Abstract
Na performanse motora može se utjecati kutom početka izgaranja. Optimalan kut početka izgaranja je onaj u kojem će se dobiti najveća snaga motora uz najmanju specifičnu potrošnju goriva. Upravo ova problematika je obrađivana u ovom radu. Za četverotaktni atmosferski dizelski motor čija je izvedba slična motoru vozila VW Golf V 1,9 SDI, izvršeni su proračuni i analize različitih kutova početka izgaranja u programu Lotus Engine Simulation. Početni dio ovog rada zasniva se na razumijevanju dizelskog četverotaktnog motora, zatim slijedi tematika ubrizgavanja goriva, a potom izgaranje u dizelskom motoru. Zbog posebnosti dizelskog motora i njegovog načina izgaranja krucijalno je razumjeti svaki dio zasebno. Također, u radu je opisano modeliranje procesa izgaranja kao i Vibeova funkcija koja je temelj zakona izgaranja. Konačno, u radu su prikazani rezultati pri različitim brzinama vrtnje motora uz različite kutove početka izgaranja. Na temelju ove analize dan je optimalni kut početka izgaranja i prikazane su mogućnosti za poboljšanje karakteristika motora.
Abstract (english)
Engine performances could be influenced by the angle of the start of combustion. The optimal angle of the start of combustion is the one getting the biggest engine power with the lowest specific fuel consumption. This work has been dealing with these problems. Calculations and analyses of different angles have been done in Lotus Engine Simulation programme for four-stroke diesel engines which is similar to the VW Golf V1,9 SDI engine. The initial part of this work is dealing with the understanding of four-stroke engine, followed by the fuel injection, and diesel engine combustion. It is crucial to understand each part separately because of the specific characteristics of diesel engines and its way of combustion. Furthermore, this thesis explains the modelling of combustion processes as well as Vibe function which is the basis of combustion law. Finally, results for different engine speed revolutions with different angles of start of combustion have been presented in this thesis. In this thesis, optimal angle of start of combustion is determined as well as possibilities of improvement of overall engine performances.
