An internal combustion engine including at least one engine cylinder, the cylinder includes a cylinder cavity with first and second cylinder heads which are interconnected by a cylinder wall, the cylinder further includes a piston member which is slidably movement within the cylinder cavity and between a first and a second extreme position intermediate between the first and second cylinder heads, the piston member partitions the cavity into a first and a second combustion chambers which are in alternate combustion when in normal engine operation. This engine cylinder configuration substantially increases the usable cylinder volume to enhance efficiency and reduces the weight to power ratio.
