Intake manifold having negative pressure relief |
摘要 |
Disclosed is an intake manifold having a surge tank connected to an air intake passage for air to be supplied to an internal combustion engine. The intake manifold includes a gas introduction section communicated to the air intake passage or the surge tank for introducing gas containing fuel component to the surge tank and a negative pressure feed passage communicated to a portion of the air intake passage or the surge tank which portion is upstream of the gas introduction section in the movement direction of the air and configured to feed a negative pressure inside the surge tank to the outside. The negative pressure feed passage is connected to the air intake passage or the surge tank via an expansion chamber having a larger cross-sectional area than the cross-sectional area of the negative pressure feed passage. |
