| CLAIMS Classic two stroke valve-less petrol engine, which operates without added lubricating oil to the fuel-air mixture differing from the current two stroke engine, for the operation of which the addition of lubricating oil to the fuel is necessary for the lubrication of rolling bearings and friction surfaces of the cylinder(s) and piston(s). The invention is characterized with a combustion process that does not include burned lubrication oil in the exhaust gasses. In addition it is characterized with the fact that it operates with lubrication of the crank mechanism and the piston cylinder group, which is separated from the combustion process. It is characterized by special cylinder design in which the intake and exhaust ports are not connected to the crankcase, but directly supply the combustion chamber with compressed air via compressor. |
VALVE LESS TWO STROKE INTERNAL COMBUSTION ENGINE
OPERATING
Valve-less two-stroke internal combustion engine, operating without addition of lubricating oil to the air-fuel mixture.
It belongs to the category/class of internal combustion engines.
It can be used in motor vehicles, automobiles, motorcycles, boats and flotation vessels, all mechanical units and other facilities/equipment that require to be mechanically driven.
The current valve-less two-stroke engine operates with fuel mixture in which it is necessary to mix a certain amount of lubricating oil to the fuel, or
lubricating oil to be added in the fuel mixture through mechanical oil pump. In all such instances the oil added to lubricate the piston rod-crank mechanism and piston-cylinder group is a part of the air-fuel mixture and is burned, which results in high level of pollution of exhaust gases.
The engine presented here has separate lubrication, as the specific to the engine lubrication oil quantity is added to its crankcase, or if necessary an oil pump is added according to the needs of the engine's load.
The piston of the engine has a specific design, as it features both compression segments) and oil/lubrication segnlent(s), the later provide(s) the lubrication of the cylinder surface and prevents the oil from passing above the piston and entering the combustion chamber.
The clearing and the induction of the cylinder with fresh air (or fresh air- fuel mixture) is realised through a rotary vane compressor, and could be realized via other reciprocating, screw, centrifugal or other type of compressors necessary for the proper operation of the engine, which is calculated precisely depending on the displacement and design of the engine and directly driven by the crankshaft of the engine.
The supply of fuel to the cylinder is performed by fuel injection system. Carburetion supply of air-fuel mixture can also be utilized.
Depending on engine displacement, it is possible to install a hydrogen cell, in order to lower the amount or carbon dioxide in the exhaust gases.
The technical summary of the invention is characterized by a combustion process in which there is no lubrication oil, and the produced exhaust gases have lower standard levels of contamination. The ability of the classic two-stroke gasoline engine combustion to work with pure gasoline fuel mixture leads to a percentage increase in the power output of existing driver who has applied. The ability of the valve-less two- stroke internal combustion engine to operate by combustion of fuel without addition of lubricating oil to the air-fuel mixture causes the increase of power output and efficiency of the two-stroke engine to which this design is applied.
