Abstract:
An internal combustion engine comprising: a cylinder; a piston located in the cylinder and connected to a crankshaft for reciprocal motion with respect to the cylinder, and defining a combustion chamber with the cylinder; a fuel injector to selectively inject fuel into the combustion chamber; an oxidising agent injector to selectively inject oxidising agent, into the combustion chamber; a water injector to selectively inject water into the combustion chamber; an exhaust valve to selectively open and allow exhaust gases to be expelled from the combustion chamber; wherein the engine is configured such that water is injected by the injector after combustion of the fuel has commenced.
Abstract:
The invention relates to an arrangement (1) for a compression ignition engine (11) comprising one or more combustion spaces (12) defined by a piston (3) and the inner walls of a cylinder (4), the combustion space (12) being supplied with fuel when the piston is close to its upper dead-centre position and the volume of the combustion space (12) is at minimum or close to its minimum. In the invention, gas in the combustion space (12) is compressed by means of a piston (3) before fuel and/or oxygen necessary for combustion is introduced into the combustion space, so that the gas pressure generated in the combustion space (12) generates an adequate compression pressure for the fuel supplied into the combustion space under adequate pressure and/or for the oxygen necessary for combustion, while said compression pressure is such that the fuel introduced into the combustion space (12) has auto ignition. The oxygen introduced into the combustion space (12) and necessary for fuel combustion is derived from a tank (6; 6a), where it is maintained in a liquid state, and said gas is introduced into the combustion space under adequate pressure exceeding sufficiently the highest working pressure.
Abstract:
Air is cooled to conditions where the oxygen component of the air is liquid and the nitrogen component of the air is gaseous using fuel for an engine as a heat sink. The oxygen is separated from the nitrogen and the oxygen supplied to the engine for combustion.
Abstract:
A system for controlling combustion in a diesel engine having one or more combustion chambers in which fuel is injected and air is compressed for combustion of the fuel. The system includes a hydrogen injector for injecting a first predetermined volume of hydrogen into the combustion chamber prior to combustion of the fuel, and an oxygen injector for injecting a second predetermined volume of oxygen into the combustion chamber prior to combustion of the fuel.
Abstract:
A 2-stroke internal combustion engine comprising: a cylinder; a piston located in the cylinder and connected to a crankshaft for reciprocal motion with respect to the cylinder, and defining a combustion chamber with the cylinder; a fuel injector to selectively inject fuel into the combustion chamber; at least one inlet valve to selectively deliver pressurised oxidising agent into the combustion chamber; at least one exhaust valve to selectively open and allow exhaust gases to be expelled from the combustion chamber and means for varying the exhaust valve operating characteristic.
Abstract:
Sistema que mejora la combustión y por ende la eficiencia, aprovechando la potencia energética del diesel, gasolina, gas licuado, gas natural, logrando producir una combustión eficiente, aumentando la potencia y fuerza del motor, que genera e incorpora pequeñas cantidades de hidrógeno (66%) y oxígeno (33%) como gas, como cada molécula de hidrocarburo (diesel) necesita una molécula de oxígeno para la reacción, la incorporación de oxigeno puro enriquece el amiente de combustión, el hidrógeno en gas ayuda a quemar todo el diesel de la cámara de combustión, entonces, ya no tenemos carboncillo en las paredes de la cámara, aceite sucio, ni humos en el escape, siendo la reacción química de la combustión resultante, ahora tiene vapor de agua como emisión y mucho menos contaminantes reactivos, además, como la eficiencia de combustión aumenta la potencia, entonces el sistema reduce el flujo de combustible de manera tal, que la potencia vuelva a los rangos iniciales, economizando combustible, siendo en el caso de motores que trabajan en alturas o faenas mineras donde la densidad del oxígeno es mínima, el sistema incorpora el oxígeno puro que falta de manera tal, que el motor no pierda potencia pues su rango de trabajo es similar al que tendría a nivel de mar.
