Sažetak
The purpose of the research is to experimentally examine possibilities of using compressed natural gas in conventional dual- fuel internal combustion engine, with goals that include achieving maximum efficiency and maintaining exhaust gas emissions on permitted levels. Special attention was given to the improvement of characteristics at low and high loads, where dual-fuel shows some disadvantages compared to the normal diesel operation. By using the fully flexible fuel injection system and exhaust gas recirculation, there were achieved different combustion techniques including: diffusion flame combustion, premixed flame propagation and premixed chemically controlled combustion of homogeneous or stratified mixture. It is shown that adequate injection strategies in combination with other operating parameters can significantly improve exhaust gas emissions from dual-fuel engine.
