Smoothly start.Afterwards with the continuous operating of engine, the thermal energy for release of burning can be more and more, entire engine and start
The temperature on machine periphery can constantly rise, and the ice being jammed in charge air cooler fin is made also gradually to melt with continuous rise of temperature
Change, charge air cooler recovers unimpeded.Gas from inlet manifold air inlet enters through charge air cooler in inlet manifold housing again, and
It is discharged through inlet manifold gas outlet, and indoor negative pressure of burning also constantly reduces, when the negative pressure that the bottom in seal spool portion is subject to
When being not enough to compression camber of spring, under the resilient force of spring, seal spool portion fits together again with bonnet.
Compared with prior art, the utility model has the characteristics that：
1) by-pass collar is integrated in inlet manifold, the parallel relationship with charge air cooler is formed, when charge air cooler is because of low temperature knot
When ice blocks, allow gas to enough through by-pass collar enter in engine combustion room, ensure the normal startup of engine, work as charge air cooler
After recovering normal work, by-pass collar just keeps normally off, thus the normal startup and stable operation of automobile has been effectively ensured,
Securely and reliably；
2) by-pass collar is compact-sized, occupies little space, easy to process and assembling；
3) by-pass collar, and energy can be laid at multiple positions respectively in inlet manifold according to the needs of intake uniformity
Enough by changing the spring ratio of spring and the forced area of spool, the unlatching threshold value of by-pass collar is adjusted, flexibility is good, should
It is wide with scope.
