Abstract
Official abstract text for this publication.
The internal combustion engine includes an oil storage portion in which a suction portion of oil supplied to various parts of the internal combustion engine body is disposed, an oil channel through which the bubble-containing oil returned from the various parts of the internal combustion engine body to the oil storage portion flows, and a high pressure portion in which the oil is supplied and becomes higher than the atmospheric pressure, and an oil injection hole for injecting oil toward the bubble-containing oil flowing in the oil channel is provided.
First claim
Opening claim text (preview).
What is claimed is: 1 . An internal combustion engine comprising: an oil storage portion in which a suction portion is disposed, the suction portion being a portion that sucks oil to be supplied to various parts of an internal combustion engine body; an oil channel through which bubble-containing oil to be returned from the various parts of the internal combustion engine body to the oil storage portion flows; and a high pressure portion that has a higher pressure than an atmospheric pressure and to which the oil is supplied, the high pressure portion being provided with an oil injection hole through which the oil is injected toward the bubble-containing oil flowing through the oil channel wherein the high pressure portion is an oil discharge channel to which the oil sucked up by an oil pump via the suction portion is discharged, and the oil injection hole is provided in the oil discharge channel. 2 . The internal combustion engine according to claim 1 , wherein the high pressure portion is a balancer housing chamber in which a balancer of a balancer device is housed, and the oil injection hole is provided in a housing that constitutes the balancer housing chamber. 3 . The internal combustion engine according to claim 2 , wherein a drive unit that rotates a balancer shaft of the balancer device is housed in a drive unit housing chamber that is provided as a separate space different from the balancer housing chamber. 4 . The internal combustion engine according to claim 1 , wherein the oil channel includes a tilted surface along which the bubble-containing oil to be returned to the oil storage portion flows down, and the oil is injected from the oil injection hole toward the tilted surface.
