The Experimental Study on Combustion Instability in a CNG-CO2 Fuelled Engine

摘要：

An experimental research on combustion instability of a spark ignited single cylinder engine operating on CNG with 10％, 20％, 30％ and 40％ (in volume) CO2 enrichment was studied. The result shows that with the increase of CO2 in the fuel blends, the engine work stability decreases and the abnormal combustion phenomenon appear in order. With the analysis of the interdependence between the maximum cylinder pressure and the corresponding crank angle, the maximum cylinder pressure and the indicated mean effective pressure, the transformation pattern of characteristic parameters for both fast burning cycles and slow burning cycles is investigated. When the fraction of CO2 increases, the cyclic variation coefficient of indicated mean effective pressure increases, heat release rate becomes slower and the engine work stability decreases.
