ABSTRACT:
An internal combustion engine including an engine block having a top wall and a plurality of longitudinally aligned, spaced cylinders. A cylinder head has upper and lower walls with side walls extending therebetween. The cylinder head is mounted to the engine block with the lower walls sealingly opposing the top wall of the block so as to close the open ends of the cylinders. The cylinder head includes at least four passages associated with each of the cylinders extending through the cylinder head for delivering intake air to the associated cylinder and for removing exhaust gas from the associated cylinder. Each of these passages include an inlet, an outlet in fluid communication with the associated cylinder and a flow path extending therebetween. At least one of these passages includes a boss which is recessed in the passage and aligned with the inlet and which is adapted to receive a fastener employed to clamp the cylinder head to the engine block.
