Patent ID: 8322320

Claim:
In a four-stroke combustion engine, powered by ethyl alcohol, methyl alcohol and petrol, kerosene, benzol or benzene, that includes a cylinder having a combustion chamber and an axis, a cylinder head, a fuel injector and a suction valve, a laser ignition device that comprises: a pulse laser built-in on the cylinder head that emits a pulsed laser beam in the cylinder axis, close to the cylinder axis, or at an angle to the cylinder axis, the pulse laser comprising: a housing including an outer sleeve and a slidable sleeve having an outlet; a window of transparent material seated at the outlet of the slidable sleeve, wherein the material is resistant to temperature and pressure changes within the combustion chamber of the cylinder of the engine; two arms of steel material connected to the outer sleeve of the housing; and a junction between the two arms; a dumper fixed in the junction of the two arms and having a flat matted operation surface, wherein the flat matted operation surface comprises a diameter that is perpendicular to an axis of the pulsed laser beam, wherein the diameter of the flat matted operation surface is not less than double a diameter of the pulsed laser beam, wherein the dumper is made of tungsten, tantalum or platinum; and wherein in a front view, the two arms have an outline of slightly curved bows with a pass at the base for accommodating the dumper or an outline of an even-armed trapezoid; and a control-operation system comprising: a computing module that is operative based on received data concerning the combustion process, an ignition setup process, and a process of thermodynamic engine circulation; and a control module that controls emission of the pulsed laser beam, the fuel injector and the suction valve.
