In an opposed-piston mechanism, an intake compression cylinder (1) and an expansion exhaust cylinder (2) are individually provided, and a rotating perforated columnar valve (3) and an ignition combustion chamber (4) are formed therebetween. A valve mechanism is arranged on a cylinder side surface side, and a disk cam (7) that moves in conjunction with crank rotation operates an intake valve (33) and an exhaust valve (34) on a cylinder side surface via a movable fulcrum type rocker arm (8). A movable structure of the rocker arm also realizes opening / closing amounts of the intake valve (33) and the exhaust valve (34) according to an operating situation of an engine. Since a piston pin (18) and a piston pin (30) can absorb variations of an engine that occur when two connecting rods are connected to one piston, the two connecting rods can be easily connected to the one piston.

Cylinder arrangement for an internal combustion engine with a cylinder housing (4) in which a working piston (8) is provided, wherein the cylinder housing (4) is closed at a first end by a cylinder cover (6) movable by means of a first drive device (20), the cylinder cover having a cover circumferential surface (16), such that a combustion chamber (10) is formed between the working piston (8) and the cylinder cover (6), wherein a slide arrangement (18), which can be actuated by a second drive device (44), is provided for opening and closing combustion air inlet openings (32) and exhaust gas outlet openings (34) arranged in the cylinder housing (4), wherein the cylinder cover (6) is movably arranged such that an overlap in the radial direction of the cover circumferential surface (16) with the combustion air inlet openings (32) and exhaust gas outlet openings (34) is possible, characterized in thatthat a circumferential edge of the cover circumferential surface (16) directed towards the combustion chamber (10) has a number of angled sections (72) corresponding to the combustion air inlet openings (32) and exhaust gas outlet openings (34).

A simple positive displacement turbine engine has been discovered in which all reciprocating, oscillating and / or elliptical mass is eliminated. This special dual axis turbine engine masters near ideal & complete base four (4) Internal Combustion Engine (ICE) cycles namely; Intake, Compression, Expansion & Exhaust and further perfects them with a single draft cycle between the Intake & Compression cycles and another single draft cycle between the Expansion & Exhaust cycles for a total of six (6) cycles all completed within one (1) 360 degree rotor revolution. The combination of the intrinsic low friction & highly efficient conversion of chemical & thermal reaction into mechanical work and significantly improved cycling results in extremely high specific power and significantly improved Brake Thermal Efficiency (BTE) such that complicated, costly & problematic Variable Valve Timing (VVT) & Direct Fuel Injection (DI) systems can add no additional benefit. And yet the core moving parts (not counting roller bearings) can be reduced to as little as two (2) Intersecting rotors on dual axis and no more than four (4) where timing gears are necessary. Despite its unmatched simplicity the here disclosed special dual axis turbine engine is capable of efficiently generating high compression ratios in excess of 35: 1 @ low speeds and 40: 1 @ higher speeds without aid of external boost. Combined with the ability to initiate ignition of a vast array of combustible fuels, including Hydrogen, by multiple optimally optional means (ie Spark, Glow, Auto, Etc.) in advance of minimum combustion chamber volume without any negative work produced. Industrially significant improvements in power density, BTE AND harmful emission mitigation and even elimination are mathematically and dependably obtainable.

The present application relates to the technical field of motorcycle engine manufacturing, in particular to an engine starting decompression mechanism and a motorcycle, comprising an engine body, further comprising a valve top cup, the valve top cup is composed of a valve cover and a valve rod, a rotary pressure valve for conducting and discharging compressed air is installed inside the valve cover, an exhaust mesh cover for exhaust is installed on the valve cover, an exhaust hole for discharging compressed air is formed at the lower end of the rotary pressure valve; a valve core lifting rod for opening and locking the rotary pressure valve is slidably installed in the valve rod; the cam block drives the valve core lifting rod to slide up and down, through the cooperation of the rotary pressure valve and the valve core lifting rod, the problem that the starting mechanism needs to be triggered every time the engine starts is solved, thereby improving the use efficiency of the starting decompression mechanism, reducing the invalid use frequency of the decompression mechanism, and prolonging the service life of the mechanism.

An engine rotating valve type rotary servo valve mechanism, including valve core (1), valve seat (2), inlet and outlet manifold (3), one-way diaphragm (18), one-way diaphragm (19), engine cylinder and servo rotary motor; The servo valve method of the engine rotating valve type servo valve mechanism is to use the servo rotary motor as the power to drive the valve core (1) to rotate inside the valve seat (3), and to use the rotary transformer to monitor and accurately control the rotary position of the inlet valve core (1) relative to the valve seat (3), to realize the opening and closing between the inlet and outlet grooves and the corresponding inlet and outlet ports, so as to realize the stop of the valve. The device has the advantages of compact structure, stable gas supply, convenient use and adjustment, etc., can effectively reduce the vibration of the engine due to the valve, improve the engine efficiency, and has good market prospect.
