Investigation on Combustion in Diesel Engines using a Constant Volume Combustion Chamber : Effect of initial Temperature

摘要: This paper presents some results or the experimental investigation on effect of initial temperature diesel combustion processes carried out in a constant volume chamber. The flollowing conclusions can be drawn from experiments : (1)The has an influence ignition delay, illumination pressure rise first flame formation, brightness and rate heat release. (2)As decreases, formation observed as dark luminous dots unique like twinkling stars found. (3)The empirical relationship between delay τi τid, p0, T0 oxygen concentration φ presented by following forms τi, τed ∝ p0 nφcexp(B/T0) .
