Cross-flow cylinder head

from Wikipedia, the free encyclopedia

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

This means that thicker pipes or, in the case of four-valve engines, two pipes can be used for the manifolds, and the intake system is not as exposed to the heat of the hot exhaust gases. Cross-flow cylinder head engines perform better and are more efficient than engines that have the intake and exhaust manifolds on one side, but they may be less accessible for service and repairs. In addition, the overall width is usually larger.
