The effects of equivalence ratio on combustion and emissions characteristics were investigated in a compression ignition engine using simulated-EGR by diesel fuel. In order to analyze the effects of simulated exhaust gas recirculation, as a diluent almost pure carbon dioxide gas was supplied to reduce oxygen concentration at a surge tank. For investigating the effects of simulated-EGR on the combustion and emissions characteristics, the combustion characteristics for the variation of equivalence ratio were measured and analyzed in a single-cylinder diesel engine with a compression ratio of 17.3 and a displacement volume of 373.3cc. With the exhaust emission characteristics, nitrogen oxides (NOX), carbon monoxide (CO) and hydrocarbon (HC) were measured by exhaust gas analyzer under the various simulated-EGR ratios.
The experimental results show that maximum IMEP was measured at BTDC 5° and the IMEP was gradually reduced as advanced injection timing. NOX emissions decreased dramatically with the increase of equivalence ratio and it was almost not produced at the range from 0.8 to 1.0 of equivalence ratio.
