Abstract:
1. A cylinder head for sealing at least two cylinders of an internal combustion engine, the cylinder head defining a first intake passage for supplying air through a first intake valve opening to a first cylinder of the at least two cylinders, the first intake passage extending to the first intake valve opening from an intake face of the cylinder head and being disposed for fluid communication, at the intake face, with a first intake runner of a mating intake manifold; the cylinder head defining a second intake passage for supplying air through a second intake valve opening to a second cylinder of the at least two cylinders, the second intake passage extending to the second intake valve opening from the intake face and being disposed for fluid communication, at the intake face, with a second intake runner of the mating intake manifold; the cylinder head defining an exhaust vent at an exhaust face of the cylinder head; the cylinder head defining a first exhaust passage for conveying a first stream of exhaust gas to the exhaust vent from a first exhaust valve opening associated with the first cylinder; the cylinder head defining a second exhaust passage for conveying a second stream of exhaust gas to the exhaust vent from a second exhaust valve opening associated with the second cylinder; the exhaust vent being disposed between the first cylinder and the second cylinder; the first exhaust valve opening being disposed outboard of the first intake valve opening; and the second exhaust valve opening being disposed outboard of the second intake valve opening; wherein the first cylinder is adjacent to the second cylinder and the first intake valve opening and the second intake valve opening are disposed approximately equidistant from a central plane defined between the first cylinder and the second cylinder and centrally through the exhaust vent.
