An engine with a slider-crank mechanism, comprising a housing, containing a shaft with a crank, and at least two cylinders with pistons mounted on rods, the ends of which extend from the pistons through guide bushings of the cylinders and are connected to one another by means of a yoke assembly. A housing of the yoke assembly is configured in the form of a frame having a rectangular cross-section and inner guiding surfaces for a block slider mounted with freedom of movement between said surfaces and with freedom of rotation on the crank of the shaft. The block slider is comprised of two connected halves with grooves for lubricating an outer sliding surface. The housing of the yoke assembly is mounted such that its lateral surfaces are disposed between guiding surfaces inside the engine housing.

The present invention is directed to a process for operating a combustion engine having a double-sided piston in a piston cylinder, wherein every stroke of the double-sided piston is a power stroke. Every piston cylinder defines a combustion chamber on each side of the double-sided piston. The process includes igniting a fuel-air mixture in each combustion chamber on each side of double-sided piston during every compression, i.e., at about top dead center and at about bottom dead center. The process utilizes the double-sided piston to achieve two power strokes per piston for each engine cycle.

An internal combustion engine comprising at least one cylinder and a pair of opposed, reciprocating pistons within the cylinder forming a combustion chamber therebetween. The engine has at least one combustion igniter associated with the cylinder, a portion of the combustion igniter being exposed within the combustion chamber formed between the opposed pistons.

The disclosure relates to an internal combustion engine (1) with at least one double cylinder (2), in which two inner pistons (6) and two outer pistons (7) are arranged such that they reciprocate in the double cylinder (2) by at least one respective inner connecting rod (8) or a respective first outer connecting rod (11a) and a respective second outer connecting rod (11b) with the aid of a crankshaft (4). The present disclosure provides an internal combustion engine (1) in which the outer connecting rods do not pivot. The two first outer connecting rods (11a) of the two outer pistons (7) are coaxial and integrally formed; and the two second outer connecting rods (11b) are coaxial and integrally formed.

An internal combustion engine using a two stroke cycle includes a pair of opposing cylinder units, each of which are located on opposing sides of a crankcase. In each cylinder unit is a cylinder with a piston disposed in the cylinder. Each piston is coupled to a piston rod that is aligned along an axis that passes through the center of each cylinder bore. The piston rods pass through the crankcase wall into the crankcase chamber, and are further coupled to a yoke. Each cylinder unit has an intake channel from the crankcase chamber to a cylinder intake port in the cylinder. As the piston traverses its upstroke in its cylinder, it creates a vacuum under the piston. At the top of its stroke a piston intake port becomes aligned with the cylinder intake port, allow fuel to be drawn into the cylinder under the piston. As a result, a continuous vacuum is experienced in the crankcase without the need for mechanical valving arrangements.
