Application of Turbulent Combustion Model to a Spark Ignited L-Head Engine 910056
The developed k-ε-R model for computing the mean in-cylinder gas motions is being applied to a spark-ignited L-head engine of three different chamber designs. The theoretically calculated burned gas fraction is significantly affected by the flame front radius, the spark location and the squish area of the engines. The basic concept of the spherical flame kernel was employed in the early stage of flame development and later super-imposed with the in-cylinder gas motion to define the flame front radius. The calculated pressure rise was then compared with the measured pressure for its practicality in engine design.
