Crossflow cylinder head

The cross-flow cylinder head is a design for cylinder heads of four-stroke engines, in which - opposed to the intake and exhaust manifold - in contrast to the counter-flow cylinder head.

For the manifolds can be as thick or Vierventilern two tubes are used and the intake is less exposed to the heat of the hot exhaust gases. Motors with cross-flow cylinder head do more and have a higher efficiency than engines where the intake and exhaust manifolds are on one side, but they can be accessible for maintenance and repairs worse. In addition, the width is usually greater.
