In this study, the effect of EGR(exhaust gas recirculation) on the combustion and emissions characteristics has been investigated using a compression ignition (CI) engine operated with LPG(liquefied petroleum gas) and cetane enhancing additive; Di-tertiary-butyl peroxide(DTBP) while fixing the quantity of fuel injection. Increasing the EGR rate leads to deteriorate the IMEP(indicated mean effective pressure) and increase the ignition delay. As a results, use of high EGR rates at constant boost pressure is a way to drastically reduce nitrogen oxides(NOx) but with an moderate increase of indicated specific fuel consumption(ISFC) and other emissions (CO and hydrocarbon).
