摘要
The concept of a highly premixed dual fuel triple-direct-injection (TDI) combustion model aimed at providing adjustable in-cylinder stratified charge from two distinctive fuels, ethanol and diesel fuels, is presented. The charge reactivity of RON 80 (80 research motor octane number), RON 85, and RON 90 is explored in the present study. The outcomes of the experiment clearly indicate that at RON 80, a high indicated thermal efficiency of about 47% and low mono-nitrogen oxide (NOX) emissions of less than 2.6 g kW(-1) h(-1) were achieved. The behavior resembled diffusion-limited combustion for late injection of (SOImain = -10 and -12 degrees CA ATDC) for RON 90 and (SOImain = -8 and -9 degrees CA ATDC) for RON 85. The combustion regime approximated the premixed combustion characteristics for varied (SOImain) timings with high reactive charge RON 80. The higher charge reactivity combustion outperforms low reactivity charge, delivering a 3% improvement in indicated thermal efficiency over low reactivity charge operation.
