Internal combustion engine with wedge-shaped cylinder head and integral intake manifold and rocker cover therefor

摘要

An internal combustion engine including an engine block having a pair of cylinder banks arranged in a V-shaped configuration such that each of the pair of cylinder banks presents a top wall disposed at an acute angle relative to the horizontal. Each cylinder bank includes a plurality of cylinders. A pair of cylinder heads are associated with each pair of cylinder banks. Each of the cylinder heads includes upper and lower walls disposed at an angle relative to each other such that each cylinder head is substantially wedge-shaped in cross-section. Each cylinder head is mounted to the engine block such that the upper wall of each cylinder head is substantially parallel to the horizontal. A pair of exhaust manifolds are mounted to each pair of cylinder heads. A single, integrated intake manifold and rocker cover is mounted to the horizontal upper wall of the pair of cylinder heads. The integrated manifold and rocker cover provide intake air to the cylinders in each of the pair of cylinder banks through the pair of cylinder heads and recirculates exhaust gas from the exhaust manifold to each of the cylinders in the pair of cylinder banks.
