Reciprocating piston internal combustion engine
Abstract
A reciprocating piston internal combustion engine is described which consists of: a piston movably disposed within an engine cylinder, the piston having a top surface and a piston ring, the engine cylinder and the top surface of the piston defining a combustion chamber, the piston having first and second sections which are divided by a vertical plane containing an axis of a piston pin, the first section being formed with a major thrust surface and the second section being formed with a minor thrust surface; and means for thrusting the piston against a major thrust side wall of the cylinder before the piston reaches top dead center in the cylinder, the thrusting means comprising: means defining a space in the piston, the space communicating with the combustion chamber and being located in the piston second section; a movable member disposed within the space, the movable member being capable of being thrust in the direction of a minor thrust side wall of the cylinder by gas pressure within the combustion chamber and being arranged to thrust the piston ring against the minor thrust side wall when thrust by the gas pressure; and means for producing gas pressure within the combustion chambermore »
