Piston-type four-stroke cylinder-changing gas distribution engine

Abstract

The invention discloses a piston-type four-stroke cylinder-changing gas distribution engine which mainly consists of a crank shaft, a double-piston double-rod connecting rod, a double-cylinder body with a rotor shaft and an cylinder cap assembly, wherein the rotor shaft is positioned at the middle of a left cylinder body and a right cylinder body in the double-cylinder body, the top of the double-cylinder body is semicircular or hemispherical, and the top of the double-cylinder body is in sliding fit with the cylinder cap; and the double-piston double-rod connecting rod moves in the double-cylinder body, the double-cylinder body reflects around the rotating shaft of a cylinder in a reciprocation manner, the double-cylinder body, the air inlet and exhaust port of the cylinder cap and a middle public gasbag chamber air port naturally form a scavenging valve in an inswept manner, and the gas distribution of the piston-type engine is finished in a cylinder-changing manner. Compared with the prior art, the engine provided by the invention has the advantages of greatly improving the real output power of the engine, greatly reducing the manufacturing cost of the engine, reducing the barycenter of the engine and achieving the effects of synergism, energy conservation and emission reduction.

Description

technical field [0001] The invention belongs to an internal combustion piston engine, in particular to an internal combustion piston engine in which a rotatable cylinder and a connecting rod move synchronously to naturally form a cylinder-changing gas distribution mode. Background technique [0002] Existing piston four-stroke engines must have camshafts, valves (valve), valve springs, rocker arms, tappets, timing sprockets and chains or timing pulleys and belts, etc. Gas system, which accounts for a large proportion of the engine manufacturing cost; this kind of gas distribution system will consume a lot of useful work to keep the engine running again; mainly manifested in: when the power stroke will end and the exhaust will start, the gas in the cylinder will expand To the maximum, the pressure in the cylinder reaches the maximum, and the pressure per unit area in all directions in the cylinder is equal. At this time, the cam moves the valve from the outside of the cylinde...

Problems solved by technology

[0002] Existing piston four-stroke engines must have camshafts, valves (valve), valve springs, rocker arms, tappets, timing sprockets and chains or timing pulleys and belts, etc. Gas system, which accounts for a large proportion of the engine manufacturing cost; this kind of gas distribution system will consume a lot of useful work to keep the engine running again; mainly manifested in: when the power stroke will end and the exhaust will start, the gas in the cylinder will expand To the maximum, the pressure in the cylinder reaches the maximum, and the pressure per unit area in all directions in the cylinder is equal. At this time, the cam moves the valve from the outside of the cylinder to the inside of the cylinder to overcome the pressure in the cylinder and forcefully push the exhaust valve open, which consumes energy; the exhaust valve is in the cylinder. The larger the unit area, the greater the power consumption; but in order to breathe more fully, the valve is often made larger. It is conceivable that in order to keep the engine running again, a lot of useful work is consumed to drive the entire valve train to work. Complete the gas distribution process, which is an insurmountable shortcoming of all cam type gas distribution four-stroke engines

[0003] In addition, the special air distribution system of the existing piston engine occupies a large proportion in the manufacturing cost and the evaluation of the advanced nature of the engine. In fact, the advanced nature of an engine refers to the advanced nature of the air distribution system. Excellent air distribution ability There is excellent performance, however, this excellent performance must be a heavy burden of higher cost and power consumption

In a word: the existing piston engine has the disadvantages of high manufacturing cost and high power consumption, as well as high center of gravity and large volume
