Abstract
An internal combustion engine construction to improve thermodynamic efficiency by providing, in addition to the standard cylinders and pistons, a supplemental cylinder connected to each combustion chamber of each cylinder and, a piston in each supplemental cylinder associated to move in conjunction with the standard pistons, the relationship of the association being such that the volume of the combustion chamber can be enlarged or ensmalled either by a manual control or an automatic control regulable in response to engine conditions and to modify the volume time relationship.
