INTERNAL COMBUSTION ENGINE Russian patent published in 2005 - IPC

FIELD: mechanical engineering.

SUBSTANCE: invention relates to engines using water in working cycle. Proposed four-stroke internal combustion engine contains at least one cylinder, cooling system, piston and cylinder head forming combustion chamber, outlet valve, pump and nozzle to deliver liquid into cylinder and working mixture igniter. Nozzle is provided with cavitator. Igniter is made in form of electrodes with adjustable gas in between to which direct current is supplied for striking and extinguishing the arc. Electrodes are installed in combustion chamber. Electrolyte is used as liquid, for instance, water solution of potassium hydroxide. Water in combustion chamber dissociates into hydrogen and oxygen under the action of electric arc. Cavitator of nozzle is made in form of local narrowing of its channel. Active insert of electrode is made of solid refractory material, and its holder is made cooled. Active insert of electrode is made hollow, of refractory material, and is cooled by liquid from inside. Holder of active insert of electrode adjusting the gap is installed on thread in electrode housing with possibility of adjusting the gap between electrodes and fixing of holder of active insert by locknut, holder of active insert of arc striking electrode is installed in housing of electrode with possibility of reciprocation at moment of striking of electric arc owing to spring and distributing camshaft set into rotation from engine camshaft. Delivery of current to electric arc electrodes and short-time interruption of delivery of current at extinguishing of electric arc is provided by closing and opening of contacts of distributor breaker.

EFFECT: provision of fuel-saving ecologically clean internal combustion engine.
