Abstract

This work is concciped with modeling and experimental validations of turbulent flame propagation in spark ignition engines. An existing engine cycle model, developed in leads for single chamber spark ignition engines, has been modified in order to obtain more realistic model predictions. The most significant improvement involved the incorporation of a sub-model for blow by and piston top land crevice flow.
To optimize and then verify the modified model predictions, the model was initially applied to data derived from experiments using an optically accessed two stroke spark ignition engine. The modified model was optimized an engine cycle at the running conditions compression ratio 8.3, equivalence ratio 1.0, engine speed 1100 rpm and intake manifold pressure of 0.85 bar. Thereafter, its predictive performance was verified for other cycles at varied engine operating conditions.
The inclusion of the blowby routine was shown to greatly improve the predictions of the model, compared with the experimental data. Inclusion of hlowby is particularly important is modelling ported two strake engines, due to the eefficiency of the piston rings early is the compression stroke.
