This paper describes a floating cylinder internal combustion engine. It comprises: a slidable having an intake port and an exhaust port; a reentrant cylinder head connected to a cylinder block, the cylinder block having an intake passage and an exhaust passage communicating with the intake port and the exhaust port respectively, the intake passage and the exhaust passage formed in the cylinder block having a longitudinal dimension with respect to the cylinder axis of grater length than a longitudinal dimension with respect to the cylinder axis of the intake port and the exhaust port, the cylinder slidably positioned inside the cylinder block, the cylinder having a top portion slidably positioned within an annular recess between the reentrant cylinder head and the cylinder block; a piston slidably positioned within the cylinder, and a port timing control means interactive with the cylinder for adjusting a position of the intake port and the exhaust port during movement of the piston with respect to the longitudinal dimension of the intake passage and the exhaust passage, the port timing control means causing the cylinder to move independently with respect to the movement of the piston within the cylinder.
