Description
Technical field
The present invention relates to explosive motor field, particularly relate to a kind of without carbon deposition engine.
Background technique
Along with the development of society, automobile production and sales volume constantly increase, and motor car engine carbon distribution problem constantly manifests, and carbon distribution is also the difficult problem in world car development history.The sediments that carbon distribution produces after referring to the gas blowby mixing partial combustion of internal combustion engine fuel and lubricant oil.It is reported, general about the 30000KM of system of Japan and Korea S vehicle should remove a carbon distribution, because system of Japan and Korea S open form majority is low turn high pili torti motivation, comparatively slow speed driving emphatically, carbon distribution affects relatively little on the power of engine and oil consumption.On the contrary, America and Europe is that general about the 20000KM of vehicle will remove a carbon distribution, America and Europe is vehicle majority is middle high rotating speed engine, reaching certain rotating speed becomes real power just to export, majority is middle high rotating speed driving, but in high rotating speed must first through the slow-speed of revolution, carbon distribution embodies more obvious on the impact of engine when the slow-speed of revolution is accelerated.During engine operation, because the friction between the burning of fuel and moving parts produces a large amount of heats, make the operating temperature of motor very high, the component (piston, piston ring, cylinder wall, intake valve, cylinder head, spark plug, head gasket etc.) particularly forming firing chamber directly contact with high-temperature gas, its temperature is higher, reach about 2000 DEG C, if suitably and timely do not cooled, motor is with regard to cisco unity malfunction.And adopting compacter design and there is larger specific power along with motor, the used heat density that motor produces also obviously increases thereupon.
Indicating oven temp. of engine can make lubricant oil become rare because oil temperature raises, the oil film of each lubricant housings of motor is not easily formed or is destroyed, semi-dry friction or even dry friction will be there is in each matching pair surface, easily cause that lubricant oil burns, carbon distribution and lose lubricating function, thus acceleration component wear, reduce the working life of motor; Engine overheat, metal parts is under long high temperature action, and its intensity, elasticity, wear resistance all can decline, and produce thermal stress, finally occurs distortion, crackle and expansion, and changes the matching gap between part, affect function of the engine; Engine overheat, the air heats entering cylinder is expanded, and air density reduces, and causes volumetric efficiency to decline; Diesel engine produces pre-ignition, and aeration quantity reduces, and frictional loss increases; Because air inlet amount reduces relatively, the mixed proportion imbalance of fuel oil and air, makes the combustion process of diesel engine abnormal, pre-ignition or deflagration phenomenon can occur, thus oil consumption increases, power drop, outlet pipe over-emitting black exhaust, and the reliability of work and durability worsen; Time serious, moving parts can be made to lose normal clearance because of expanded by heating, frictional force increases, and causes piston scraping or the pernicious fault such as stuck.
Summary of the invention
The technical problem to be solved in the present invention is to provide that a kind of structure is simple, good cooling results, good operation stability without carbon deposition engine.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of without carbon deposition engine, comprise cylinder block, this cylinder block is provided with water-cooled cavity and at least two sleeve ports, what each sleeve port all mated is provided with cylinder, on the cylinder sleeve hole wall contacted with cooling water or in corresponding cylinder piston stroke section cylinder sleeve hole wall on offer groove or the open-work of some.
The longitudinal section of described groove or open-work is variable cross section.
A kind of without carbon deposition engine, comprise single cylinder, on this cylinder outer wall contacted with cooling water or offer the groove of some on the cylinder outer wall of piston stroke section, and the longitudinal section of groove is variable cross section.
Described groove is round table-like, or is prism-frustum-shaped, or is coniform, or is pyramid-shaped.
The cross section of described groove is n angle star, and n is greater than 3 natural numbers being less than 10.
Spacing between described groove is 2 ~ 25mm.
The cylinder wall thickness of described bottom portion of groove position is 2 ~ 30mm.
The upper of described groove is diametrically 1.5 ~ 10mm.
Described cylinder outer wall and groove surfaces lining hard formation or carry out nitriding treatment, improve its surface hardness and degree of finish, as adopted chromium plating, nitriding, spray pottery, being coated with epoxy resin or being coated with the techniques such as nylon, coat different coating layers at cylinder outer surface and groove surfaces, effectively can resist the cavitation pitting of cylinder block outer wall.Also can be coated with anti-cavitation pitting material and absorbing material on cylinder or sleeve port outer wall, reduce its roughness as far as possible, increase the technical measures such as aiding support.
The present invention has actively useful technique effect:
1. increase the heat exchange area of cylinder outer wall and cooling water, be beneficial to and strengthen in cylinder and the distributing of cylinder wall heat, to reduce the high temperature of cylinder wall fast and effectively, keep the lubricity of cylinder, make cylinder inner wall moistening and as bright as a sixpence, and improve flexibility and the working life of the parts such as cylinder, piston, connecting rod, bent axle, prolonged engine life one times can be made; And high temperature sintering carbon distribution (motor does not almost need de-carbon all the life) can be prevented, make cylinder be in comparatively suitable heat load state, the Thorough combustion of advantageous fuel, keeps powerful power stage, saving fuel oil 5 ~ 13%.
2. adopt the present invention can not reduce the intensity of cylinder or cylinder block, simultaneously due to cylinder wall became uneven one, can reduce or avoid the generation of resonance phenomenon, to strengthen motor traveling comfort.
3. the present invention has that structure is simple, the heat load of good cooling results, reduction piston, cylinder, makes the more reliable advantage of its work, is widely used in various types of water-cooled IC engine.
