Abstract
A four stroke internal combustion engine (10) having a V-type configuration with eight cylinders (11). The firing order of the cylinders is such that a relatively balanced mechanical operation occurs. A right manifold (16) and a left manifold (18) connect to the right bank (12) and left bank (14) respectively. Each of the manifolds (16, 18) includes first and second primary runner. For the right bank (12), the first primary runner (22) connects to one cylinder and the second primary runner (24) connects to the other three cylinders. The separate primary runners (22, 24) are configured such that no two cylinders within a given primary runner will begin to exhaust within 180 of each other. The left bank is similarly configured. In this way, interference of exhaust pulses between cylinders is avoided, leading to equal cylinder to cylinder operation with less back pressure, while still using minimal space around the engine.
