Methanol has been regarded as a potential transportation fuel due to its advanced combustion characteristics and flexible source. However, it is suffering from misfire and high HC emissions problems under cold start and low load conditions either on methanol SI engine or on methanol/diesel dual fuel engine. Hydrogen is a potential addition that can enhance the combustion of methanol due to its high flammability and combustion stability. In the current work, the effect of hydrogen ratio on the laminar flame characteristics of hydrogen-methanol-air mixture under varied equivalence ratios was investigated on a constant volume combustion chamber system coupled with a schlieren setup. A high-speed camera, set at 512X512 pixel and 10000 fps, was used to record the instantaneous images of the flame front during propagating. Experiments were performed over a wide range of equivalence ratios of the premixed charge, varied from 0.8 to 1.4, as well as different hydrogen ratios, 0%, 5%, 10%, 15% and 20% (n/n). All tests were carried out at fixed temperature and pressure of 400K and 0.1Mp. The results showed that for a fixed hydrogen fraction, the laminar burning velocities first increase and then decrease as the equivalence ratios increasing. Meanwhile, the flame stability improved with the increase of equivalence ratios. Laminar burning velocities were improved drastically due to the addition of hydrogen. It was also identified that as a consequence of gradually increasing the proportion of hydrogen to total input fuel, the flame instability timing advanced. A detailed discussion on the differences between various equivalence ratios and hydrogen ratios for hydrogen-methanol-air mixture combustion in terms of combustion characteristics has been presented.
