Internal combustion engine with a cross-flow cylinder head, especially an air-cooled detached cylinder head for motor cycle internal combustion engines

摘要

In an internal combustion engine with a cross-flow cylinder head, especially an air-cooled detached cylinder head for motor cycle internal combustion engines, with a control shaft for valves controlling inlet and exhaust ports and a scavenging direction SR essentially averaged over the course of the inlet and exhaust ports in the cross-flow cylinder head, it is proposed, in order to obtain a well-cooled valve arrangement with a relatively rigid valve gear, that the inlet and exhaust valves be arranged in planes essentially parallel to the scavenging direction and that the control shaft be drive-connected to rocker arms, assigned to the valves, by way of tappets arranged in the cross-flow cylinder head. <IMAGE>
