Document Type and Number:
WIPO Patent Application WO/2024/069940
Kind Code:
A1
Abstract:
Disclosed is an air intake structure for an internal combustion engine having a plurality of cylinders 7, the air intake structure comprising an air intake passage 30 through which air is introduced from an air cleaner 106 into a combustion chamber 9, a fuel injection device 22 that supplies a fuel to the air intake passage 30, and a throttle valve 55 that adjusts the flow rate of the air introduced into the combustion chamber 9, wherein: the air intake structure has, downstream of the throttle valve 55, a tumble valve 57 and a plurality of air intake passages 31, 32 for generating a tumble flow; the air intake structure is provided with a resonator 45 by which the plurality of air intake passages 31, 32 communicate with one another, the resonator 45 being provided downstream of the tumble valve 57; and even when the resonator is provided to the internal combustion engine, which has a plurality of cylinders and in which a tumble flow is generated, the air intake structure makes it possible to suppress any increase in the size of the internal combustion engine without providing a resonator to each air intake port.
