The ignition delay associated with fuels of low ignition quality results in a late and more explosive start to the combustion period, which results in higher peak pressures and consequent rough and noisy operation. Therefore, ______ .

Athe ignition delay could increase the mean effective pressure of cycle
Bthe more explosive start to the combustion period due to ignition delay could generate the higher peak pressure正確答案
Cthe ignition delay associated with fuels of low ignition quality is beneficial for engine performance as it results in higher peak pressures
Dthe ignition delay associated with fuels of low ignition quality could alleviate the noise generation
答案與詳解
B
正確答案
發火延遲導致燃燒爆炸性增加,進而產生更高峰值壓力與運轉噪音。

為什麼答案是 B

完全符合題幹邏輯,發火延遲導致燃燒具爆炸性,進而產生更高的峰值壓力(higher peak pressures)。
