Abstract
Although the relationship between luminous intensity of radicals and equivalence ratio φ has been investigated, the previous works underestimates an influence of high combustion pressure. The experiment was conducted by applying different initial charge pressure in the constant volume chamber and by changing φ. The result obtained indicates clearly that the luminous intensity for both CH, C2, and OH radical changes increases exponentially as the combustion pressure increases regardless of φ. Therefore each radical intensity can be approximated as a function of combustion pressure. It shows that luminous intensity of C2 radical is strongly influenced by the value of φ than that of CH, OH radical, especially in lean mixture state. It is verified that the measurement of φ can be accomplished using the ratio of luminous intensity of CH and C2 radical, and combustion pressure. The value of φ was estimated and compared with the actual value; the accuracy was about ±5%.
