A free piston internal combustion engine has at least a motor cylinder formed with intake and exhaust ports and a driving piston reciprocating in said cylinder and cooperating with the exhaust ports. Air delivery means are formed in the cylinder for supplying air originating from a compression cylinder associated with the motor cylinder as a jet directed along the driving piston, towards the head ring of the latter to prevent overheating. The cylinder may additionally be provided with a circuit for circulating a coolant.
