摘要： PURPOSE:To surely improve air exchange efficiency by providing a movable shaft of another valve in a hollow movable shaft of a valve, and independently operating the outside valve and the inside valve respectively. CONSTITUTION:A combustion chamber is opened/closed with a duplex valve 1, 2 in which a movable shaft of another valve is provided in a hollow movable shaft of a valve. When the valve 2 is opened, at first the outside valve D is opened to generate a same flow A as a customary flow, hereafter the inside valve E is opened to generate a new flow B through holes C opened in the outside valve D. Hereby, air exchange efficiency can be surely improved.

摘要： PURPOSE:To fill gas in cylinder uniformly while to increase the exhausting speed by arranging intake and exhaust valves coaxially with the cylinder thereby increasing the valve area. CONSTITUTION:An intake or exhaust valve 2 is arranged in the center of the cylinder head 3 coaxially with the cylinder 4 while an exhaust or intake valve 1 is arranged coaxially. Consequently, the valve area can be increased to improve the intake/exhaust efficiency. Since gas is filled through an intake port coaxial with the cylinder 4, it is filled uniformly. Furthermore, the combustion chamber can be made flat and the compression ratio can be increased.

摘要： PURPOSE:To thermally deform a valve seat part in an axis of symmetry and prevent a blow-by in the seat part, by providing a unified valve used in common for intake and exhaust in the center of a cylinder cover while a control valve respectively in intake and exhaust passages communicating with the unified valve. CONSTITUTION:A port used in common for intake and exhaust is formed in the center of a cylinder cover, being opened and closed by a unified valve 2. This port communicates with an exhaust passage 8, exhaust pipe 6, intake passage 9 and an intake pipe 7. The exhaust passage 8 and the intake passage 9 respectively provide an exhaust control valve 4 and an intake control valve 5. The intake control valve 5 and the unified valve 2 are opened by closing the exhaust control valve 4 in an intake stroke, while the exhaust control valve 4 and the unified valve 2 are opened by closing the intake control valve 5 in an exhaust stroke. The unified valve 2, thermally deforming its seat part in an axis of symmetry, prevents a blow-by in the seat part.

摘要： PURPOSE:To obtain valve timing of an engine smoothing the action of its valve and enabling its high speed running, by utilizing a cavity in a piston so as to increase a lift of the valve when the piston is positioned in its top dead center. CONSTITUTION:An engine, not having a throttle valve, performs intake and exhaust operation by a single valve 1. In an exhaust stroke, exhaust gas is allowed to flow out from a reed valve 4 via a guide plate. An intake port 2, branching and providing a reed valve 4', never causes an inflow of the exhaust gas. A piston 7 never collides against the valve 1 by providing a cavity 8 in the piston 7 even if a valve lift (h) is in its maximum when the piston is placed in its top dead center at the intake and exhaust operation of the engine. Accordingly, the valve never generates its dancing action at high speed running by forming a cam in a smooth shape.

摘要： PURPOSE:To form an engine in light weight and promote its cost down, by controlling intake air and exhaust gas through a valve for combined use of the intake air and the exhaust gas, in the case of the cylinder injection four-cycle engine without having a throttle valve. CONSTITUTION:A cavity 2a in the upper part of a piston 2 forms in a cylinder 1 a combustion chamber into which fuel is injected through a unit injector 4. A combined intake and exhaust port is provided and controlled to be opened and closed by a combined intake and exhaust valve 6. While two passages are connected to the port, and an intake passage 15 branches from an exhaust passage 14. Exhaust gas is prevented from mixing in intake air by providing a guide plate 18 to be formed in the vicinity of a branch part.
