Abstract: Internal combustion engine comprising a cylindrical work chamber (1) with a piston (3) sliding therein, said work chamber being closed by a cylinder head (4), a device (5) operating in two stroke mode, for injecting liquid fuel atomized under high pressure, a system for loop scavenging through the cylinder head and two valves having the same cylindrical form and axes. The outer inlet valve (7) cooperates with a cylinder head seat (15), the other valvebeing an exhaust valve (6) of tubular shape which has a surface bearing against a seat (16) formed in the lower portion of the inlet valve (7). The inle valve opens into the work chamber and the exhaust valve opens in the opposite direction, thereby delimiting, between them, an exhaust passage (8). The injection device (5) opens into the work chamber substantially at the centre of a central hub (21) on the cylinder head, the exhaust valve (6) sliding along said hub.

Abstract: An inlet and exhaust valve in internal combustion engines is described in the form of a vessel, designed with a large through cavity in its interior. The valve has two guide-­rods (8, 9) and two seating zones (1, 2), one on its internal side in which a conventional valve is fitted, and the other (1) on its external side where it itself fits onto the cylinder head.
The design of this valve allows it to have a large dimension and from which it adjusts on its inside, factors which result in an increase in the combustibility of the gases, improving the efficiency of the engine. This improvement brings with it in addition a reduction in the emission of pollutant gases.

Abstract: This invention presents a method to improve the volumetric efficiency of a reciprocating internal combustion engine using a common transfer port between the exhaust and intake port. The engine employs a poppet valve as part of the intake and exhaust valve to control the flow from the transfer port into the combustion chamber. Two plate type valves outside of the combustion chamber are located at both ends of the transfer port to control the flow coming from the intake and out the exhaust. The timing for opening and closing of the poppet type valve is regulated to remain open for a longer duration which provides complete evacuation of air in the exhaust stroke. The ejector effect from the exhaust flow through the transfer port draws a vacuum into the cylinder. When the exhaust plate closes, the vacuum diverts the intake into the cylinder.

Abstract: An internal combustion engine is provided in which an intake valve, which opens and closes an intake valve hole formed in a cylinder head facing a combustion chamber has a hollow structure. An exhaust valve hole formed in the intake valve is made to open and close by an exhaust valve coaxially housed within the intake valve. The intake valve hole communicates directly with an intake port, and the exhaust valve hole coniniunicates with an exhaust port via an exhaust passage formed within the hollow intake valve. This ensures that the intake valve has a large opening area, thus increasing the intake charging efficiency. Furthermore, since exhaust gas coming out of the combustion chamber does not make direct contact with the cylinder head, which has a large heat capacity, any decrease in temperature of the exhaust gas can be minimized, thereby utilizing waste heat effectively.

Abstract: A four-stroke piston engine in which air or a fuel-air mixture is drawn into a cylinder. Fuel may be injected into the air flowing into or already present in the cylinder while a further fuel supply is located on the axis of the cylinder and supplies at least one jet of fuel during the compression stroke, which jet of fuel in cooperation with the fuel-air mixture forms at least one zone of enriched mixture within the cylinder. The piston may have a recess in the upper end into which the fuel nozzle is received when the piston approaches top dead center so that an enriched zone is formed in the recess or in the region of said recess which can be ignited by electrodes disposed adjacent the further fuel supply.
