A method for introducing combustion air into a cylinder (25) of an internal combustion engine, a high-pressure inlet valve (1) provided therefor and an internal combustion engine that operates using the method and the high-pressure inlet valve are described. All the combustion air for the respective cylinders (25) is introduced into the cylinder (25) of the internal combustion engine, by means of a high-pressure inlet valve (1) arranged in the relevant cylinder head (26) and on the basis of a controlled mass flow, such that mixture formation and charge exchange are intensified. In addition, the temperature and/or pressure of the combustion air is measured and the quantity of combustion air is introduced into the cylinder (25), in a controlled manner and on the basis of the measurement results, by means of the high-pressure inlet valve (1) by opening or closing a sliding piston (3) of the high-pressure inlet valve (1) by displacement. As a result of an axial displacement of the sliding piston (3) between guide sections (5) in the housing (2) of the high-pressure inlet valve (1), passage areas (6) for combustion air are blocked in a closed position (7) and opened in an open position (8). In the passage area (6), the sliding piston (3) has two pressurization areas (10, 11) facing each other, the surfaces of which are of equal size or differ from each other when projected in one plane. The first pressurization area (10) can be designed as a poppet valve (12) and the second pressurization area (11) can be designed as an annular surface (13). The internal combustion engine has a high-pressure line (27) for the combustion air, which line is connected to the high-pressure inlet valve (1). With respect to the longitudinal axis of the cylinder (25), the high-pressure inlet valve (1) is arranged in the cylinder head (26) in an upright or horizontal position.

A sequencing manifold for the purpose of supplying control and supply services of pre-determined temporal sequences to fluid processing assemblies is provided. The functioning of this sequencing manifold requires that translation be applied to the sequencing ports. Actuator mechanisms may supply such translation as either continuous motion or as a series of stepwise motions. Actuator mechanism can be obtained that rely on only mechanical means without the need for a source of electricity. With such actuators, it becomes feasible to conduct the operations of fluid processing assemblies in remote and primitive locations that lack a source of electricity. One skilled in the mechanical arts can provide various actuator mechanisms to meet these requirements.

The present disclosure relates to a valve, preferably an exhaust gas or gas exchange valve, having a valve head which has a front face and a rear face, the front face of the valve head including an edge region and a bulge towards the outside which has a crest region. The valve, in order to reduce the mass of the bulge of the valve head, including a laterally outer part section of the edge region that is of flatter configuration in comparison with a laterally inner part section of the edge region, or the edge region includes at least one discontinuity in cross section.

Apparatus for controlling valve timing in an internal combustion engine locates a first valve port in a first side of the engine cylinder and a second valve port in a second side of the engine cylinder. A first rotating valve disc and a second rotating valve disc are respectively disposed next to the first and second valve port. Each rotating valve disc includes a valve port. Each disc rotates in synchronism with the crankshaft to align its' port with the respective first and second valve ports. A variety of intake devices coupled to the first rotating valve disc control intake air flow into the engine cylinder, and a variety of exhaust devices coupled to the second rotating valve disc control exhaust gas flow from the engine cylinder.

Engine for producing mechanical energy by internal combustion of a fuel includes a shaft and a crank arm attached to the shaft. The engine further includes a casing, where the interior of the casing forms a hollow cavity dimensioned to allow the crank arm to rotate within the hollow cavity and the crank arm is capable of making a seal with the interior surface of the casing to block fluid passage. The interior of the casing also includes a bypass area that allows fluid passage around the crank arm. A first valve is positioned adjacent to the bypass area and a second valve is positioned adjacent to the bypass area opposite from the first valve. The first valve and the second valve are configured to block fluid passage when closed.

The figures included below with the description of attributes are intended to convey an understanding of the mechanical principles underpinning the operation of the sequencing manifold. For reasons of clarity, the figures depict configurations involving apparently geometrically flat plates rather than more complex configurations involving cylinders or circular discs. The omission of configurations involving cylinder or discs from the figures included with this application is not meant to be limiting in any manner.

Self-cooled engine including a cylinder, a cylinder head and a turbo-piston which freely reciprocates inside the cylinder. The cylinder head has a valve that achieves circumferential suction of air-fuel mixture into the cylinder. The valve mechanism is closed and opened by cylindrical cam by means of cam shaft. Circumferential suction of air-fuel mixture enables the cylinder to cool itself and to burn the fuel at the energy center effectively. The force of incoming stream of air-fuel mixture rotates the impeller on the piston which acts as a fan to cool the cylinder walls. The impeller blades deflect the flame from reaching the cylinder walls and acts as a thermal barrier between the energy center and cylinder walls. The high intensity compression swirl (HICS) created at the end of the compression stroke to ensure that the fuel combustion is efficient and instantaneous release of maximum energy.

An exhaust valve includes a toroidal surface about an axis of rotation of the valve. The toroidal surface is positionable over a central exhaust port of an engine when lowered. The valve is raised by an actuator in response to increasing rotational speed of the crankshaft of the engine, thereby enlarging and raising the effective opening of the exhaust port. Lateral valve surfaces on either side of the toroidal surface close lateral exhaust ports when the valve is lowered. The lateral valve surfaces may be cylindrical and formed on fins.
