Abstract
First and second oil chambers arranged in a cylinder arrangement direction with a partition wall interposed therebetween are formed in a cylinder block. A cylinder head includes first and second communication passages respectively connected to the first and second oil chambers. The communication passages are configured so that a resistance generated when gas is caused to flow from the first oil chamber to a space above the head through the first communication passage is smaller than a resistance generated when gas is caused to flow from the second oil chamber to the space above the head through the second communication passage. The cylinder block includes an oil passage connected to both the oil chambers. The partition wall includes a connection hole for allowing the first and second oil chambers to communicate with each other.
