ABSTRACT:
A coolant groove-type internal combustion engine has a cylinder block that includes a frame having at least one longitudinal surface and a lateral member transverse to the longitudinal surface, the lateral member defining a coolant passage therethrough, wherein the lateral member also defines at least one cylinder opening and a groove coolant port extending from the coolant passage to the cylinder opening. A cylinder liner includes a cylindrical member, defining an elongated cylinder bore. The cylinder member has an outer surface that has a diameter that allows the cylindrical member to be fitted into the cylinder opening so as to form a coolant jacket between the outer surface of the cylindrical member and the longitudinal surface. The outer surface of the cylindrical member includes an upper portion that plugs the groove coolant port.
