31.Turbocharging tends to reduce fuel consumption because the friction losses of the turbocharged engine do not increase as fast as the increase in power output, and because the improved charging results in better combustion conditions. Based on this description, which is the correct statement?
(A)The friction losses of the turbocharged engine are beneficial for reducing fuel consumption.
(B)The better combustion conditions resulted from the improved charging are beneficial for reducing fuel consumption.
(C)The friction losses of the turbocharged engine are beneficial for better combustion conditions.
(D)The increased friction losses of the turbocharged engine are beneficial for better combustion condition.

渦輪增壓機目的降低燃油消耗率因為增壓機的摩擦損失並不如主機功率輸出增加的如此快速,然後改善空氣過給造成更好的爆發燃燒條件.基於這些敘述,哪一種說明正確？
Ａ.過給增壓柴油機的摩擦損失對降低燃燒消耗率有益＝＝>錯誤
Ｂ.較佳的爆發狀況是由改善進、掃氣過給使燃燒消耗率降低所造成 ＝＝>正確
C.過給增壓柴油機的摩擦損失對爆發狀況有益
Ｄ.增加過給增壓柴油機的摩擦損失對爆發狀況有益
