Abstract
An axial cylinder internal combustion engine having a cylindrical cam is provided with special cam roller followers subjected to oil under pressure to keep them in close operating contact with the radial cam surfaces. Oil pressure is also used to maintain the pistons in contact with the circumferential cam surface. The engine further includes a rotary valve for supplying a stratified charge to each cylinder and unique means for continuously lubricating the valve face.
