Abstract

Dual fuel operation using different reactive fuels have been examined. The present study conducted experiments in a single cylinder compression ignition engine. N-heptane (octane No.=0) and i-octane (octane No.=100) were injected through two different injectors set at intake port and cylinder head, respectively. By comparing a case (A) in which n-heptane was directly injected into premixed charge of i-octane with a case (B) in which n-heptane was premixed and i-octane was injected into the n-heptane mixture, and by widely changing injection quantity ratio and direct injection timing, the effects of mixture concentration and combustion phasing on emissions and engine performance including thermal efficiency and maximum pressure rise rate were investigated.
