A study of the combustion characteristics of indolene, methanol and indolene-methanol blends has been completed. The investigation included theoretical and experimental parts. In the theoretical part, turbulent burning velocity, laminar burning velocity, and mass burning velocity are computed. The experimental part was completed on a CFR spark ignition engine using indolene, methanol, and indolene-methanol blends. Methanol concentration was varied from 0 to 100 vol.%. For each blend, compression ratio was varied from 5.0 to KLCR (Knock Limited Compression Ratio). The results of theoretical analysis showed that the laminar burning velocity increased as the vol.% of methanol increased. The experimental results indicated that adding methanol to indolene, MBT (Minimum advanced for Best Torque) spark advance, volumetric efficiency, brake mean effective pressure are decreased while break specific fuel consumption, brake thermal efficiency an KLCR are increased. The theoretical and experimental results showed that adding methanol to indolene, apparent flame speed, turbulent burning velocity and the ratio of turbulent to laminar burning velocity increased. Pure methanol produced the highest turbulent burning velocity. It is concluded that methanol has considerable effect on the combustion characteristics of spark ignition engine.
