjese. Da bi se ostvarilo potpuno izgaranje i pravilan rad motora, potrebno je međusobno uskladiti rad svih komponenti sustava ubrizgavanja kako ne bi došlo do kvara samog motora.

Abstract (english)

In this paper, the systems wich are commonly used for fuel injection are described and analyzed in detail. These systems are considered to be decentralized fuel injection with Otto engines. Those systems are: injection system K – Jetronic, KE – Jetronic, Multi Point Injection (MPI), directly injection (Gasoline Direct Injection - GDI) and injection system L - Jetronic. Besides that, development of gasoline engines and injection systems are briefly described, the principle of operation of the four-stroke Otto engine and analyzed entire fuel system of Otto engines. The main task of each injection system is to obtain fuel from the tank, then compact it on a certain pressure and finely disperse in the combustion space in order to achieve complete combustion of the mixture. To achieve complete combustion and proper operation of engine, it is necessary to synchronize the work of all components of the injection system to avoid malfunction of the motor itself.
