Abstract
An engine cylinder block assembly for a V-type engine wherein inner walls of the cylinder banks define a relatively oil free valley which is closed by a rigid valley cover to provide additional stiffness to the inside walls of the blocks, thereby stiffening the block against vibration and bending. The valley cover also includes sealed pockets for enclosing knock sensors mounted upon upwardly extending bosses in the bottom of the valley to both protect the knock sensors and permit their removal without requiring removal of the valley cover from the engine cylinder block. Oil entrainment due to pulsing air flows between crank chambers of the engine are reduced by providing openings in the valley floor between the front and rear crank chambers of the engine while the adjacent inner crank chambers are separated from direct connection with the valley.
