    Abstract: A four-stroke piston engine in which air is drawn into a cylinder while rotary motion about the cylinder axis is imparted to the air. Fuel may be blown/injected into the air during its rotation in the cylinder while the fuel supply is located on the axis of the cylinder and supplies at least one jet of fuel directed radially outwardly and which jet of fuel in cooperation with the rotating air forms at least one helical stream of mixture within the cylinder, preferably during the compression stroke, which is transformed into a coherent mixture zone enclosed by a ring of air upon completion of compression. The piston may have a recess when the piston approaches top dead center so that an enriched zone is formed in the lower region of the compression space which can be ignited by electrodes disposed in said lower region of the compression space.

    Abstract: A poppet valve (13) has a valve body (14) and a closure member or valve stem (17) disposed in a bore (23) in the valve body. The interior of the valve body is hollow, and is closed at one end. When the valve is open, fluid passes into the interior of the closure member (17) through apertures (22) and passes along the interior of the closure member. The valve (13) can be located in the cylinder head of a marine propulsion unit to act as a purge port (9) of a post-immersion restart system.

    Abstract: An improvement to loop-scavenged two-stroke internal combustion engines with an intake valve (7) engaging a seat (10) for fresh air intake, and an exhaust valve (8) engaging a seat (13) for combustion gas exhaust, is disclosed. The valves are arranged in such a way that the fresh air intake scavenges a susbtantial part of the burnt gases. In at least one of said valves, the valve surface (21) located downstream from the valve face (9) and the surface (23) of the downstream extension of said seat (10) are configured in such a way that they form a substantially isentropic diffuser.

    Abstract: An internal combustion engine, wherein an intake valve (9) for opening and closing an intake valve hole (7) formed in a cylinder head so as to face a combustion chamber (5) is formed hollow, an exhaust valve hole (22) formed in the intake valve (9) is opened and closed by an exhaust valve (18) stored coaxially inside the intake valve (9), the intake valve hole (7) facing the combustion chamber (5) communicates directly with an intake port (8) and the exhaust valve hole (22) facing the combustion chamber (5) communicates with an exhaust port (14) through an exhaust gas passage (21) formed inside the hollow intake valve (9), whereby the intake air charging efficiency can be increased by largely assuring the opening area of the intake valve (9), and the lowering of temperature of the exhaust gas can be minimized to effectively use waste heat since the exhaust gas just after leaving the combustion chamber (5) is not brought into direct contact with the cylinder head (3) having a large heat capacity.
