Abstract
An axial flow internal combustion engine comprises at least one cylinder (100), a piston assembly (110) within the cylinder defining a combustion chamber (200), wherein a fuel / air / oil mixture is compressed in one stroke of the piston assembly (110) in the combustion chamber (200), and a pump chamber (300) for sucking air drawn into the combustion chamber (200) in the above stroke of the piston assembly (110) for subsequent explosion of the fuel / air / oil mixture compressed in the combustion chamber (200). The piston assembly (110) comprises a piston head (111), a piston body (112), and a connecting rod (135) connected to the piston head (111) and having a cam follower (150) at one end (140) so as to abut against a surface (410) of a single power cam (400). The displacement of the piston assembly (110) within the cylinder (100) causes the cam follower (150) to roll on the surface (410) and rotate the power cam (400).
