A rotary internal combustion engine is disclosed and generally comprises a rotor means which is rotatably mounted on a stationary core mounted in an engine frame. The rotor means has a plurality of cylinders spaced radially thereon. A free floating piston is slidably mounted in each of the cylinders with the heads of the pistons being positioned towards the center of the rotor. A roller is mounted in the skirt end of the piston which rides against a circular cam. The centrifugal force created by the rotation of the rotor causes the pistons to follow the internal cam surface of the cam during rotation. The inner end of the core is provided with fuel and air ports adapted to communicate with the cylinders as the rotor rotates with respect to the core. An air passageway is formed in the core and is in communication with the air port and an air pump to provide a supply of air for purging, cooling and charging the cylinders. A fuel passageway is provided in the core and is in communication with the fuel ports and a supply of fuel to supply fuel under pressure to the fuel ports. An adjustable needle valve is provided in the fuel passageway to permit the precise adjustment or metering the fuel being supplied to the fuel ports. Ignition is accomplished through compression with the cam being shaped so that the compression is increased as the piston approaches its position of maximum compression. The cam is shaped to provide a dwell adjacent the area of maximum compression to permit the piston to be maintained at the position of partial expansion to permit complete combustion of the fuel-air mixture to increase combustion efficiency. The cylinders are exhausted by means of openings extending around the cylinder. The exhaust from each cylinder is exhausted through its individual exhaust openings with the exhaust in the cylinder being purged by the air being supplied thereto from the air pump. The air also permits the cylinders to be recharged and forces the pistons radially outwardly into engagement with the cam. The air also cools the inside surface of the cylinder. The preferred embodiment includes an even number of cylinders, ordinarily two or four with a cam plate having a pair of oppositely disposed lobes. The preferred cam plate is designed to condense the compression stroke and the expansion stroke into a shorter period of time so that less heat is lost to the walls of the cylinder therefore requiring less cooling. The shortened compression and expansion time also permits additional time for the cooling cycle.

An internal combustion engine including internal cavities slidingly receiving a respective piston to define a respective combustion chamber, at least one inlet port for each internal cavity in fluid communication with the combustion chamber at least during the intake phase and a beginning of the compression phase, at least one exhaust port for each of the internal cavities and in fluid communication with the combustion chamber during the exhaust phase, a plenum for receiving pressurized air, and conduits in fluid communication with the plenum. Each conduit defines a fluid communication between a first respective internal cavity and a second respective internal cavity through the inlet ports. The combustion chamber of the first respective internal cavity undergoes the beginning of the compression phase simultaneously with the combustion chamber of the second respective internal cavity undergoing the beginning of the intake phase.

A method for controlling the compression ratio null in a supercharged combustion engine. The latter is provided with a control device in which a maximum final compression temperature T2,max is ascertained, and, within the framework of a precontrol, an optimum efficiency compression ratio nullopt is ascertained. The knock limit is determined from the compression ratio null, to which it corresponds, and which is ascertained from the precontrol. As a function of the efficiency curve in the characteristics map nullnullf, a further change occurs in compression ratio null or a setting back of the change in compression ratio null. The values learned for null and the ignition angle as a function of the operating point are permanently stored in a characteristics map to which the engine control has access.
摘要:
A rotary internal combustion engine is described and shown having two piston and cylinder assemblies rotating about a single axis. The pistons reciprocate in rotating cylinders having a four cycle internal combustion engine process to receive air and fuel, to compress the air and fuel, to combust the mixture and to exhaust the gases therefrom. The pistons move in a set relation to each other, being connected by a common rod. The center of rotation of the pistons is dynamic relative to the center of rotation of the cylinders and cylinder blocks. Intake and exhaust valves are positioned about the periphery of the rotor assembly, and have staggered opening and closing schedules in order that air and fuel may be admitted and gases scavenged in accordance with the four cycle internal combustion engine principle. Rotating valve members having diametrical passages are rotated by a common drive, but positioned relative to each other so that their openings sequentially open and close to coordinate with the rotating rotor assembly. Alternative embodiments for use as a compressor are described.

A method for controlling the compression ratio ε in a supercharged combustion engine. The latter is provided with a control device in which a maximum final compression temperature T2,max is ascertained, and, within the framework of a precontrol, an optimum efficiency compression ratio εopt is ascertained. The knock limit is determined from the compression ratio ε, to which it corresponds, and which is ascertained from the precontrol. As a function of the efficiency curve in the characteristics map η=f, a further change occurs in compression ratio γ or a setting back of the change in compression ratio ε. The values learned for ε and the ignition angle as a function of the operating point are permanently stored in a characteristics map to which the engine control has access.
摘要:
An engine including a piston yoke assembly reciprocating within a rotor assembly disposed for rotation within a fixed casing. The rotor assembly is of elliptical configuration to form a pair of exhaust chambers located between the assembly and the casing interior. The rotor assembly defines closed end combustion chambers and fuel-air chamber within which the yoke portion of the piston yoke assembly reciprocates to pressurize fuel-air charges for transfer to the combustion chambers. The piston yoke assembly comprises a part of the rotor assembly but moves about a fixed component carried by the engine casing resulting in reciprocal movement of the piston yoke assembly within the rotor assembly. Power is delivered to the rotor assembly by ignition of a fuel-air charge acting on a piston and yoke assembly off center from the fixed casing component. Exhaust ports within the rotor assembly provide for the ejection of exhaust gases asymmetrical to the rotor axis to impart torque to the rotor. Engine cooling is accomplished by the admission of ambient air to the pair of exhaust chambers and by heat transfer from engine pistons to a fuel-air mixture. In a second described form of the engine the rotor assembly is provided with blades which move a cooling air flow axially through the fixed casing. The second engine form further includes ignition components located on the forward side of the rotor assembly. Combustion gases are exhausted from the casing interior by a barrier riding on the rotor periphery.
摘要:
An invention is provided for a new and novel intake/exhaust device for an internal combustion engine. A rotating cylinder having an intake/exhaust port penetrating the outer surface of the rotating cylinder and meet at an axis of rotation and have a connective relationship which allows fluid to flow easily. The rotating cylinder when used in a 4-stroke engine aligns the intake port with the combustion chamber, and when rotated will align the exhaust port with the combustion chamber each at the correct time. This novel invention overcomes the limitations of current valve trains by only using rotation, and not by using rotation and linear motion to activate valves thereby allowing the engine to attain much greater RPMs.
