A Simulation of Diesel Engine Combustion Noise 760552
In the present work, an attempt was made to predict engine noise from the shape of the burning rate curve. Thus, the influence of the shape of the burning rate curve on engine noise, especially on combustion noise was studied in detail and clarification of the relationship was successfully made.
At first, an approximation of burning rate curve using a function was attempted. And in second, the transfer rate from cylinder pressure to combustion noise was obtained.
Then, the relation between the deciding parameters of burning rate curve and noise and performance of engine were studied.
