Abstract
U ovom je radu dan literaturni pregled procesa izgaranja u Otto i dizel motorima. Istaknuto je da termodinamički proračun daje sastav produkata izgaranja pri određenom tlaku i temperaturi. Ravnotežni sastav produkata izgaranja sastoji se od malih molekula kao CO2, H2O, CO itd., te slobodnih radikala, primjerice ⋅OH. Ipak, zbog kratkog vremena miješanja smjese zraka i goriva, isparavanja goriva i zapaljenja, složene kinetike kemijskih reakcija, te konačne brzine procesa prijenosa tvari i energije u cilindru motora, dolazi do nepotpunog izgaranja i nastanka čvrstih lebdećih čestica. Sastav nastalih čvrstih čestica u području veličina od svega nekoliko mikrometara, te nastanak značajne količine čestica u području nanometarskih veličina, čini ih posebice štetnima po ljudsko zdravlje. Stoga je predložena tehnologija elektrostatskih filtera/taložnika za učinkovito pročišćavanje plinova izgaranja.
Abstract (english)
In this work, a literature survey of combustion processes occuring in Otto and diesel engines had been given. It is pointed out that thermodynamic calculations give final combustion products equilibrium composition at particular pressure and temperature. Equilibrium composition at high temperatures consists of small molecules like CO2, H2O, CO... and free radicals like ⋅OH etc. However, due to the short time of air/fuel mixing, fuel evaporation and ignition, complex reaction kinetics and finite rates of heat and mass transfer processes in motor cylinder, gives rise to incomplete combustion and formation of particulate matter. Composition of paticulate matter formed and its particle size distribution in micrometer and submicrometer range makes them particularly harmfull for human health. Thus, a electrostatic precipitator technology is proposed for efficient flue gasses cleaning.
