ABSTRACT:
A head gasket, for sealing a junction between a top face of a cylinder block of an engine and a bottom face of a cylinder head thereof, of the type having a row of relatively large circular cut-outs, that, in use, correspond in size, number and position to that of cylinder spaces formed in the cylinder block and a plurality of apertures that are relatively small in comparison to the circular cut-outs that, in use, correspond in number and position to coolant passages formed in the faces of the cylinder block and cylinder head, as well as holes sized and positioned, in use, in accordance with holes in the cylinder block and head for connecting bolts and holes for lubricant circulation. In addition to a first row of apertures extending along a first lateral side of the circular cylinder cut-outs, the gasket is provided with a second row of apertures that are used to orifice outlet coolant passages from the cylinder head to the cylinder block. The second row of apertures comprises pairs of apertures flanking longitudinally opposite sides of each of the circular cylinder cut-outs, an aperture of each pair being larger in area than the other aperture of each pair. Furthermore, from a point between an intermediate pair of the circular cylinder cut-outs, the larger apertures and the smaller apertures, respectively, on each of opposite sides of the intermediate point, progressively increase and decrease in area toward opposite ends of the second row of apertures. The gasket is also provided with a third row of smaller orificing apertures, as well.
