摘要：
PROBLEM TO BE SOLVED: To inhibit reduction of supercharging pressure while dropping intake air temperature in an engine with a supercharger.
SOLUTION: Pressure of air near a connection point of a branched channel 20 is rapidly reduced by opening a branched channel valve 22 connecting an intake air passage 8 and an pressure accumulation tank 21. Negative pressure wave which is local minimum section of intake pressure pulsating in connection with this is made to reach a combustion chamber 2 during valve open period of an intake valve 11. Intake air temperature can be dropped by reduction of intake air pressure. Since reduction of supercharging pressure is inhibited during the valve close when valve open and valve close of the branched channel valve 22 are executed at least one time each during one combustion cycle, reduction of supercharging pressure can be inhibited as a whole.

要解决的问题：在增压器的发动机中降低进气温度的同时抑制增压压力的降低。 解决方案：通过打开连接进气通道8和压力蓄积池21的分支通道阀22，快速地减少分支通道20的连接点附近的空气压力。作为进气的局部最小部分的负压波 在进气门11的阀打开期间，与此相关的压力脉动进入燃烧室2.通过降低进气压力可以降低进气温度。 由于在一个燃烧循环期间至少一次执行分支通道阀22的阀打开和阀关闭时，在阀关闭期间抑制增压压力的降低，因此整体上可以抑制增压压力的降低。 版权所有（C）2010，JPO＆INPIT
