Claims9
An internal combustion engine, comprising a plurality of cylinders;
- two pistons located in each of said cylinders and forming two combustion chambers with the latter;
- and two output shafts, each of said cylinders having two windows through which said two pistons of each of said cylinders are connected with said two output shafts, each of said pistons being connected to both output shafts.
An internal combustion engine, comprising a plurality of cylinders;
- two output shafts;
- and two pistons located in each of said cylinders and forming two combustion chambers with the latter, said two pistons of each of said cylinders being movable relative to one another in a direction perpendicular to a plane extending through axes of rotation of said two output shafts.
An internal combustion engine, comprising a plurality of cylinders;
- two pistons located in each of said cylinders and forming two combustion chambers with the latter;
- and a third immovable piston located between said first two pistons and forming with the latter two additional combustion chambers.
An internal combustion engine, comprising a plurality of cylinders;
- and two pistons located in each of said cylinders and forming two combustion chambers with the latter, one of said pistons in each of said cylinders being movable, while another of said pistons in the same cylinder is immovable.
An internal combustion engine, comprising a plurality of cylinders;
- two pistons located in each of said cylinders and forming two combustion chambers with the latter;
- and two output shafts turnable by said pistons and having axes of rotation, said pistons having centers of gravity which are located at opposite sides of a plane extending through said axes of rotation and spaced at equal distance from said plane.
