Based on the two different designs of combustion chambers shown in Fig. P9.2, answer the following questions: (a) when combustion chamber design is changed from A to B, explain whether combustion rate will be faster, slower, or about the same rate. Justify your answer. (b) Which combustion chamber requires higher octane number fuel? If both engines are running on the same fuel, which engine can be operated at a higher compression ratio? Justify your answers.
