Computer analysis results for a gasoline-fuelled SI engine indicate the peak temperature of 2887 K with mixture molar mass of 28.35 Kg/kmol. It is assumed that the combustion chamber end gases were burned at 5000 kPa by a steadily progressing flame. In knocking combustion, the end gases would abruptly auto-ignite and burn at essentially constant volume. The speed of sound in hot gases is given by c = (KRT) (1) (2) . The frequency of cylinder resonance is approximately f= c/ (2B). If the 4-cylinder, 2-litre engine used a "square" Bore/Stroke ratio, what knock resonance frequency would you expect for this engine? Assume a specific heat ratio k = 1.3 in your calculations.
