    • An intake air heating apparatus may include an air pump, an intake chamber, an air heater, and a delivery pipe associated with an intake manifold. When intake air is heated, a throttle valve may be closed, the air pump may be started, and electrical power may be supplied to the air heater. The air flowing from the intake chamber may be heated by the air heater. Thereafter, the air may flow from the delivery pipe into branch pipes and circulate to the intake chamber. At that time, since the throttle valve may be closed, and an intake valve or an exhaust valve of an engine may be closed, the heated air may not flow out and the air temperature in the intake manifold and the intake air heating apparatus may increase.
    • 进气加热装置可以包括空气泵,进气室,空气加热器和与进气歧管相关联的输送管。 当进气被加热时,可以关闭节流阀,可以启动空气泵,并且可以向空气加热器供电。 从进气室流出的空气可以被空气加热器加热。 此后,空气可以从输送管流入分支管并循环到进气室。 此时,由于可以关闭节流阀,并且发动机的进气门或排气阀可能关闭,所以加热的空气不会流出,并且进气歧管和进气加热装置中的空气温度可能增加 。

    • A fuel injection method wherein optimum fuel injection timing in a fuel-injection type gas fuel engine is determined by setting fuel injection end timing to be after the start of opening of an intake valve. That is, when injection ends in a first half of the intake valve open period the volumetric efficiency .eta.v falls and the engine output also falls, because the injection period overlaps with a period of positive pressure arising inside the intake pipe before opening of the intake valve, but when injection ends in a second half of the intake valve open period the volumetric efficiency .eta.v rises and the engine efficiency also rises, because the injection period overlaps with a period of negative pressure arising in the intake pipe during the first half of the intake value open period. Consequently, when fuel is injected during this trough in the intake port pressure, the volumetric efficiency increases and the engine output also increases by several percent.
    • 一种燃料喷射方法,其中燃料喷射型气体燃料发动机中的最佳燃料喷射正时通过将燃料喷射结束定时设定为在开阀开始之后。 也就是说,当进气阀打开期间的前半部分的喷射结束时,体积效率等级下降,并且发动机输出也下降,因为喷射周期与在进气口打开之前在进气管内部产生的正压时间重叠 但是当喷射在进气阀打开时段的后半段结束时,容积效率η升高并且发动机效率也上升,因为喷射周期与进气管在上半年期间产生的负压时间重叠 摄入量开放期。 因此,当在进气口压力期间在该槽内喷射燃料时,容积效率增加,发动机输出也增加了几个百分点。
