    A.reduce engine horsepower output

    B.aid in silencing the exhaust noise

    C.increase the mean effective pressure

    D.contribute to effective cylinder scavenging

  • 第2题:

    If fuel injection to a four-stroke/cycle diesel engine begins earlier than designed, ignition may be delayed because the

    A.cylinder compression pressure may not be high enough

    B.cylinder compression temperature may be too high

    C.fuel oil injection pressure may not be high enough

    D.scavenge and purge process is incomplete


    正确答案:A

  • 第3题:

    The firemen were unable to control the blaze.

    A:flower
    B:blow
    C:flame
    D:stroke

    答案:C
    解析:
    本题考查的是对名词的认知。这句话的意思是:消防队员无法控制住大火。blaze的意思是“大火”,例如:The fire burned slowly at first , but soon burst into a blaze.这场火起初烧得很慢,但不久就成了熊熊烈火。选项A flower花、最好或最精致的部分。选项B blow打击。选项C flame火舌、火苗、火焰,例如:The whole city was in flames.全城都着火了。选项D stroke一击。blaze和flame意思最接近,所以选C。
