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: Dual fuel compression ignition engines and methods that allow compression ignition on gaseous fuels like compressed natural gas, hydrogen and ammonia, yet will run on liquid fuels, including diesel fuels for such purposes as starting or when the gaseous fuel is not available or has been consumed and greater range or operating time is needed. Ignition of fuels having a high self ignition temperature is assured by recirculating high temperature exhaust gas back into the intake charge before compression. Existing engines may be converted to run as a dual fuel engine by replacement of the engine head or heads. Various embodiments are disclosed.

Abstract: An intake and exhaust device for an internal combustion engine with direct injection comprises an intake and exhaust valve (11) with a stem (13), a head (12), and a seat (24) facing a combustion chamber (CC) of the engine (M), and intake duct (42) for the intake of air into the combustion chamber (CC), and an exhaust duct (38, 57) for the discharge of the exhaust gases, the exhaust duct (38, 57) being connected to the intake duct (42) upstream of the valve seat (24). The exhaust duct (38, 57) is arranged so as to be coaxial with the valve (11) and the intake duct (42) extends radially. The connection between the intake duct and the exhaust duct (38, 57) is in the vicinity of the seat (24) of the valve (11) so that the exhaust gas-flow conveyed through the connection has a radial velocity component directed towards the valve stem (13). The air is drawn in from the intake duct (42) as a result of the gas-flow passing through the exhaust duct (38, 57) during the exhaust phase and as a result of the movement of a piston (P) in the cylinder during the intake phase.
