Abstract: A system for an internal combustion engine can include a separation device and an engine component including first and second valves. The separation device can separate intake air into a volume of nitrogen-rich air and a volume of oxygen-rich air. A first valve element can be movable relative to a first valve body and can have an annular shape disposed about a central axis of the combustion chamber. The first valve body can be fluidly coupled to the separation device and direct the oxygen-rich air into a central area of the combustion chamber. A second valve element can be movable relative to a second valve body and can have an annular shape disposed about the central axis, radially outward of the first valve. The second valve body can be fluidly coupled to the separation device and can direct the nitrogen-rich air to a peripheral area of the combustion chamber.

Abstract: A second exhaust poppet valve 9 is provided in a portion of a combustion chamber expanded out of a main cylinder 1. A valve cover 7 reciprocates within a sub-cylinder 4 and covers a bottom surface of the second exhaust poppet valve 9. A first exhaust valve 10 and an intake poppet valve 11 are provided so as to face an upper surface of a piston 2. After the second exhaust poppet valve 9 is opened and hot high-pressure burned gas starts to flow away, the first exhaust poppet valve 10 is opened. As a result, the temperature of the first exhaust poppet valve 10 is reduced and the compression ratio can be increased. Then, a work amount of the piston is increased. The increased work amount compensates an amount of cooling loss due to increasing a surface area of the combustion chamber.

Abstract: A five-valve per cylinder internal combustion engine having a lens shaped combustion chamber that promotes a high compression ratio and which also reduces the likelihood of knocking. The engine includes a cylinder head having three intake valves disposed substantially on one side of a plane containing the cylinder bore axis and a pair of exhaust valves supported for reciprocation on the other side of the plane. The intake valves are disposed at acute angles to a plane containing the cylinder bore axis and containing the axis of rotation of the camshaft. The center of these poppet valves is disposed of on a plane also containing the cylinder bore axis and perpendicular to the first plane, while the remaining intake valves are disposed at opposite acute angles to this plane. The poppet valves are actuated by a camshaft journaled in bearing surfaces formed directly in the cylinder head and through tappets that are supported in bores formed integrally in the cylinder head. The bolting arrangement for the cylinder head and camshaft bearing caps facilitates machining and simplifies assembly. The timing of the drive of the camshaft for operating the intake valves can also be varied relative to the rotational position of the crankshaft so as to reduce or preclude knocking.

The engine provides a piston crown utilizing a connecting rod directly connected to the bottom surface of the piston crown. The piston crown is stabilized along the longitudinal cylinder axis by a rail guide. Connecting rods are provided which require less than one hundred eighty degrees (180.degree.) circumference of a crankshaft pin for support so that a plurality of connecting rods can be associated with a single crankshaft pin. A tabbed bearing fits under the plurality of connecting rods to provide lubrication between the connecting rods and the crankshaft pin. Connecting rods are held to the crankshaft pin by a circular retaining ring. The engine provides a separate cylinder head and cylinder which are attached via a circular deformable retaining band to form a metal to metal seal. The engine provides an independent lubrication system in each engine. Coolant or lubricant is provided to each engine in parallel so that the temperature of the coolant entering each engine is the same. A large diameter modular crankshaft is provided.
