Abstract

Diesel engines used in agricultural machinery are gradually becoming one of the main emission sources causing air pollution. The reason is due to the rapid
increase in number but there is little change in technology as well as the application of measures to treat emissions. Recent studies show that the RCCI combustion
engine has outstanding advantages in reducing fuel consumption as well as Soot and NOx emissions in diesel engines using common rail fuel system. The content of
this paper will present the experimental results of agricultural machines diesel engines, converting from conventional mechanical fuel systems to using common rail
fuel systems using the RCCI combustion mechanism (RCCI). In RCCI, RON92 gasoline is selected as a Low Reactivity Fuel (LRF) injection on the intake pipe, diesel is used
as a High Reactivity Fuel (HRF) and directly injected into the combustion chamber. The results of the study showed that RCCI mode is effective in the area of average
load when the difference in fuel consumption compared to the original model is not significant. Meanwhile, Soot and NOx emissions are significantly reduced.
