In order to explore the combustion performance of premixed charge induced ignition for dual fuel engine, an experiment was undertaken on CY25TQ diesel engine to investigate the combustion and emission characteristics by changing the compression ratio. Experimental results show that under the condition of 1200 r/min, when the compression ratio is reduced from 16.9 to 15.4, and the premixed charge induced ignition leading to the start of combustion reaches the maximum delay to 1.5°CA ATDC, the biggest drops of maximum pressure, maximum pressure rise rate and peak of instantaneous heat release rate reach 52, 47 and 29% respectively. But the effective thermal efficiency declines 24%.
