Abstract

Sustav napajanja gorivom kod motora s unutarnjim izgaranjem namijenjen je da se pomoću njega dobije smjesa potrebna za sagorijevanje, koja se sastoji od goriva pohranjenog u spremniku i atmosferskog zraka, s time da se oboje moraju dovesti u cilindar motora. Otto motori koriste laka benzinska goriva, dok diesel motori koriste teška dizelska goriva, stoga postoje velike razlike u sustavima za napajanje gorivom između Otto i diesel motora. Otto motori mogu koristiti direktno ubrizgavanje goriva,... More gdje se gorivo izravno isporučuje u komoru za izgaranje, ili indirektno ubrizgavanje, gdje se gorivo miješa sa zrakom prije usisnog takta.Od 1980. pa nadalje, rasplinjače kod Otto motora zamijenili su sustavi ubrizgavanja. Osnovna razlika između rasplinjača i sustava ubrizgavanja goriva je da se kod ubrizgavanja gorivo raspršuje kroz male mlaznice pod visokim tlakom, dok se rasplinjač bazira na usisavanju vanjskog zraka ubrzanog kroz Venturijevu cijev te tako pomoću struje zraka uvlači gorivo.

Abstract (english)

The fuel system of an internal combustion Engine is intended to producea combustible mixture composed of the fuel stored in the fuel tank andatmospheric air, and then deliver both to the cylinders. Petrol engine uselight grade gasoline fuel while the Diesel Engines utilize heavy dieselfuel, therefore fuel supply systems and their differ greatly in petrol anddiesel engine. Petrol engines can use gasoline direct injection, where the fuel is directly delivered into the combustion chamber, or... More indirect injection where the fuel is mixed with air before the intake stroke.On petrol engines, fuel injection replaced carburators from the 1980s onward. The primary difference between carburetors and fuel injection is that fuel injection atomizes the fuel through a small nozzle under high pressure, while a carburetor relies on suction created by intake air accelerated through a Venturi tube to draw the fuel into the airstream.
