| Abstract: | A geometric model of combustion chamber for gasoline engines is proposed on the basis of spherical trigonometry. The model can be used to calculate the flame propagation in the combustion chamber. By using this model, the flame area and burnt volume in relation to the flame front were calculated for the cubic combustion chamber and for the combustion chamber of the CA6102 gasoline engine. The results prove that the model is effective. |
