Abstract
An engine includes a cylinder block including a first jacket through which a coolant flows, a spacer disposed within the first jacket, a cylinder head including a second jacket through which the coolant flows from the first jacket; and a gasket interposed between the cylinder block and the cylinder head. The cylinder block includes a branch passage branched off from the first jacket to supply the coolant to an external device. The gasket includes communication ports that communicate the first jacket with the second jacket. The spacer includes a protruding portion that penetrates one of the communication ports that is closest to the branch passage. There is a clearance between the protruding portion and the one of the communication ports.
