Abstract

Priprema smjese goriva i zraka je zadaća uređaja za napajanje Ottovih motora gorivom. Pritom je bitno da se gorivo i zrak što potpunije izmiješaju i da se postigne što bolja homogenost smjese. L-jetronic sustav ubrizgavanja goriva radi s prekidajućim ubrizgavanjem u usisnu cijev ispred usisnih ventila. Glavne zadaće sustava su osigurati svakom cilindru toliko goriva koliko je potrebno za trenutačno stanje opterećenja motora pri korištenju vozila. Elektroničko upravljanje ubrizgavanja goriva omogućuje osnovnu i točnu regulaciju dodatnih količina goriva koju zahtijeva znatni broj različitih stanja opterećenja motora. Uvođenjem i razvojem L-jetronic sustava značajno je smanjeno zagađivanje okoliša zbog manje potrošnje goriva te su ostvareni mnogo čišći ispušni plinovi.

Abstract (english)

The preparation of fuel and air mixtures is the task of the Otto engine power supply. In doing so, it is essential that the fuel and air are mixed more thoroughly to achieve the best mix homogeneity. The L-jetronic fuel injection system works with intermittent injection into the suction pipe in front of the intake valves. The main tasks of the system are to provide each cylinder with as much fuel as it needs for the current engine load condition when using the vehicle. Electronic fuel injection control provides basic and accurate control of additional fuel quantities required by a number of different engine load states. The introduction and development of the L-jetronic system significantly reduced environmental pollution due to lower fuel consumption and much cleaner exhaust gases.
