11.因燃油品質不良，需採取串聯式淨油系統，下列何者排列順序最為適當？ (A)沉澱櫃→預熱器→潔油機→淨油機→日用櫃 (B) 沉澱櫃→預熱器→淨油機→潔油機→日用櫃 (C)預熱器→日用櫃→淨油機→沉澱櫃→潔油機 (D)潔油機→淨油機→沉澱櫃→預熱器→日用櫃

30.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,＿＿＿＿＿＿＿ . (A)the ignition delay could increase the mean effective pressure of cycle (B) the more explosive start to the combustion period due to ignition delay could generate the higher peak pressure (C)the ignition delay associated with fuels of low ignition quality is beneficial for engine performance as it results in higher peak pressures (D)the ignition delay associated with fuels of low ignition quality could alleviate the noise generation
