Problems solved by technology

Internal combustion engines employing sliding reciprocating pistons and chambers and utilizing connecting rods to convert the reciprocating motion into rotational output have the problem of losing some of the combustion energy due to friction between the piston cylinder and connecting rod and crankshaft

Embodiment Construction

[0047] figure 1In the illustration, an internal combustion engine arrangement 10 includes an engine block 12 defining cylinders 14 . A piston 16 is slidably disposed within the cylinder 14 and an impeller assembly 18 is disposed at one end of the cylinder 14 .

[0048] Although the engine block 12 is shown with relatively thin walls for clarity, the cylinders 14 are formed in the engine block in a known manner and may have relatively thin walls. figure 1 Thicker walls shown in .

[0049] The cylinder 14 is elongated and has an axis A. As shown in FIG. The cross section of the cylinder 14 perpendicular to the longitudinal axis is circular. Four beads 20 project inwardly from the inner wall of the cylinder 14 , extending parallel to the longitudinal axis A of the cylinder 14 . The weld beads 20 are evenly spaced from each other at an angle of 90 degrees, such as figure 2 shown. A fuel injection port 22 is provided on the sidewall of the cylinder 14 , the port receives fue...

Abstract

An internal combustion engine (10) includes an engine block (12) defining a cylinder (14) having a longitudinal axis A. A piston (16) is slidably disposed within the cylinder (14), and an impeller (18) is disposed at one end of the cylinder (14). The impeller (18) is rotatably mounted on a shaft (30) extending out of the cylinder (14) and driven in rotation by the rotation of the impeller (18). The engine further includes an anti-rotation structure (20) to prevent the piston from rotating around the longitudinal axis of the cylinder, and an impeller vane (38) arranged on the surface of the piston, facing the end of the cylinder where the impeller is arranged. The combustion gas produced by the fuel combustion between the piston and the impeller in the cylinder swirls through the action of the swirling blades, and the swirling combustion gas then makes the impeller rotate.

Description

technical field [0001] The invention relates to an internal combustion engine. Background technique [0002] Various internal combustion engine arrangements are known, the most common of which include automatic cycle or four-stroke engines, two-stroke engines and Wankel rotary engines. Other engine types are also known, including those employing five or six engine cycles and gas turbines. Two- and four-stroke internal combustion engines employ pistons that reciprocate within cylinders. The combustion action in the cylinder drives the piston to reciprocate back and forth in the cylinder, and through the connecting rod connected to the piston, the power generated by the reciprocating movement of the piston drives the crankshaft to generate rotational power output. The Wankel engine did not use reciprocating pistons. Instead, it uses an eccentric shaft that rotates in an oval cavity for intake, compression, ignition and exhaust. A gas turbine is also a rotating machine that...
