Description
Technical field
The present invention relates to a kind of ordinary internal combustion engine thermal efficiency, the method that reduces the internal-combustion engine oil consumption and efficient low-consume internal-combustion engine of new structure of improving, belong to the thermal power machinery technical field.
Background technique
Traditional internal-combustion engine comprises that petrol engine, diesel engine, gas turbine all are to utilize the high temperature and high pressure gas that produces after fuel and the air burning to promote the mechanical device work done, produce machine power output.This process can produce a large amount of heats and waste with waste gas or cooling working medium.Thereby the thermal efficiency of internal-combustion engine maintains on the lower level, generally at 30%-40% all the time.Along with worldwide energy shortage, improving the ordinary internal combustion engine thermal efficiency, reducing the internal-combustion engine oil consumption has been the great technical task that the mankind face.Though the various countries backroom boys constantly proposes new technological scheme, does not all have bigger technological break-through for this reason.Explore and solve this technical task and can play immeasurable effect to the survival and development of human society undoubtedly.
Summary of the invention
The purpose of this invention is to provide a kind of ordinary internal combustion engine thermal efficiency, the method that reduces the internal-combustion engine oil consumption and efficient low-consume internal-combustion engine of new structure of improving.
Technical characteristics of the present invention is to utilize liquid working substance to absorb the residue heat energy of internal-combustion engine, make liquid working substance evaporation becoming gas, volumetric expansion produces high pressure, participate in directly and promote the mechanical device work done, under the situation that does not change internal-combustion engine basic structure, significantly improve the oil consumption of the ordinary internal combustion engine thermal efficiency, reduction internal-combustion engine.
In theory, the thermal efficiency of internal-combustion engine is associated with multiple factor, wherein the burning expansion multiple of working medium importantly.The burning expansion multiple of ordinary circumstance internal-combustion engine working medium is big more, and its useful horsepower is also high more.With the petrol engine is example, and its volumetric expansion multiple is 17834 times behind the 1 gram gasoline combustion, but the condition of its burning is to need comburant oxygen, and the oxygen content of air needs 11395mm when being generally 21%, 1 gram gasoline combustion
3Air.So calculate volumetric expansion behind the 1 gram gasoline combustion to have only 7.9 times of total material volume of the burning participated in, this has just limited the thermal efficiency of petrol engine.Although can adopt pure oxygen to replace air in theory,, often be restricted during actual the use to improve its expansion multiple.
The Hyundai Motor technology has extensively adopted the supercharging air technology, improves the air inflow of petrol engine, and the amount of oxygen that enters cylinder is risen, and has improved the thermal efficiency of petrol engine, has also reduced fuel consumption simultaneously.Its substantive issue is to have improved its volumetric expansion multiple behind the gasoline combustion.
The fact of the application of diesel oil emulsification on diesel engine is verified, sneaks into an amount of water in the burning chamber of diesel engine, can reduce the consumption of diesel oil, and its power does not reduce, and the emission status improvement, and this is a undisputable fact.According to the literature, the water mixing ratio of present German diesel oil emulsification still has use value near 50%.The problem that exists is a relatively difficulty of starting ignition, in case start successfully, work is no problem.
When jet fighter is opened accelerator, spray into excessive fuel in the firing chamber, acceleration that can the generation several gs of moment as rocket disengages aircraft fast.Its essence is the huge thrust of having utilized the fuel heat absorption to expand and produce.
The above fact can illustrate that it is not high that present traditional internal-combustion engine exists heat utilization ratio, wastes bigger problem; Sneak into liquid water in the fuel oil of internal-combustion engine, can alternative fuel supply with.So, as long as an amount of working medium is sprayed in the firing chamber of internal-combustion engine, absorb unnecessary heat, with liquid working substance heating becoming gas, gas just can be worked in coordination with the indoor gas acting of combustion in IC engine.Here it is key problem in technology point of the present invention can improve the power of internal-combustion engine on the one hand, reduces fuel consumption; Can improve the operating mode of internal-combustion engine on the other hand, become external refrigeration and be inner cooling, reduce the load of internal-combustion engine cooling system, simplify the structure of internal-combustion engine cooling system.
In sum, a kind of method that improves internal combustion engine thermal efficiency, reduces the internal-combustion engine oil consumption, it is characterized in that (in the firing chamber of internal-combustion engine nozzle being set) in internal-combustion engine ignition or afterwards in the firing chamber (continuously or be interrupted) spray into liquid working substance, utilizing liquid working substance to absorb in the firing chamber heat of vaporization expands and becomes gas, the work done of promotion internal-combustion engine.
